Many places were somewhat sunnier than average, a few parts of the Midlands slightly below. Here at Llanwnnen there were a fair few frosts albeit only slight (total 5 air frost, min -2.1c). Few places elsewhere saw more than a few ground frosts though throughout the month.

Nature notes

The mostly fine October saw some butterflies still about, especially Red Admiral during the first fortnight. Cold nights seem to have put paid to these after mid month.
First few Fieldfare and Redwing observed at Hawkesbury, Coventry 12th, these are Winter visiting Thrushes here to escape the cold of Russia and Scandinavia. Large mixed flock of these Thrushes seen near Llanwnnen 21st.
Two raven observed Alderman's Green, Coventry, don't recall seeing them in that area before.
Plenty of flowers in bloom throughout October along hedgerows and in gardens. Red Campion putting on a fine Autumn bloom, also few Foxglove, these very short compared with Summer growth having taken advantage of late Summer verge and hedge cutting. Various other not known wildflower in bloom also.
Holly berries turned red this month.

Nature notes

Spent 5 days in Coventry early in the month, not one House Martin or Swallow sighting, came back they were still quite plentiful mid month about Ceredigion, especially the latter. 

A few Chiffchaff heard back in song in the Coventry area as well as around Llanwnnen early in the month, they often give little (albeit more subdued) bursts even as late as the beginning of October ahead or during their passage back to Africa. 

A 'Yaffle' heard at Alderman's Green, Coventry early in the month, a bird rarely if ever seen in West Wales (answers on a postcard please!). One then spotted near Coombe Park, Warks late month.

A few House Martin over Coventry toward month end, also a few Swallow sighted to late month they may well be migrating at this stage. No further Hirundines spotted back home after the 26th.

Temps around average and so felt reasonably warm in any sun (Pershore 23.4c, Llanwnnen 21.3c, Aberporth 20.3c)

Fri 29th rather cloudy and quite cool most of WW with a few light showers, Cardigan Bay especially cool while proved the exception Anglesey with decent sunny spells. Sunny intervals and aome showers Midlands where temperatures were average to warm (Pershore College 24.4c, Church Lawford 23.5c, Milford Haven 18.7c, Aberdaron 16.2c. Swyddfynnon 15.9c max, Valley 9 hrs sun)

Sat 30th a cool night for Mid Wales and the Marches (Shobdon & Tirabad 6.6c, Llanwnnen 7.5c). Early local fog patches (inc Llanwnnen) cleared to sunny spells, just the odd isolated shower, most places having a dry day. Temperatures ranging from rather cool to average (Pershore 21.6c, Milford Haven 20.4c, Aberporth 17.0c)

Sun 31st cool night (Llanwnnen 5.7c, Pembrey 6.2c, Shobdon 6.7c). Cloud and sunny intervals most places dry. Temps around average so feeling warm in the sunshine (Hereford 22.4c, Pembrey 19.8c, Llanwnnen 19.6c, Aberporth 16.6c)



July summary

Headline: generally rather dry with temperatures around average; dull WW, near average sun Midlands

The first half of July was decidedly dull and cool, in fact the month ended up a very dull one for WW but closer to average for the Midlands. Only 2 days were truly sunny here at Llanwnnen all month (with at least 10 hours of a possible 15) and the total sunshine amounted just over half the July average.
Warmed up considerably second half with a brief hot spell, although the Midlands remained very warm for the best part of a week. Many places had the hottest day for a decade on the 19th as temperatures topped 32c in places.
Most places below average rain-wise, although NW Wales wet, locally very wet, parts of the Midlands on the other hand had a very dry month. A peculiarity of the month here at Llanwnnen was that although the total was only % of average it fell on 21 days usually in small amounts and so the grass was often too wet to cut even though much of a day may have been dry, the lack of sunshine not permitting the usual Summer evapotranspiration rate.

