Nature notes

Early month: Grass growing well with the very mild start. Flowering Strawberries, Ladybird (dark with orange markings on the Camelia. Plenty of Redwings flying over now after dusk...lots of Fox & Cubs in flower verge past Grannell lane. Celandine foliage Neuadd lane. Cuckoo Pint has come back as it did last Autumn after dying off late Summer. New Rose front. Generally life inappropriately springing with fresh growth, baby weeds and plants, some buds opening, this all often happens during a very mild November spell such as this.

Fri 7th bat low flying over us back garden bigger than a pipistrelle.

Sat 8th Eco had a Red Admiral settle on her arm a she waited at the bus stop.

Sun 9th 'Spring in November' or a 'second a Spring': Grannell lane profuse fresh growth past week or so when rather it should be dying off from Summer (nights are averaging above 8c and higher than the October mean). A few grasses in flower again also some Nettles, generally a carpet of fresh undergrowth such as it would be in April inc much Cow Parsley foliage. Wild Rose shoots have sprung up with fresh leaves, various flowerings still lots of Fox & Cubs inc new ones, Hazel and some other hedgerows buds starting to open. Knapweed about to bloom on the bank opposite hotel.  Song Thrush in decent though not full song dusk.

Mon 10th S Thrush at end of garden in good voice today. Neuadd lane notables plenty of Red Campion and Cranesbill in flowers, Cleavers are up (don't recall seeing them in November before?)  2 S Thrush singing dusk (inc ours).

Sat 15th M Thrush singing.

Mid month fresh growth and flowerings, much evident in Long Lawford inc Daisies. On the journey back remarkably near Leamington of dozens of Dandelion clocks with others in flower!

Fri 21st severe frost zapped quite a bit in the garden here while in Aberystwyth not hard enough (-3c) and still flowers on the go. Did not seem as many Starlings at the pier dusk est 5 -10000.

Late month first tiny Bluebell spikes making an appearance under Apple tree. Don't recall this happening g in November before although they were well up late December 2015. Fresh Honeysuckle leaves Neuadd lane. Still plenty of fresh growth remaining intact month end. Sheep over the road still enjoying freshly grown grass.

Mon 13th bright and warm locally mid & N Wales, Gogerddan max 18.6c (warmest in Wales) cf a cloudy 15.9c here at Lwn. Mids generally below max 15c.

Fri 31st some torrential downpours about today with local thunder. Sferics over Carms late morning while an Hinckley PWS caught 13mm in an hour mid afternoon. Here at Lwn may just about have heard a couple of distant rumbles however there was too much wind and background noise to be certain, also the nearest sferics were some 12 miles south so borderline audible. Squally thundery showers more widely for Wales during the evening and overnight, here at Lwn caught out letting the dog out 2300 by the heaviest of the year to date (100mm/ hour). Then vivid lightning every minute or two for 15 minutes some 10 - 12 miles to the west with low rumbles of thunder just after midnight (and into November), more to the east towards 0100 and further torrential downpours.

Sat 20th spells of heavy rain much of WW giving over 3 inches for some, local thunder (inc here at Lwn mid afternoon). Many gauges caught around 2 inches today, and 4 inches locally, wettest NRW gauge Ysbyty Ifan near Blaenau Ffestiniog & Pwll Peiran near Devil's Bridge both 87mm; wettest MO station Swyddffynnon 67mm. Also of note 24 hours to midnight: Trawsgoed 67mm and Rhos Ymryson (5 miles from Llanwnnen) 62mm. Parts of the West Mids caught some of the heavy rain but no for long and  E Mids mostly stayed dry.

Sun 21st one of the wettest September days here yesterday 0900 total 37.9mm (wettest still 46.6mm  Sept 2018). 

A fine dry spell towards month end with plentiful sun but some cold, frosty nights:

Mon 22nd widespread ground frost and air frosts in places; here at Lwn min -2.4c was the coldest Sept night on record (beating -1.9c in 2018). Other minima Tirabad -1.7c, Pershore -0.4c, Swyddffynnon & Trawsgoed 0.0c, CITE +1.4c, Cov & Nott 5.6c, Aberdaron 7.8c. 

