A 100% blue sky day yesterday, and despite a gentle onshore breeze and the coast being a few miles away it reached 24.0C, the warmest of the year so far.
A summer temperature range adjusted for here where what I consider proper heatwaves are harder to achieve, would be something like:<15C Very Cool
15-17C Cool
18-20C Indifferent (can be comfortable, or feel cool if breezy etc).
21-24C Warm (pleasantly)
25-27C Very Warm
28-31C Hot
32C+ Very Hot (rare, seen at Exeter airport in 76, 83, and 90).Summer average is around 21C.
Of course it's subjective, I've felt pretty 'hot' in the sun in the low 20s, or been in the shade with a breeze in the high 20's thinking it doesn't feel that hot. I've been somewhere 33C was described as 'not a hot day' (it was cooler than the 39C the day before).As for the general public, I believe a lot say they like hot weather but what they are thinking about is an air temperature in the 20s and sunbathing on the beach etc. When the air actually 30C+ many find it uncomfortable in my experience, and even mistake the feel of genuinely 30C+ air as 'humidity', even though the dew point is 12C (this was the case at a BBQ in Reading in 2018). A lot of people seem to moan about the 'humidity in Britain' even though we aren't that humid compared to many hot climates.

Not too bad here on Thursday and Friday as we were just about in the shadow of Dartmoor. Sunny intervals, feeling warm/muggy in the sun but cooler at times when there was more cloud. About 21C. Could probably describe it as 'nether here nor there' weather. A few miles to my west towards Exeter, it was more like 23C which contrasted with Plymouth being 15/16C.
I can see why some on the south coast were disappointed recently though, some nice days/afternoon here had cloud to my east.
Yesterday turned into a stunning day with a max of 23.2C. if I ignore my interest in meteorology or the novelty of feeling higher temperatures, I don't really need it any warmer tbh.
Another stunning morning today, already 21.2C although a light onshore breeze will put a cap on that.-

Blimmin Eck, the G7 leaders must be kicking out a lot of hot air down there!

People often focus on the negatives. Sometimes you get cloud under high pressure but sometimes you get sunshine under low pressure.
At least it's clear for the weekend, If it was the other way round, people would be moaning how nice it was during the working week only to be cloudy at the weekend.. but when it's the other way round, that's not mentioned and people just moan that it's been cloudy at all.
If there was a nice chart showing for 16 days away I doubt it would have been posted either.-

The cloud and eclipse is actually working quite well here, in that it thins enough at times to see a silhouette of the sun with a chunk missing without any equipment (although you're probably still not technically meant to look at it).

I'd say it's been about average far this month here, maybe a touch above. Almost fully sunny yesterday. Also had a couple of sunnier days when further east was cloudy.
Some cloud and sunny intervals this morning. Tomorrow and Friday looks cloudier but Dartmoor can sometimes break up the cloud a bit here in SW tropical maritime airflows.
I notice temps are only forecast to get up to the low 20's here now though. Met Office has 21C every day from tomorrow to Monday. -
Interesting temp profile this evening, west is definitely best

Yesterday we saw a min of 1.4C, then it reached 12.4C at 10:13 this before settling around 10-11C in the rain and wind.
It would probably have been about the same temperature with that set up in December (although I guess that's not too surprising when you consider the sea temperatures are currently similar to December, they are usually their coldest in late Feb/early March).
Max today was 12.8C even with some decent sunny spells, and a heavy shower with hail dropped the temp to 7.2C at 12:15pm.
My May rainfall total now stands at 186mm! -
The line feature last night managed to split with us passing through a 2 mile wide gap. A fair bit more rain a few miles north of here. Even so, I got 14.6mm of rain.
1.2mm so far today.
That brings May's total up to 183.6mm. Quite possibly a record, but not sure (there doesn't seem to be any official stations around here with continuous long term rainfall records that are publicly available..)
This is all according to the Davis VP2, though it's been very close to the manual gauge since getting the new tipping spoon mechanism.

You guys ought to quit golf and take up windsurfing, then you'd get a different appreciation for this weather!

Will be in Bude tonight, looks like it's going to be very noisy. Quite an active October, this.
Just said the same to a friend lol apart from every October I've recorded has been warmer by mean temp, mean max, and absolute max!