Nature notes

Mid month: bird song as is typical as we progress through Summer had died down considerably early in July, just a smattering of Chiffchaff, Blackcap, Song Thrush and Blackbird remain to utter somewhat half-heartidly and briefly. Much concern over the Swift breeding success this dismal Summer, there were 4 or 5 nests with chicks audible at the Llanwnnen colony late June, struggling to hear any now, presuming most if not all may have met their fate with adults unable to procure sufficient insects given the predominance of cool, dull, breezy and damp conditions. There were plentiful screaming adults most of June, however they have been only infrequently observed during the past fortnight or so and in smaller numbers suggesting they have had a failed breeding season. This I find upsetting and unfortunate as this my favourite bird is on the decline as it battles our all too often poor Summers along with insufficient suitable nesting sites as our revamped and modern buildings are tightly sealed against them, along with whatever misfortunes they encounter during migration or wintering in Africa. Good news is that more and more people now provide Swift boxes (often with cameras to enjoy the antics) which Swifts eventually will take too given audio encouragement and can enjoy learning more about these marvellous mysterious 'Devil birds' !

Swift postscript: Good news: The hot spell just after mid month saw fantastic frenzied Swift activity, and I could hear chicks on 4 of the nests so nowhere near a disaster! Up to 14 screaming Swifts observed on the very hot evening of the 19th.

Mon 19th returned to the slopes of Mynydd Pencarreg in the hope of hearing Nightjars as in June but no luck, however there was a wonderful Grasshopper Warbler serenading the Full Moon as it was getting dark after 2130 and only 50 metres off the lane.

Tue 20th: Thought the heat had zapped the Hydrangea as when I arrived home in the evening all the blue flowers had wilted, however I gave it a good drink and in the morning it was right as rain!

Weather log June 2016

Weather log June 2016

Sharply contrasting fortunes west to east early in June:

Wed 1st warm and fairly sunny WW, in sharp contrast much of the Midlands very cool and cloudy with a little rain in places (Trawsgoed 22.3c, Coventry 12.4c, Nottingham 12.1c)

Sun 5th sunny spells eventually everywhere, warm or very warm, the odd isolated showers over WW later (Porthmadog 27.8c, Newport, Salop 23.7c)

Mon 6th very warm with sunny spells, the Midlands mostly sunny.  WW cloudier pm with many places catching showers or thunderstorms later, and there were also isolated late evening showers and thunderstorms over Worcestershire and Shropshire (Porthmadog 27.6c, Llanwnnen 26.5c, Newport, Salop 25.8c)

Wed 8th very mild night Midlands (Nottingham min 14.9c). Most of WW dry, bright and warm, warm too Midlands but showers and thunderstorms in places once more, notably the Birmingham and the Black Country around teatime with disruption and damage caused by torrential rain and flooding with perhaps over 2 inches falling locally in less than two hours (Pershore 26.3c warmest in UK, Llanwnnen 23.4c, Winterbourne 32.6mm wettest in UK)

Thu 9th warm with spells of hazy sunshine, some heavy showers over Mid and North Wales and Shropshire (Llanwnnen 25.2c, Newport, Salop 24.5c, Trawsgoed 24.3c)

Fri 10th one of the warmest nights so far this year (min Mumbles 15.6c, Shawbury 15.2c, I classify above 15c as a warm Summer night!). Rather warm, mostly cloudy some rain later WW, sunny spells Midland. Thunderstorms broke out across the North Midlands in particular afternoon with localised flooding, almost an inch in less than 2 hours at Market Bosworth early evening (Pershore 24.1c, Llanwnnen 21.8c, Trawsgoed 21.2c, Market Bosworth, Leic 24.6mm)

Sun 12th some rain or showers, with thunder for parts of Midlands late afternoon into evening, inc Coventry and Rugby areas, near normal temperatures (Hereford 22.2c, Llanwnnen 20.2c, Milford Haven 19.3c, Pershore 20mm daytime rainfall)

It has been the warmest start to June for a number of years, here at Llanwnnen no June has been warmer than this one in the 11 year year record but it may well cool down somewhat come month end. Mean temperature to June 12th 16.3c, previous warmest whole June 2007 (15.4c). However a cooler unsettled convective interlude then occurred mid- month:

Mon 13th cooler and mostly cloudy with some rain or showers, once more with localised very heavy downpours (Pershore 19.3c, Aberdaron 14.2c, Gogerddan 22.0mm)

