Nature notes

Sat 1st dead Mole wild garden towards the gate, they are starving or dying of thirst with impossible to burrow due to hard soils. Flies, small Hornet (?) and a wasp feeding off the carcass. This has disappeared (scavenged) 2 days later.

Early month: large flocks of hirundines as typical late Summer (all the youngsters) especially around the churchyard. Still hearing a Swift or 2 moving from within the hall eaves.

Mon 3rd driving past Aberduar half dozen Swift, none though at nearby Rhyd y Bont. These turned out to be the last ones seen in 2026.

S Forestry: Pretty much dried up though still greenery to be had, still trickles of water coming down the slope towards main track, able to access the track to the lane to Rhydcymerau as the very boggy area has virtually dried up. 10 Swallow.

Thu 6th 50/ 60 hirundine over the gardens this evening.

Early month hardly a slug, snail or worm to be seen past few weeks. Apple trees: first one plenty of green Apples some dropping, middle one hardly an apple (never has many), bottom one, few and small, shrivelling on the branch and a few dropping. Loads of White Butterflies.

Pond below the church completely dried out for the first time (although it came close in 2018), the horses were in it getting muddy but not wet. Grannell is but a trickle and could easily paddle across.

Wed 12th partial solar eclipse (about 94% here) 1830 to 8pm significant dimming and eery orange light for  half hour or so around 19-1930. Some barking dogs (not unusual), hirundines suddenly appeared overhead as they do closer to sunset but more confused, Doves fluttering around suddenly.

Thu 13th Longwood evening: the cleared area (after 2018 wind fall) regenerating nicely now, birches getting tall, plenty of variety with many Oaks and gorse, sallows, some Sycamore.

Fri 14th Aberaeron not as many HMs, plenty of nests 20+ although quite a few falling apart, only 2 seen with chicks still present. River very low a bit like 1995 as is the generally browned off landscape.

Sat 15th Lampeter Uni 3 Swallow chicks perched besides nest SU door canopy, opposite side of bridge doorway young in nest took fright of me and alighted, there must have been 3 or 4 and they were with the parents and another brood as more than 8 in total alarming over the stream.

Thu 20th driving to Midlands, lots of stresses trees and fair few succumbed. Most of the dead ones are smaller ones (under 10 years), a good percentage changed colour (gold, brown or yellow).

Sun 23rd LL: H Martin colony Lauderdale Close area just past Cherwell park, quite a few birds in the air and saw nests under the deep eaves of 2 houses (seemingly lots of similar sites available).

Wed 26th middle Apple tree again shedding (it did during the early July heatwave), so I gave it some water even though the forecast is for a good inch tomorrow!

Late month Beech mast from Copper by school very early.

Local history

Lady at S Forestry came by on horseback as we were exploring down the pronounced wide old track (presumed) in the NW corner just above the main road. She said it is a former drove road and that the NRW own the stretch I was on but past the next gate it was her property called Cader Inn (for the drovers). She told me a lot of interesting things about the local drove road network. She said back where my car was parked by the main gate was called Kings Cross it sounded like the drove continued ahead where the field is now to the cottage then the main rd (100 yards away). There was another drove called Williams road nearby, while the main road only came about it seemed about 1900 (this drove supposedly being the previous main road). Past her place she said was a ruin called Tal y Bont that may have been a toll house. The drove road came down from Llanybydder mountain and went to Llandovery (thence London?). The lane to Parc y Rhos was one as was the once to Esgairdawe somewhere along one of these was a place called Wem where the stone markers were still in place (she said there were markers too on her land).

Last week when the heatwave looked on for towards month end not just in England the 300 hr mark looked inevitable here at Lwn, however days of grey skies, spitting rain/ drizzle and just 20 - 22c maxima has made that much less likely unless the final 2 days are largely sunny (a possibility):

Nature notes

Not much bird song start of the month.

Thu 2nd Newquay, quite a few Chiffchaffs singing through the woodland path up from the car park to Maen y Groes chapel (never knew of this path). A few Swifts evening near the harbour then a pair at the gable apex corner of chimney (as first noticed about 5 years back). 

Sat 4th 10 to 12 screaming Swift a decent display.

Sun 5th S Forestry evening Chiffchaffs and ST singing, 20 plus Swallow back at main gate dusk.

Rhyd y Bont: 20 plus screaming Swift as drove past slowly.