It looked like most showers had missed here today but then a torrential shower with a couple rumbles brought the total to 9.2mm in 10 minutes.
We've now had 153mm this month, with 146.6mm from the 8th onwards.
Wettest days:
8th: 20.8mm
12th: 25.4mm
13th: 34.8mm
15th: 14.6mm
16th: 31.0mm
The 12th & 13th was persistent rain which brought about 57mm in 24 hours (barely stopped raining), with 60mm in total. That didn't cause too many problems, but quite high river levels and some rivers had their usual flooding on low lying floodplain areas.
However it left the ground saturated so yesterday's heavy downpours which saw 31.0mm here (40mm+ recordings a couple miles away), did cause flooding issues from surface water and smaller streams around here, with a few roads blocked. The 'flashy' River Sid also had a brief peak to its highest level since November 2016.
A torrential downpour at the end of the rain yesterday gave me 5.0mm in 4 minutes and 7mm in 10 minutes. Today I also had 4.4mm in 4 minutes and 7.6mm in 10 minutes.
May had been the only month in my 2008-2020 records not to see over 100mm, but this year it must already be one of the wettest on record, but I'm not sure what the local record is. I guess if the weather's going to be a bit rubbish it may as well do it in an interesting fashion.-

Rain seems to have stopped here for now, about 24 hours since it started.
Rainfall totals from the Davis VP2 are 57.2mm of rain in the last 24 hours. 25.4mm before midnight, and 31.8mm afterwards.
94.8mm this month.
Just need it to warm up and things will grow rapidly. Oh. -

Well, the UKV was crap at predicting this rain, even at 6 hours out.
Latest:
For the last 2 - 3 days it was showing that much further East, and consistently. Fail.
I noticed ECM didn't do well even yesterday morning either, interestingly the GFS seemed to do better, been indicating slow moving heavy rain over me for a couple of days.
50.8mm of rain here since mid afternoon yesterday according to the Davis, and rising. 25.4mm before midnight, 25.4mm afterwards!
Pretty much 21 hours of continuous rain. Eased off to light/very light rain at times this morning but it's moderate again now as another band has swung in from the NE. -

1983 failed to reach 20c until sometime in late May.
Yes looks like it failed to breach 18C at Exeter Airport that Spring. I wouldn't mind a repeat July 1983 though, slightly hotter than 2006 down here with 4 days of thunder at the airport.

13C with some sunny spells this morning, so not feeling too bad although the max temp was a few degrees below average again, then clouding over with rain starting mid afternoon. Now it's just 8.4C with persistent rain.
Looking at some model runs, I'm wondering if we could go through the whole of April and May without anything above 16C here. What's a bit more likely is that my highest maxima of the spring will be 18.6C on the 30th March, although the end of May is a long way off.
No other spring in my records (2008-2020) didn't reach 20C, although 2013 took until the 31st May (21.8C), and had only reached 17.4C up to the 30th May. -

Whole heat tornado incident from two days ago.
I noticed at about 11:40 it carries lava off past the flow margin which contributes to more smoke later on, presumably moss/grass fires.
Flank collapse at 8:46 local time this morning, and 8:59 had a particularly high fountain... spot the people to give a sense of scale!
It only did one more fountain after this one, before someone pressed the 'slow but continuous' button. Even after it died for about 10 minutes like usual it didn't fountain again interestingly enough, just started the continuous flow.
I wonder how far smaller pieces of tephra that aren't picked up on camera get lifted in the rapidly rising hot air.. which presumably cause the grass/moss fires if hot enough. I noticed small pieces falling at the camera location a few minutes after that fountain.
You can still rewind to the time of the above fountain for about 2 hours after my post -

Even here I don't think I could claim that the daytime weather was awful. There was a nagging cold wind though most days which made anything but cycling or running unpleasant without a couple of layers on.
And while April evenings aren't known for their warmth, the longer day-length particularly at the back of the month means that the outside is often tolerable until 9ish, while the mornings can still be quite chilly.
And of course if any year could have done with a warm anomaly in the evenings it's this one.
All just opinions of course, and different people find different weather pleasant. I think if we weren't hoping to spend more time socialising outside, I'd have considered this April decent and forgotten about it in a couple of years. Context is everything though, so I can't help but feel a little let down.
Yes, I'd expect London to get the most 'pleasant evening' temperatures, and the dominant airflows would have detracted from that more in your area than here this month, where we often get sea breezes/general onshore wind in warm spells anyway.
Here we had quite a few 15C days even if it was frosty by dawn. -
I'm a bit late posting this but I went to Bristol on Sunday for a meet up. It was nice enough, had a light jumper but had to take it off sat in the sun and when walking. It was busy outside with many places full for outside lunch.
Trees were greening up:
It felt like many days in April (at least the 2nd half) here, and made me think was April really that bad in terms of daytime weather?
Cool yes but dry and sunny. It was good for being active outdoors here, not for sitting out in a t-shirt in the evening but I don't expect that in April apart from maybe on a few days some years. Though I get it might be annoying to be kept waiting for Spring warmth and admittedly the west has done better, I may have a worse opinion if I lived in East Anglia or Kent.
For some perspective of how April has warmed, here's the average maxima compared to the 1961-90 average!
The average minima was remarkable of course, and the present weather is poor for May. If this keeps up for too long I might join in the moaning. -