Tue 14th generally rather cloudy and showery, some longer spells of rain, some prolonged torrential downpours and thunderstorms for parts of North Wales and the Midlands, the Birmingham area hit by flooding for the second time in a week a very few places escaped with a mostly dry day though. There were alos funnel clouds over various places including Rugby. Temperatures varied from decidedly cool around Cardigan bay to a rather warm feeling average for parts of the Midlands (Coton-in-the-Elms 20.4c, Aberporth max 13.4c, Market Bosworth 43mm, Porthmadog 33mm, Coleshill 32.6mm)

Wed 15th further showers or longer spells of rain, torrential with thunder in places once more. Parts of Birmingham may well have had 100mm/4 inches in the 24 hours to this morning as suggested by rainfall radar, with a PWS at Hodge Hill measuring just over 100mm, some places escaped generally dry and even bright however. More funnel clouds recorded todayTemperatures rather cool where cloudy and showery, around average if bright (Church Lawford 19.3c, Llanwnnen 18.9c, Porthmadog 40.6mm, Winterbourne 39.2mm, Pembrey 32mm by day, Valley 14.2 hrs sun)

Flooding in places again with some very large rainfall amounts locally, parts of Birmingham and the Black Country badly hit yet again. A PWS at Harbourne, Bham recorded 76mm today, bringing the June total thus far there to a staggering 155mm already compared with a modest 33mm at Long Lawford and a mere 12.4mm at RAF Mona! It felt pleasantly warm in any sunny breaks although most places were below the June average (Porthmadog 20.1c, Pershore 19.5c, Aberporth 15.0c, Winterbourne, Bham 50.4mm)

Rainfall distribution 24 hours to 1200 Fri 17th June 2016

Fri 17th generally a much drier day although still some few thundery showers about, especially the SW Midlands and around Swansea. Rather cool with a north breeze although some places still well up to average (Pershore 21.2c, Aberporth 14.3c, Mumbles Head 28mm)

Mon 20th quite a warm night (Shawbury 15.8c, Trawsgoed 15.3c) with spells of rain affecting most ny dawn. Rain soon cleared WW but not the East Midlands until midday, sunny intervals and a few showers following. Maxima around average, although the SW Midlands was rather warm (Pershore College 22.6c, Pembrey 19.1c)

Tue 21st dry with sunny intervals eventually, Anglesey sunniest place in the UK, temps near or a little below normal (Hereford & Pershore 20.6c, Llanwnnen 18.7c, Valley 10.2 hrs)

Thu 23rd Midlands in mild air overnight, cooler air across Wales (Coleshill min 15.4c, Llanwnnen 7.1c). Contrasting fortunes, with WW dry with sunny spells while the Midlands was mostly cloudy with a little rain for parts of the East Mids. Anglesey blessed with another sunny day (Valley 14 hrs), Temps near or a little above average (Shobdon 22.5c, Llanwnnen 19.8c, Mumbles 19.5c, Aberdaron 16.0c)

Fri 24th sunny intervals and scattered showers, heavy in places, but many places stayed dry, near normal temps (Church Lawford 21.3c, Llanwnnen 19.2c)

A very poor end to the month ensued in contrast to the fine warm weather early in June:

Sat 25th showery and rather cool, WW drier pm, thunder for parts of Midlands inc Coventrty and Rugby, a funnel cloud being photographed over Coventry afternoon (Pershore 20.0c, Pembrey 18.9c, Aberporth max 15.5c, Swyddfynnon 18.8mm)

Sun 26th cool cloudy and rather wet Wales, light rain and drizzle spreading to most of the Midlands by evening, temps nearer average for much of the Midlands (Pershore 19.8c, Valley 14.3c)

Wed 29th further spells of rain, especially WW during the morning, some very heavy downpours here, the rain lighter and more intermittent over most of the more southern Midlands Rain cleared later to just a few showers, but over an inch of rain fell onto some of the Welsh hills. Another  cool/ very cool and breezy day (Newport, Salop 18.5c, Little Rissington max 14.4c, Tirabad, near Llandovery 31mm)

Thu 30th  occasional rain, chiefly for Wales, very little for much of the Midlands. Cool/ very cool WW, nearer normal temps Midlands  ( Wellesbourne 19.8c, Capel Curig 13.6c)


June 2016 review: fine start but deteriorated; fairly warm overall but generally dull and wet.

Rather a warm June, around 1c above average, this due though to the mildness of predominantly cloudy nights, with daytime warmth at a premium after the first 10 days and there was a distinct lack of that mythical 'Glorious June' heat! For example Llannwnen only one day got above 20c after June 12th!
All areas had a wet month, some only marginally above average, while some had well over twice the June average.
Sunshine: dull especially so the Midlands, only a few coastal spots of WW attaining average levels. The duller parts of the Midlands barely had 100 hours, little over half the average sunshine, compared with just over 200 hours at Valley, Anglesey.

Some June rainfall totals:

Capel Curig 176.6mm 132%
Trwasgoed c. 170mm
Llanwnnen 86.6mm 127%
Aberporth 75.6mm 129%
Pembrey 115.2mm 152%
Llanelle PWS 102.6mm
Mumbles 130.8mm 205%

Nottingham 139.0mm 220%

Nature notes

Thu 2nd first Foxgloves in flower at Laugharne then Fri 3rd noticed  a few in flower while cycling in the Lampeter area. First Whitethroat heard about this time then by the 10th they could be heard singing widely so perhaps were late arriving this Spring.

Mid month luxuriant lush growth after the warm dry start to June and subsequent rains. Foxglove out profusely, few Butterflies as yet this Summer though. Still the odd Bluebell in flower in the countryside higher up. Nice show of Laburnam next to produce its supposedly deadly poisonous seeds!

Fri 17th Grasshopper Warblers heard Mynydd Pencarreg slopes, also Nightjars seen in display flight and heard churring after dusk same area

Late June: Song Thrushes singing as late as 2220 when its getting quite dark. Swifts seen flying and feeding until this time too, and in addition this is when the Owls start hooting and calling. Poor weather last few days of June hardly any Swifts seen, hopefully the young in the nests are getting enough food and warmth. Some Foxglove have completely seeded with no flowers left on stem, most though still have flowers appearing towards stem tops still.

Weather log May 2016

May 2016 weather log

May started quite chilly with widespread ground frost some nights and localised slight air frosts (Shobdon -0.7c 4th for instance). It warmed appreciably by the end of the first week to give us an early taste of Summer!

Thu 5th ground frost again in many places but a warm sunny day as some places topped 20c for the first time this year (Llanwnnen & Pershore 20.6c)

Fri 6th in spite of the surrounding warmth Friday again dawned with grass frost locally (Llanwnnen air min +1.3c, Pershore & Shawbury -1c on the grass). A warmer day for many although with the sun weak and hazy (Pershore 21.3c, Llanwnnen 21.2c)

This was the highest temperature I have recorded here so early in the year since April 2007 when it reached c. 26c, it was also the highest reading during the first half of May, although May 2012 saw an exceptional 28.1c towards month end.

Mon 9th warm night (Mildford 16.1c min, Shawbury 13.9c). Another warm or very warm day with some hazy sunshine, although WW rather cloudy with showery rain and in places thunderstorms later on.

Fri 27th scattered thunderstorms across Wales, severe in places, with hail and localised flooding, over 3 inches falling in parts of the western Brecon Beacons . Midlands dry, fine and quite warm as was most of NW Wales (Astwood Bank 19.7c)

Sat 28th rather warm with sunny spells, thunderstorms again broke out across Wales, a few quite severe with localised flooding (inc Lampeter and Pencader). Swyddfynnon near Tregaron, Ceredigion was wettest place in the UK with 31.2mm of which 25.2mm fell in the hour 17-1800 during a thunderstorm (Llanwnnen 21.4c, Pershore 20.0c)

West was best to end the month, warm and sunny for Wales, the Midlands seeing rain and strong winds by 31st..

Sun 31st Porthmadog 22.2c warmest place in UK compared with max 17.1c at Coventry, most places were sunny though
