I'm amazed they haven't done anything about having an under-reading sun recorder at Heathrow then. Not very professional. You'd think they would correct the values before publishing them! It does mean that a few Augusts have been near average or sunnier than average since 2005 though, such as: 2007: 213.5 hrs 2012: 203.2 hrs 2013: 219.7 hrs 2014: 204.2 hrs 2016: 222.5 hrs 2018: 202.6 hrs 2019: 222.3 hrs Also, the mystery sunny July with over 300 hours on the Met Office regional climates page appears to be July 2006, 302.2 hours. |

What are these "corrected" figures you're talking about @b87 ?

What are these "corrected" figures you're talking about @b87 ? They are the ones I received in response to my email to the Met Office. They certainly make more sense than the raw, under-reported values they publish. After correction, London's sunshine totals are comparable to Paris' once again, rather than being out by 300 hours every year. The annual totals go from 1633 hours for 1981-2020, to 1676 hours for 1991-2020, in line with the rest of Europe. |

I don't know how they were corrected, but the issues started when the sun recorder was changed at the site. The Met Office raw data page says the values are uncorrected.
It has to be the sunshine recorder, as the UK overall has seen increasing sunshine (as has the rest of Europe), and it doesn't make sense for one station only to consistently under-report.
"All data values are subject to Quality Control (QC) processes. This means that data may be subject to QC related changes for periods of up to twelve months from initial capture. Data provided by the NMLA has been subject to a level of processing and may therefore vary from raw Met Office data available via other sources."

Nice one, did you get any other information from the met office? I assume they are not going to update on the actual page and if you want corrected figures going forward we have to request these? What was the change for 18/19/20 figures before and after? I have to say I thought something was up, days that were totally sunny in mid summer recording 12 hours only was strange Edit - just seen the raw data which is incorrect and yeah there are some quite major changes, have to say the weather box looks more accurate now to me.. |

Rapa Iti, one of the southernmost islands in French Polynesia. Actually quite cool year round, but still barely qualifies as tropical.  |

The first five's diurnal ranges are crazy, especially badiruaguato or whatever the fuck its called. Wtf do they put in the soil there. How can you have a desert's diurnal range in summer when its so fucking rainy. Worse than central cali maybe.

LZ40, a platform in the middle of Lake Okeechobee here in Florida. The station doesn't record precipitation, unfortunately.  |

Station 41010, a buoy located 120 nautical miles off of Cape Canaveral. Sub-hourly data goes all the way back to the 1980s, but it's very time consuming to work with so I only included the last 10 years. www.ndbc.noaa.gov/station_page.php?station=41010 |

tommyFLI'm assuming that 96F high has to be some sort of error.

tommyFL I'm assuming that 96F high has to be some sort of error. I thought the same thing at first, but everything seems to make sense. It occurred on August 22, 2016 at 14:50 hrs. An area of high pressure had set up off the Southeast US, causing very hot temperatures in all of the coastal cities I've looked at from FL to SC during that time. If you look at the observations in the link, wind speed dropped to almost zero at the buoy, which allowed for the very hot temperatures. This area is borderline Sargasso Sea, which is prone to periods of very calm and clear weather. www.ndbc.noaa.gov/view_text_file.php?filename=41010h2016.txt.gz&dir=data/historical/stdmet/ |

Helsinki Airport sunshine. Data before Nov 1998 is unavailable.
Change from 1981-2010,
Jan: -2 h
Feb: -9 h
Mar: +23 h
Apr: +7 h
May: +14 h
June: +17 h
July: -5 h
Aug: +14 h
Sep: +13 h
Oct: +/-0
Nov: -4 h
Dec: -4h
Sunniest and cloudiest since 1991,
Jan: 57 (2014), 14 (2001)
Feb: 155 (1991), 19, (2014)
Mar: 252 (2013), 35 (1992)
Apr: 290 (2004), 94 (1992)
May: 408 (2018), 229 (2005)
June: 365 (2020), 188 (2014)
July: 405 (1994), 221 (2004)
Aug: 363 (2015), 108 (2008)
Sep: 234 (2000), 92 (2010)
Oct: 174 (2015), 31 (2006)
Nov: 57 (2004), 12 (2000, 2014)
Dec: 49 (1995), 5 (2012)
Was there some extraordinary event in March-April 1992 because those are some remarkable records? 2nd gloomiest since have been 87 h in March, and 151 h in April. The data is correct, as other stations have similar stats.
Or maybe there was just persistent low pressure like in August 2008, which was the gloomiest summer month in London as well. 2nd cloudiest was 171 in 2017.

Uppsala A 2018-2020  Oslo Blindern 2018-2020  Two Csb/Dsb
Those aren't Csb or Dsb. Both have both their driest and wettest month in the high sun period.

Doesn't matter. Technically a place can be csb and cwb at the same time. Cswb maybe? The s classification only requires that the driest high-sun month has 1/3 the precipitation the wettest low-sun month and less than 30mm. If March is 10mm, April 10mm, September 60mm and October 30mm, that's both s and w at the same time technically speaking. |