Bidder dusk: 30 to 40 screaming Swift easily the most this season; much banging at warehouse and forming discreet parties of 20-25 repeatedly.

Mon 6th Aberaeron evening c 8 screaming Swift harbour.

Ciliau Aeron driving back dusk c 8 Swift village central by school.

Tue 7th 15/ 20 screaming Swift hall dusk

Wed 8th 40 to 50 screaming Swift over Lampeter this evening (perhaps a few hirundines inc).

Lots of Butterflies using the garden this month so far inc Whites, Red Admiral, Gatekeeper, Meadow Brown, Speckled wood, Blues, Tortoiseshells.

Thu 10th Rhyd y Bont chapel 15 to 20 screaming Swift, dozen or so HM very active about their dozen nests.

S Forestry upper gate Darragh zone rough but at least dried out tracks: Tree Pipits and Stonechats. Nightjar 2150 close as approached the main track traversing the rough felled area as close as 30 metres and went along the track calling a lot and swooping but just one wing clap heard, then after it disappeared distant churring but briefly.  This is potentially a good site as the trees (many saplings from the Darragh trees) grow.

Sat 11th church tower noticed for the first time this season as definite that Swallows were getting in and out despite the new louvres! They were seen and filmed to enter the south side and exit the west side. Perhaps the extra light afforded by the July heatwave and near unbroken sun permits them to see inside the belfry whereas earlier on it was too dark with the more cloudy skies? Most likely these are feeding a second brood by now (or first if they only just started going in and out again?) on several occasions I had earlier on thought they may have gone in or out as I have been paying special attention since the new louvres but could not be sure (back to May).

Mon 13th Swallow seen to enter tower just past sunset in fading light.

Blackbird has been feeding off the raspberries during this months heatwave, unfortunately the raspberries were doing well until the heatwave but are now shrinking and shrivelling up with few ripe ones left (normally going strong mid July still). Today a Thrush and a Blackbird feeding off small unripe blackberries clos to the extension, they must be getting desperate, there wont be many worms, slugs and snails now as the lawns are drying up. I have put plenty of containers of water out as well as the usual topping up the extension gutter that the Sparrows and sometimes Starlings use to bathe and drink (filling it up daily late afternoon as the shade comes over). Also have seen the Blue Tits in there quite often.

Mid month: chicks audible from only one place now in the hall (front near the bench) there should still be more at this stage as few would have fledged by mid July so suspecting high mortality due to the prolonged heatwave (maxima above 27c since early month) however would have expected to see dead ones that fell out were this the case so a bit of a mystery? 

Hay fever all but over thankfully as everywhere dried out excepting some of the outgrown refugia in the garden. Grasshoppers all over the lawns seem to love the heatwave, still lots of butterflies inc Gatekeepers, Speckled Wood, Painted Lady (?) or Large Tortoiseshell (?), Holly Blue, Red Admirals, Meadow Browns, Ringlet.

Thu 15th Aberduar good screaming party this evening, 12 - 15 birds with several entries to nest sites. Wall staining/ poo piles suggests 4 or 5 nests, could be more as newer soffit may be retaining some?

4 Swallow chicks perhaps a week or so old in porch would be the second brood as they had one in June.

S Forestry not much bird song now, the odd Chiffchaff and Tree Pipit.

Fri 17th driving to Aberystwyth many brown fields and hillsides getting a bit like 1995. Many trees showing 'Autumn' colours 2 or 3 months early and also shedding leaves, a few may have succumbed. 

Thu 23rd S Forestry: green still holding sway up here thankfully still water in places, the bit down by the main road has plenty of shade now as the trees grown around it but is turning boggy. 10 Swallow feeding, Stonechat family alarmed.

Rhyd y Bont driving past slowly 20 - 25 frenzied Swift dusk. Then car park about 20 of the same with entries seen to old station and warehouse, nests evidenced by poo on the ground below.

Fri 24th Newquay lots of HM counted almost two dozen nests, a dozen of which along Ivy Place (6 on one house alone see video). Solitary Swift early evening, droppings beneath the apex nest by car park.

Late month: Swifts much less evident now, no more chicks in hall I think, Fri 25th 3 arrived at dusk but none the following dusk.

Tue 28th handed out Swift awareness folders to meeting at church this evening. Awaiting approval for leasing the hall still, the church had its final service on Sunday and will soon be made redundant. I mentioned potential community & biodiversity grants from 'local places for nature'.

Lots of Swallows over the church dusk, no Swifts.

Wed 29th no Swifts Lampeter this evening, very quiet.

Thu 30th much Swallow activity church it was the fledglings from the tower. About 4 of them, the adults constantly going in and out of the tower but the chicks not yet getting the hang of it, fluttering around the louvre openings and congregating on the stonework framework of the openings. Watched and filmed them for near half hour, I am thinking they were not yet skilful enough in flight (this perhaps their first day outside) or that it was lack of light as to me it appears very dark going into the tower. Perhaps they are going to have to risk it roosting outside tonight (it was a cold night down below 4c)?

Also 2/3 Swift around, also could here some moving around within the nest sites (one west side and one from within the east side (N end). Pretty sure there are no chicks this past week or so.

Fri 31st Llangrannog: Plenty of HMs and their nests (as noted earlier in the Summer), 4 close to fledging chicks precariously sat in their nest above the former Tafell Pizza building, the nest has started to fall away with a large opening and looks far from safe. As no adults paid them a visit in the half hour we observed them most likely they are ready to go anyway! Filmed these.

Llanwnnen Swifts again audible from within the hall.

Swallows not attempting to enter the tower this evening (presuming the same ones), 10 of them had gathered on a wire over the junction opposite the Grannell by dusk (hopefully safe?).

Summary July 2026

Exceptionally warm, very dry and very sunny.

Some places had their warmest month on record such as here at Llanwnnen, mean temp 17.9c narrowly beating 17.7c from 2006. For others it was second warmest after  2006. At Coventry equal with 2026 (mean temp 20.5c (+3.1c). Mean temps generally 2 or 3c above averages.

From the Met Office:

Temperatures: Wales records its joint warmest July on record    

The dry conditions have been accompanied by exceptional warmth across much of the UK. Provisional statistics show: 

• Wales has recorded its joint warmest July for mean temperature on record, joining 2006 and 1983 with a mean temperature of 17.8°C  
• The UK has seen its second warmest July for mean temperature on record. 
• England has seen its second warmest July for mean temperature on record. 

Nationally both England & Wales had the driest July on record, the average for Wales being 9.3mm.

Driest month on record here at Llanwnnen) total 4.5mm  (beating 8.9mm May 2020). Only 2 drier months in the very long Coventry record (both previous months had 0.8mm)

Partial drought 42 days both June 17th - July 29th (9.5mm in that period) and again June 20th - July 31st (just 7.3mm averaging 0.17mm/ day). This may last a few more days into August before the expected showers next week?

No doubt a few spots had a 0mm month? Well not quite in our regions (driest Shobdon & Shawbury both 0.2mm), but Little Rissington (Cotswolds) 0mm. Also Tenbury Wells (Worc) a COL site 0.0mm.

Bablake 1.0mm = there have been just two drier months in Coventry (driest still July 1885 0.8mm and September 1959 0.8mm). As for Rugby area the driest month is??

Sunniest month in my estimations too here with 298 hours  beating 278 hrs from July 2013 (which was the first month of webcam estimations). Coventry 280 hours looks like only a couple of sunnier months in the city (record May 2020 288.5 hours). Much of southern England (and parts of Wales) over 300 hours.

Of note is that as of July 31st 2026 this year has had an estimated 1017 hours sunshine here at Lwn which is more than during the whole of 2024 (est 1011 hours).

Cooler and unsettled start to Summer 2026 after the extreme end of May heatwave:

Mon 1st useful rainfall at last, widely over an inch WW and locally Mids. NRW Rhydargaeau 44mm, Bontgoch 36mm, Abergorlech, 34mm, Rhos Ymryson 33mm. Llanwnnen 27mm the wettest day since January.

Tue 2nd showery, thunder widespread Mids pm, Cov saw a spectacular storm late afternoon as did many other parts of Mids. Radar suggested above 30mm close to SW Cov today (inc overnight frontal rain). Bablake caught just 2mm from the thundery showers this afternoon which tracked just to the south with Finham (EA) 7mm 17 - 1800.

