Jesus Christ. This can't be real. You're trolling, right? That is definitely real. Now who's had it worse, London or Bunghole? Some recent months have been quite dull, but I've been taking a look at the sunshine stats at Heathrow and comparing them with others areas including Buxton. Certainly, we have had no such decrease in sunshi hours. In fact, if anything sunshine has increased here and elsewhere since 2011. I noticed that 2005/2006 was when LHR had a Kipp&Zonan sun recorder fitted, recording at the 120w/m threshold, after which the numbers are recalibrated to lower values corresponding to the old recording equipment previously used. It seems very suspicious to me that numbers have been consistently lower since this took place. I am wondering if the real issue is actually with the re calibration process overcompensating and nothing to do with it actually getting duller in London. |

Why does the 120W/m2 reading get downvalued instead of the old technology upvalued? I though the standard was 120W/m2 and if that yields more sun hours than your old measuring system, maybe your old system was "wrong". |

They must do it for consistency purposes.

B87 needs to get himself back out to Brisbane again, then he won't have to complain about how cloudy London is all the time.
My sister came back from Brisbane a couple of years ago, and the thing she struggled with was the cloud. Now she's back there, I doubt she'll ever come back, especially now she keeps having kids every 5 minutes.
It would make sense that there's an error somewhere, as London seems to be the only area that's been getting consistently below average sunshine readings. We've generally been fairly average here, but we have had some very cloudy months too.

I'd be inclined to agree. There seems to be some contention in the met office about what they consider "bright sunshine" it seems.

I wouldn't have thought that was the case personally. I did some working out between calibrated and un-calibrated K&Z sunshine hours at LHR and worked out the difference between them is about 13%. That would make 1600 hours on the old recorder into 1800 hours a year with the new one before calibration. I don't know what equipment Paris climate data uses and/or if it's re calibrated to any older standard. Looks as if it has to be. |

It isn't just a calibration error though (if there is one). Most summers since 2007 do feel much cloudier than those before. Pre-2007 summers would have lots of sunny or partly cloudy days, while post-2007 days have sunny mornings and evenings, but lots of cloud from 11am until about 7pm.
2013 and 2014 felt like typical summers as far as sunshine goes. 2017 had 90% of the average, but there was an extremely dull period from late July to mid August.
Some values recorded at the time (corrected value):
July 2006: 312 hours (268 hrs)
February 2008: 138 hours (130 hrs)
July 2013: 303 hours (266 hrs)
No complaints from me this month so far; we are well on course to end the month with at least average sunshine.
I think Paris numbers are from CS recorders, 1630-1650 in London vs 1660-1700 in Paris seems about right, there's no noticeable difference in sunshine between the 2.

London generally is a cloudy place all of Britain is. But can't tell the difference though the Spring seems awfully cloudy than usual....

(weatherbox coming in a few minutes) April was much colder and snowier than normal in Wisconsin, even with the last 10 days being average to above average and dry. Northern stations had snow on the ground for most of the month. A large storm hit Green Bay and surrounding areas in the middle of the month, with deep snow and strong winds. The largest snow total was 29 inches. Milwaukee: 5th coldest on record (-6.7F/3.7C) Madison: 2nd coldest on record (-9.0F/-5.0C) I added Green Bay since they had their snowiest April on record, by far. Green Bay: Snowiest on record at 36.7"/93cm, second place is only 15" Milwaukee: Well below normal, the first half of April felt more like March except for the sun angle. 18 of the first 20 days were 5+ degrees below normal, 12 of them 10+ below normal. The last 10 days were average and it got hot on the 30th to make the numbers somewhat respectable. 7 days with snow cover, more than March.  Madison: Similar to Milwaukee, but colder, even though Madison is usually warmer than Milwaukee in April. Only 0.1F from tying the record for coldest April from 1874. 7 days with snow cover. Wind chill reached 3F/-16C on the 7th.  Green Bay: colder than normal but not record-breaking. They got 24 inches/61cm of snow in one storm, with wind gusts to 51mph/82kph. Normal April snowfall is just 2.9". 17 days with snow cover.  *12 precip days, humidity 64% |

Thoughts on Gran Canaria and Lanzarote's climates then? Surely even worse than A+ La Laguna? |

Halifax looks terrible. Endless cold rain and barely any warm weather.
Vasilevichy had an impressive warm-up. April's coldest night is barely colder than the average March high.