Then 4 more nights having at least a grass frost (all below 2c) here at Llanwnnen, such a run has not happened in September before. 

Nature notes

Fri 6th Aberaeron: still some active HM nests, many of this seasons nests have fallen down (hopefully post fledging). Several small groups of Swallow seemingly headed south along the coastline. 20+ HM evening. Sad case of the Razorbill, perhaps bird flu (young couple and Martin).

Sat 7th still some active HM nests near Morrisons Aberystwyth.

Still plenty of hirundines mid month; been quite a few butterflies this month especially whites and Red Admirals.

Sun 21st nice sunny day for a change, at least 2 Hornets and several Red Admirals enjoying the apple bonanza (most fruitful season ever here).

Mon 22nd around half dozen Red Admirals about the Apple trees, 2 Comma, Speckled Wood, 3 or 4 Hornets.

Tue 23rd no hirundines seen past couple of days and so they have gone now mostly.

Fri 24th Newquay a few Choughs by the shell fish factory. Also several distant Dolphins and apparently a Grey Seal.

Radar suggested 20mm locally SW Wales although  gauges caught much less (below 5mm).

Sun 31st showery, isolated thunder Mids, some very heavy and prolonged downpours parts of WW, here at Lwn downpours, some torrential during the evening and night (into Sept ) gave 25.8mm making it the wettest day of Summer 2025.

Nature notes

Sat 2nd no Swifts seen but chicks are still in the end nest west side.

Sun 3rd single Swift around the church for brief spells dusk.

Mon 4th Llanybydder evening: half dozen screaming Swift old warehouse, droppings beneath evidencing one nest

Aberduar chapel: 8 screaming Swift, much droppings and staining evident. 7 or 8 areas of wall staining from the soffit and around half dozen poo piles on the ground beneath.

Rhydybont chapel: no Swifts seen here but all the HM nests still intact with much activity from around 15 birds some chicks being fed in the air.

Dusk southern forestry possible snatch of distant Njar heard in fading light (2130) half hour after sunset coming from down by road it seemed as we headed back down to main track.

Wed 6th after sunset lucky to catch an adult Swift entering the nest that still has chicks (furthest west side) it screamed a bit too.

Sat 9th: single Swift among the Martins and Swallows feeding above the gardens afternoon, could not hear the chicks the other night. Then a pair  eve which were above Church  dusk. 

Farmer cutting hay for the second time this season (first was in June), most years they only manage one.

Sun 10th Lampeter on the way to Coventry single Swift early afternoon.

M50 lots of trees with yellow flowers similar to Laburnum although could not be as these flowered in Spring.

Tue 12th 12 o clock ride, Binley Woods: Chiffchaff singing first one heard since probably early July.

Wed 13th 12 o clock ride again: Yaffle laughing.

Driving back drought stress evident to some trees especially ROW area which saw the hottest weather yesterday. These trees at least partly browned off and Autumn looking.

Fri 15th Chiffchaff heard from garden.

2 Swift among hirundines over the gardens this evening, latest hereabouts was Aug 20th 2021 with 8 over Aberaeron.

Tue 19th 80 plus hirundines above the village this evening getting ready for the off perhaps?

Sun 24th still hirundines but much fewer than a week back.

Since mid month some of the Ash trees leaves shrivelled and died could be drought stress coupled with die back? Unfortunately the worst affected is one that was quite heavily lopped in July so hopefully it comes back next year.

Sun 24th plenty of hirundines back this evening.

Mon 25th (BH) Forestry evening: dried out little mud and only water trickle down by the main road track. Some trees suffering drought stress especially the recent planted in 2021 (Birch and Rowan mainly|). 

Generally some trees on the turn (in the Mids they were on the turn in late July).

Llanybydder car park: plenty of HM, also back above our garden this evening.

Apples looked ready from mid month and now dropping (this about a month early).

Thank you for reporting the issue with our Pencader rain gauge. There has been a fault identified in an underground cable at the site which is within Pencader Sewage Treatment Works which is not easily accessible so we will be reconfiguring the gauge set up with the help of one of our contractors. Presently there is temporary telemetry logger monitoring the site and this was not feeding the website. This has now been re-configured so should provide rainfall data from tomorrow.
