Scotland did last month, came close to breaking its all time record, it's lost momentum recently though.

Being near the continent has its benefits when the conditions align correctly. Although that quickly disappears as you head north. Does the UK get above average summers,with above average rainfall? August 1997 and July 2014 come to mind.

^Scotland seems to stand out as much as Scandinavia Scotland stands out in the second 500 hPa height map not the temperatures. Surface patterns or bring at the edge of the ridge kept Scotland cooler |

I wouldn't consider the July an an above average month for rainfall, but the August was -was that due to an increase in convectional rain, or an increase in rain bearing fronts? They both had above average rainfall and both were due to more convection and thunderstorms. Almost all precipitation in the summer here is from convection (excluding abnormal years like 2007 where the jet was out of position). The further north and west you go, the more precipitation is frontal vs convective. |

Whats affecting the environment here is the fact that there's not much storms with this heatwave. I just want it to cool down at this point.

Almost all precipitation in the summer here is from convection (excluding abnormal years like 2007 where the jet was out of position). I wouldn't consider 50mm vs 45mm as really indicative of anything unusual. You don't really get frontal rain during the summer? - do you consider the summer rainfall in London more typical of Cfa climates or Cwa climate? If 2007 had above average rainfall from systems, was it also warmer than average? 2007, 2011 and 2012 were cooler than average with frontal rain. Summer rainfall is more like Cfa than Cwa here. Usually pop-up showers or storms that don't last very long. Bands of rain sweeping across the country are more of an October-February thing. |

Both May and June had the warmest average high on record in Bingley, July's going to be just short. You need some proper heat (i.e. 28C+) in there to break our July record while we've just had lots and lots of 22-26C days. July will most likely have the most days over 20C in any single month on record (the current record is 25, while every day this month except two has been over 20C as well as every day in the forecast).
May-July will be very close to the sunniest three-month period on record here (a record set in 1911!), and probably close to the driest period as well. No water restrictions here thankfully, but there is going to be a hosepipe ban in the North West, even though that's usually a wetter part of the country.

May was the 3rd warmest on record at Heathrow, while June narrowly beat June 2017 into 2nd place (and was also the driest June on record).
No sun records falling yet, though might happen this month or August.

^^^ I guessed that would happen, the previous hottest was 33.1C in North Wales (foehn effect); that would be the hottest anywhere in the country in most summers and it did well to hold out as the hottest for as long as it did, but somewhere in the SE/East Anglia was always likely to beat that at some stage. That new record probably won't last long either.

Can see somewhere in London/Surrey/Kent hitting 35c+ in early August. If we got a strong southerly now it would be our best chance possibly for many years to have a go at 40c; the continent is baking and the ground is incredibly dry.

Lapland will see its hottest July on record. 20C means above the Arctic Circle...

Över-Kalix just above the arctic circle has averaged 26.8/11.9 so far, so 19.4 mean. No 20'C mean above the arctic here, but using our weird daily mean calculatiln they're at 19.9 up until yesterday. Are the Finnish 20'C means using your 24h mean or max/min? All days above 20'C so far for Överkalix. Umeå has missed out on two days.
Stockholm has had 6 days below 25'C. Arvika has had 0 days below 25'C, and Uppsala got 8 days in a row above 30'C.
Torpshammar at 62'N had 6 in a row and Överkalix in the arctic had 5.
Svenska högarna in the Stockholm archipelago had 5 tropical nights in a row during which they averaged 27.3/22.6 for a 25.0'C mean.

2007, 2011 and 2012 were cooler than average with frontal rain. Summer rainfall is more like Cfa than Cwa here. Usually pop-up showers or storms that don't last very long. Bands of rain sweeping across the country are more of an October-February thing. An interesting difference to my climate, where wetter than average summers are also warmer than average. Convection is common here, but mostly over the mountains, subtropical lows tend to bring heavy rain over short periods, rather than bands of rain. Does the summer high pressure zone prevent subtropical lows from bringing rain during the warmer months?Normally the southern half of the UK is influenced by the Azores high; the reason for the incredibly poor summers of 2007, 2011, 2012 was the jet displaced to the south, leaving us at the mercy of low pressure systems from the Atlantic (which would normally track north of Scotland).
Usually by September we can get ex-hurricane remnants causing wild fluctuations in conditions (as happened in late August/early September 2005).

Japan and Alaska are in a heatwave as well. It'd be cool to see a map of the northern hemisphere, looks like everyone is baking.

Lund had its 64th consecutive 20'C day today.