Tue 9th showery, thunder in places, others missed it all: Here at Lwn dodged the showers after early morning, heavy showers passed close by to S late afternoon, drive to Lampeter 1620, got back and checked the radar there were sferics just 4 miles SSW at 1630 which must have been while I was driving as nothing heard. 2345 heard a long distant rumble, then a few minutes later one flash then heavy showers but no more TL. 2 nearby sferics showed, one near Newquay then one at Aberaeron so they were a good 10 miles distant but one audible.

Wed 10th another days of scattered showers, local thunder at Cov sferic and FB reports 1300.

Weather picked up a bit towards mid month:

Nature notes

Sat 6th Laburnum walk on a very cool (12c) wet misty evening. They are past peak but still showing quite well (they were early out this year). Did n't hear a Cuckoo but weather terrible. Wood Warbler, WWs, Reed Bunting, Stonechats heard.

Early month: after already reducing from mid May it seemed, bird song has lessened further into June (weather poor). Only seeing small numbers of Swifts still they must be feeding at distant due to the poor weather this month although they have chicks as attested by a few broken egg shells on the ground.

Mon 8th S forestry: still Laburnum bloom although seeding. Redstart, Tree Pipits, many WWs, Wood Warbler, Blackcap, Chiffchaffs, Swallows.

Thu 11th 5/6 Swift over the church although not vocal. No screaming parties so far this month (had them during the late May heatwave of course).

Towards mid month the cool unsettled weather of late has slowed things down somewhat with plenty of blooms ongoing and bird song perhaps picked up a bit cf start of the month.

Sat 13th 40 Jackdaws in commotion this evening as there was a BOP among them white rumped so a probable  Hen Harrier.

 9 or 10 screaming  Swifts  dusk church most this year so far.

Mon 15th S Forestry tea time  lots of birds and song, plenty  WW and Wood Warbler, CCs, Blackcap, Tree Pipits, Swallows, Wrens, STs, Mistle Thrush, heard Crossbills, Linnets I think, Chaffinches heard, Ravens, Pied Wagtails, Blackbirds, Pigeons, Bullfinches. 

Thu 18th hall has at least 3 Swift nests front side, one big poo pile, chicks audible from at least 2.

Sun 21st Neuadd circular evening: plentiful bird song still, BBs, STs, CCs, WW, Blackcap, Wren. Perhaps a dozen Swift and similar no of hirundines near Fish & Anchor then 8 to 10 Swift over the church (likely many same birds just flew half mile).

Mon 22nd Swift evening: large numbers (Bangers inc?).

Bidder: Car park 20+ screaming, Aberduar 20, Rhyd y Bont 15 - 20. 14 HM nests latter location counted looked intact a few still occupied (perhaps 10 seen around) and a few Swallows. Saw a couple by the hall/ gym, stopped and had a look around the back where full of holes in stonework cf recently renovated front building (demise of much of the HS colony).

Forestry: Grasshopper Warbler close by main gate 10pm arrival fading light. Gwylfa wastelands too barren awaiting a replant while the former Njar zone back along main track slopes, trees too grown now as 15 years old. No Njars heard.

Tue 23rd attended a meeting at the church regards future of the hall and playing field. The church is to close potentially could be a house in the future. As for the hall were enough concern raised and interest then a lease would be sought from the church for the next 25 years of the hall. They need to raise funds as it is unfit for people to use and obviously require much renovation/ modernisation. I brought up about the Swift inhabitants and that often they can be incorporated, etc, and that perhaps they would tick ecological boxes in a grant application but the response was that 'they could also untick boxes'. A committee the 'Grannell Group' was formed of about 10 members of which I am one due to Swift interests. Meanwhile the screaming Swifts above the attendees heads elicited little interest.

Wed 24th another very hot day, the Starling family have been around a lot during the heatwave (2 or 3 chicks left I think). One landed a few metres from me on a branch gaping, I thought due to thirst, however then the adult came and fed it with food from next doors feeders.

Uni 3 Swallow chicks lined up waited to be fed on the side wall of the Arts centre besides the stream. There are quite a few active nests too as with previous years.

Thu 25th S Forestry after the hottest day on record (max 35.2c Lwn) a very warm, sultry evening. Fairly quiet just a WW, CC, Blackcap singing and a Thrush. Njar called just after 2200 then some brief churring with distant thunder and lightning in the background. Made our way back down the rocky slope in fading light and to not get caught in a storm (which did n't arrive).

Fri 26th Llangrannog quite a few HM nests, several Chiffchaff singing.
