They really should release the actual figures. The raw numbers that are displayed on their own website plus others like meteociel and weather online are wrong and misleading. Still don’t understand why they don’t, considering they show the actual ranges on the anomaly maps.

B87 strange why they don’t publish the true, corrected values…..

B87 thanks! Why does the Met Office not publicly display the corrected values? Or do they up to a certain year?

B87 an ok thanks. The thing is, on the met office and metociel pages they seem to have the raw sunshine totals, not the corrected values. Where do we see the corrected values?

Heathrow was 3 hours shy of the 1991-2020 average. I think we can probably call it an average year for sunshine!

B87 btw where do you get your annual and monthly stats from?

TwisterGirl81 5% either side of average is “about” average I suppose.

B87 I’m actually surprised we had 7 months out of 12 with above average sunshine in London last year.

To highlight Spring sometimes resulting in better weather in the west compared to the east (often due to the increased likelihood of northern blocking at this time of year, and easterly winds that favour the west more than the east), I checked the average sunshine totals for April versus July. In April, many western areas average a very similar amount of sunshine to the south and east: By mid Summer, the south and east averages significantly more sunshine than the north and west: You can also see this for Spring as a whole compared to Summer as a whole: This is largely down to high pressure being far more frequently centred to the north/NW or west of the UK during Spring than at any other time of year, which will always favours sheltered western and NW'ern areas. Add in a late season SSW that increases the chances of northern blocking even more, and this pattern probably becomes even more accentuated.

Yep that' possible. I was more referring to the month so far, which to date has run a little above average.

Maybe, but you did say that it's only been warm because of the mean so far this month, but we've actually run a little above average for max temps over the first 23 days of the month. Yes, that will likely drop a little as we get to the end of the month, so maybe finishing marginally below average.

You're right. It's no coincidence that the NW has their driest, sunniest weather between April and June, just ask @damianslaw.

Not sure you are correct with this. The average max temperature at Heathrow for the first 23 days of April 2024 is 15.2c against an average for the month of 15c. It's been chilly recently, but I reckon we could get into the high teens again next week. Here are the maxes so far in London this month. It's been dull and wet at times, but apart from the last week, it hasn't been cold:
