It's bad when 11 of the 13 days so far have been below average.

The monthly average high for Heathrow and Kew is 23.5c, but that is for the month overall. 1st July averages about 22.5c, with 31st July around 24.5c. The warmest part of the summer is the last week of July and the first week of August.

The warmest day at Heathrow all month was 23.6c, which is 0.1c above the monthly average. 11 of the 13 days so far have been below normal, with 2 even below 20c! Usually July gets a couple of 30c days, it won't this year. The long term average is 4.5 days above 30c per summer, but look at the last 2 decades. 2007-2016: 21 days >30c 1997-2006: 48 days >30c

I'm complaining because it's been a poor summer, as have about 7 of the last 10.

It ranges from about 22.5c at the start of July, to 24.5c at the end of July, so these 22-26c days in late July are not a warm spell at all, they are just the normal conditions. What would calm everyone down, would be a settled few weeks with highs of 25-32c or so.

The average max temp in London for mid-late July is 24c. Most of the models are showing 22-26c down here, so not much of a hot spell.

Would like to see a 'warm spell' bring something a bit better than just average, though. Is there any sign that we might get some proper heat, or has that disappeared now?

What's all this talk of amazing charts this morning, showing what is essentially average conditions for July?

The values on that link have already been corrected to CS values, even though they have been recorded with a KZ since 2005. July 2006 recorded 302 hrs with the new electronic sensor, but that was adjusted to 260ish so it could be compared to the older data. Same with Feb 2008 (138 to 130) June 2012 (130ish to 118.5), July 2013 (300ish to 266). I think they should show the new sunshine figures alongside the old ones; the rest of Europe uses the 120W/m2 standard. I think our sun hours would be about 13-14% higher in summer, and 5-10% higher in winter, using the KZ (threshold 120W vs the CS threshold of 140W). Maybe the regional maps are using the data from the KZ (which gives higher values), but then comparing it against the CS average? That would explain why the values are close to normal rather than below average. If you look at the sunshine section of the Southern England summary, the Heathrow graph shows about 130 hrs as the June minimum, and 302 hrs as the July maximum (both of these were recorded with KZ and since been downgraded to fit in with the CS).

I use the data from the historic data page rather than the regional summaries, as it is more accurate. Other areas in London and Surrey have definitely seen a massive decrease in summer sun since August 2006. the only summers to see sunshine above average since 2007 were 2013 (625 hrs) and 2014 (650 hrs). Heathrow's summer average is 621 hrs. All the others ranged from 470-560 hrs.

Southerners also have a higher expectation of what summer should bring. 20-21c in July or August down here is considered poor. The south suffered the most in June, with record cloudiness (Lerwick had double the sunshine of London).

We had 49% of our average June sun hours here, comparable to the list of French locations.

It's been cool and very cloudy down here too. It's not just the north.

The moaning comes from the fact that 8 of the last 10 summers have seen well below average sunshine in these parts, coupled with suppressed temperatures in July and August. Of the last 31 summer months, 6 have seen average or above average sun. Summer is not about 21c highs with 160-170 hrs sun (and even worse in the rest of the country)!

Yes, but the first half of September only averages 20-22c so a warm spell is just going to be like a slightly above average week in July or August. I don't get how it can be so difficult to get average sun hours in June-August, along with some normal temperatures rather than the constant 20-22c and cloudy rubbish we've seen. 1st June 2016 had a high of 13.8c, cooler than the start of December or February! I still haven't even seen 27c yet this year, and it's mid-July! I've only had 3 days of 25c too, which is just shocking.

Disappointingly average? If the summer had been average so far, you wouldn't be seeing so many complaints. It's been cooler than average and extremely cloudy. I see once again that any hint of some normal summer weather is fast going down the drain on the latest runs.

Seems like the models are reverting back to the below average temperature/extremely cloudy pattern that has plagued us for the last 6-7 weeks. Are we ever going to see our normal summers back? Surely it can't be too much to ask for a summer to have average temperatures and sunshine?

An average forecast for probably the first time all summer!!

Because even in a normal year we see 30c around 4 or 5 times. This year we haven't even seen 27c yet. 25c would be good, if it was recorded regularly like it should be, but we've only seen 3 days of 25c this year!

To match the long term average, August would need to average 31c, which is 4c warmer than August 1995!. To match the long term average sun hours, August would have to record over 650 hrs sun, which is impossible!

Even if we had that, August would be below average for the 2007-2016 period!

Really need some 30c days to make up for June though. They've been lacking a lot in the last few years. 2007: 0 2008: 0 2009: 4 2010: 2 2011: 2 2012: 2 2013: 6 2014: 1 2015: 3

Looks like we will see some average July conditions next week :o Highs of 22-26c, with 6-9 hrs sun per day.