Could be worse, like getting murdered is worse than being repeatedly punched in the face, having your car stolen and your house burned down, but that doesn't make the latter any better.
Alright.... I thought I was just posting something that some might have found interesting.
Anyway, I was hoping we would get some more average temps with W/SW winds next week even with some rain as some models hinted at that. However, it's trended towards a continuation of the cold airmass, so cool days (and cold nights), and potentially cold wet days when lows run into the UK, at least at first.
That would give me more moan about. In reality, although we've had a remarkable number of frosts this April, it's not been too bad by day here, if a bit cool. A sunny month too. My mean maxima is 13.0C, ahead of 2008, 2012, 2013, and 2016.
I'm definitely ready for a warm up though. -

End of April, middlE of the afternoon and the temps fallen to just 6c under the rain. That’s just not good enough, simply awful
Could be worse, though arguably more interesting:
Philip Eden: The 1908 snowstorm | weatheronline.co.uk
WWW.WEATHERONLINE.CO.UKOne of the most outrageous weather events April has ever given us occurred in 1908. Four days of heavy snow hit many parts of southern Britain from theQuoteFour days of heavy snow hit many parts of southern Britain from the 23rd-26th, while Scotland and northern England endured unprecedentedly severe night frosts.
QuoteA phenomenal blizzard raged all day on the 25th across Wessex, the Thames Valley, and much of the Midlands. In a ferocious snow squall that afternoon the cruiser 'Gladiator' sank in Southampton Water after it was holed following a collision with another vessel. Worst hit by the snowstorm were north Hampshire, Berkshire and Oxfordshire, and in the district bounded by Andover, Whitchurch and Kingsclere snow lay over 60cm deep at the end of the storm. Even in the city of Oxford the official observer noted a maximum depth of 42cm, the heaviest snowfall in any month there since February 1888, and not equalled since, while in Southampton the fall amounted to 37cm.

Another day of full sunshine, so that's 9 out of the last 10 days.
A max temp of 14.8C, about average for the end of April, so a good day overall. It's fantastic weather for being active! The breeze did have a slightly colder feel this morning though.
Some talk about Spring foliage being the latest people have seen, but surely 2013 was later? Gradually getting a bit greener here, more trees (e.g. Oak, Beech) coming into leaf. Apple blossom is starting to come out. Obviously later many recent springs, but not sure how far behind the long term average we are here (peak apple blossom is traditionally early May).
Obviously may be different in other places as I haven't been there.
If we get cool damp weather through May I'll be getting more fed up though.-

These guys didn't mind the arctic conditions yesterday!
Here a few miles inland, another pleasant sunny day today, max 15.4C so at least average for the end of April again. -
Well, 7 of the last 8 days have had virtually full sun here, and the next few look similar.
188 hours of sun so far, so it looks like beating April 2020 here (208.5 hours, both totals slightly under the true value due to early morning shading).
Also only 2.6mm of rain so far.
Those two aspects are reminding me a bit of last May (though then I recorded a very impressive 303.8 hours of sun).
Temperatures obviously a lot lower, 16 air frosts here. Feels a bit of an unusual month really, however it's been great for working outside recently, have hardly got wet this spring.
Also last Saturday at only 12C was still quite nice to sit out when my cousin visited, just a light jumper needed. Ok the air may feel cool in the shade and it's not shorts and t-shirt weather but I don't expect that for most days in April.-

Summer 2021: Moans, Groans, Ramps and Banter
in Spring Weather Discussion
Posted
Indeed! I've noticed it a fair bit in online comments too. Another one is associating hot houses at night with humidity even though it isn't humidity that's causing the houses to be hot.
I wondered if it was a more common miss-association down here because people living in Devon and Cornwall (especially near the south coast) rarely experience 30C+ air. However at this BBQ was in Reading everyone seemed to be doing it, including some that had lived in South Africa saying 'this is like Durban humidity' lol
