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).
