In Absence of True Seasons We need the sunniest and driest summer on record to even have a hope of an average year. 2024 will be the wettest year on record, it's never ending.

danm It doesn't help when it's also overcast, which means the ground will stay damp. Not what you expect to see at the end of spring.

Wade 12 months in a row with 50mm+ is ridiculous. The previous record is 9 months, and we only average 5 months of the year with 50mm+ on average. 2024 will almost certainly be wetter than 2014 now, as we have 8 months still to go, 3 of which are the wettest months of the year (Oct, Nov, Dec). 2025 better be dry.

After 1 day of May, Heathrow has less than an hour of sun and a quarter of the monthly rainfall already. 12th consecutive 50mm month incoming?

danmThe KZ sensor at Reading seems to regularly record more sunshine than the CS does though. Warsaw at 1900 hours of sun vs 1570 on the old CS seems completely inaccurate.

danm I think Reading University used both instruments in the same place, and the KZ there always records higher values than the CS instrument. It seems to be completely random whether the KZ or CS records more at a particular location, but some places have started recording wild values since switching to KZ (eg Warsaw, which has gone from 1570 hours during 81-10 to 1900 hours for 91-20).

137.7 hours for London in the end. Pretty terrible for April!

Wade And now we have been in an extended wet period since September 2022, with 11 consecutive months recording more than 50mm rainfall. Lets look at my annual rainfall for the past 10 years. The only year that stand out are 2014 (the wettest year on record) and 2023 (a top 5 wettest year). 2014: 864.0mm 2015: 562.0mm 2016: 590.6mm 2017: 572.2mm 2018: 580.0mm 2019: 652.2mm 2020: 662.6mm 2021: 653.4mm 2022: 576.8mm 2023: 769.2mm 2024: 304.6mm after 4 months!!!

Wade24-29.9c would be decent for my area if it was consistently sunny and dry and wasn't chilly at night. Cold nights are the death of anything summery. The law of averages would also suggest the current run of extremely wet and dull months that we are currently in is also not feasible, yet here we are.

Wade The only way that would be acceptable is if we had temps of 24-29.9c throughout the summer, and nothing outside of that range. I think we will have to wait until early June to get a 25c day.

Absolutely no chance with the unprecedented amount of rainfall we have had over the last year. We will need pretty much zero rainfall for May and June to get the ideal soil moisture for July and August to attempt anything record breaking, and that just isn't going to happen. I can't see us getting anything above 35c this year.

London, April 2024 - slightly warmer than average due to mild nights, very wet and very cloudy. Avg max: 15.0c (0.0c) Avg min: 7.2c (+1.2c) Mean: 11.1c (+0.6c) Rainfall: 68.6mm (162%) Sunshine: 137.7 hours (78%)

Summer8906 According to Environment Canada, Edmonton airport averages 89.8 days per year above 20c, 2.6 days above 30c. London averages about 105 days above 20c, 4.7 days above 30c. London also gets 35c days more often. It just appears that London is warmer throughout the summer.

stainesbloke That sounds more like August 2007, which was cool and breezy. August 2009 was slightly warmer, drier and duller than average. Av max: 23.9c Rainfall: 39.6mm Sun: 188 hours

With the last 2 days of April both recording 10 hours of sun, we will close April with 139 hours (78% of average). It also means that the 1959 sunshine comparison is still alive. Jan: 76 vs 77 Feb: 55 vs 53 Mar: 104 vs 103 Apr: 139 vs 139 In 1959, every month from May to September saw over 200 hours of sun, with May-Aug all seeing over 220 hours each.

Scorcher London is about 1c warmer than Edmonton for summer average highs (comparing airport to airport). Jun: 21.6c vs 20.7c Jul: 23.9c vs 23.0c Aug: 23.4c vs 22.4c

Yesterday was the first day to record 10 hours of sun since 14th September. That must be the longest ever wait between 2 such days?

Frigid That would rule out being able to enjoy the evenings if it got that cold at night. 14-15c low is ideal, that way it's still around 18-20c at midnight. I wouldn't consider June 2013, July 2011 and August 2009 particularly sunny either.

danm Cloud with sunny breaks would be mostly cloudy. I think of it as sunny, partly cloudy, mostly cloudy, cloudy.

danm What is the difference between mostly sunny and partly cloudy? Don't they mean the same thing?

A very average late April day today, partly cloudy skies and temperatures of 16-17c.

CryoraptorA303 Nope, there were 3 days in the final week with more than 10mm of rain each, with the wettest being the 23rd with 19mm. The month had 7 rain days which is about average for May. Compare that with May 2020, with 2mm and only 1 day with rainfall.

Scorcher May 2018 had 58.4mm here, vs 2.0mm in May 2020.

raz.org.rain We would need that summer 2022 repeat after a May 2022 if we were to have any hope at all of having even a remote possibility of normal sunshine levels for the year.
