Ugh there's lots of convection around today but just too far from here to hear any thunder, apparently Sheffield had thunder earlier but I was inside and it wasn't loud enough for me to hear it so that's annoying too. Hope something else forms this afternoon close enough to be worth it.

I meant like for Asian standards, it's not that far off from a body of water -- in its case, the Mediterranean Sea (although I know that the Med Sea is pretty warm itself). I mean, I would expect such high temperatures in say Central/South Asia at the same latitude. I don't know?  Let's compare it to Wilcannia in NSW, which is 600 km inland on both sides (east and south), except it's 7C cooler in the summer (on average). I just never saw Duhok to be "normal" for its latitude. en.wikipedia.org/wiki/Wilcannia#ClimateWell, the ocean that's near (in a relative sense) Wilcannia is much colder than the Mediterranean, so there's that. Also, Australia in general seems to have rather cool summers for their latitude. Central and south Asia at the same latitude is generally at much higher elevation and much farther away from a scorching desert. You make a point. I'm guessing my thinking is too "Australian-centric" even when it comes to international climates. So such hot temperatures at 37'N would be a shock to me, especially when places here at 37'S are, well, those little "summer-less oceanic hellholes" we call Melbourne and Auckland. Lmao.  |

Weather Underground's forecast for Grise Fiord Airport (76.43N) is actually a forecast for Iqaluit (63.76N). Candleur pointed it out. "shit site" indeed. 1500km/932 miles away. Notice the 63N at the top, even though current conditions are reasonable. It's 7C/45F in Iqaluit now, with 9-14C highs (48-59F) coming up.  This is the actual forecast for Grise Fiord. 1/1 and snow tomorrow  .  |

Makes sense for a small geographic area, but I wouldn't think it'd be an effective way to combat drought over that large of an area. |

Duh, mostly humid continental. Coastal regions are warm temperate, with even a couple oceanic spots. Yes, coastal areas do generally receive more precip than inland ones, but that’s because they get more precip in winter, spring, and fall. Also of course elevated areas are the exception as they get more precip due to lift. Summer precip is generally more even across the region. Obviously there’s no dry season anywhere and everyone knows that. The US northeast, especially the coast, is likely one of the places in the world with the least seasonal precip variation (other than bone dry deserts that get literally none most years) |

I don't know why I've never thought to do this earlier: to look at sun hours and sun percentage only during daytime (06-20 CEST, which equates to 07-19 in winter). This makes a fairer comparison of how sunny a place actually is since it both eliminates sunshine recorded during the night while you're sleeping, in the far northern places, as well as eliminating terrain obstruction and general difficulties recording sunshine near the horizon. It could probably be expanded to 22 as well to make it 16h of daytime and 8h of nighttime, but this increases factors such as terrain obstruction etc. For example, during 06-20, Umeå recorded 79.5% sunshine in May 2018. Meanwhile Svenska Högarna in the outer reaches of the Stockholm Archipelago recorded 89.5%. In fact, Svenska Högarna recorded a 80.0% sun percentage for the whole May-Jul period (06-20). I'll compare five stations, Luleå (65.6'N), Umeå (63.8'N), Svenska högarna (59.4'N), Karlskrona (56.1'N) and Lund (56.7'N), from 2010-2020 (the period in which all the stations have been co-active)
| Total | 06-20 | | Luleå | 1962 (#3) | 1736 (#4) | | Umeå | 1918 (#4) | 1760 (#3) | | Svenska Högarna | 2219 (#1) | 2065 (#1) | | Karlskrona | 2152 (#2) | 2024 (#2) | | Lund | 1800 (#5) | 1687 (#5) |
Lund still remains the cloudiest of the bunch, and Svenska Högarna the sunniest when using only sun during 06-20 CEST, but Umeå and Luleå suddenly switched places, and while Luleå is 162h sunnier than Lund in terms of total sun hours, they're only 49h sunner "during the day". The difference between Svenska Högarna and Karlskrona also decreases marginally. And while Karlskrona is only 9.7% sunnier than Luleå in terms of total hours, they're 16.6% sunnier when only comparing daytime. This method could also be used to compare places where there's suspected terrain obstruction, like in Norway. |

Umeå has digitalized sun data since 2008. Here's the monthly sun percentage for 2008-2020 during 12-14 DST, i.e. three hours each day centered on (approximately) noon which are physically able to record 100% sun hours on any day of the year.  Using the exact same hours in Lund gets us these values:  But since Lund has longer days in winter (7h vs 4h at winter solstice) we can afford to use 5h instead of 3h for better data size and better representation of noon sun percentage.  What's interesting is that since Umeå is more coastal than Lund, you're expect the coastal sunshine benefit during noon to be the strongest in late spring and early summer when the sea is colder than the mainland (reduction of cumulus clouds due to sea breeze etc.), but when comparing Lund and Umeå, we see the opposite. Lund is cloudier than Umeå the most in fall and winter, and barely even cloudier at all in late fall and early summer. If anything, Umeå is actually cloudier in Apr-Jun when you'd expect Umeå to be the sunniest. This is of course only noon-time data, and it's also only a 13 year time period so a lot of this could just be due to data noise, but still interesting imo. Here's Borlänge, one of the most properly inland sun stations we have that isn't in the Scandes mountain range or the rainy south-Swedish highlands (3h centered on noon). Clearly the sunniest in winter and cloudiest in summer of the bunch.  |

Norway's sunshine data is absolutely trash, especially when it comes to hourly data. Trondheim, Bergen and Oslo all seem to have pretty continuous data since 2016 available at least (Bergen Flesland had an October and November missing, and Oslo had one June missing), so here's 3h noontime sun percentages for 2016-2020, compared with Umeå to the right. And I did check Jan/Dec to make sure that all of the three hours included were capable of recording sunshine for the full extent.   The last five years, Trondheim has been 9.8% sunnier than Bergen airport at noon, which infamously averaged 1187h annually for 1961-1990. A five year time period is obviously way too short to draw any significant conclusions recording sunshine though, and noon-time sun percentage doesn't necessarily equate to actual sun percentage (noon can be cloudier or sunnier on average than mornings, afternoons, evenings etc.) If we assume 100% sun percentage would equate to 4500h of sunshine then we can compare how representative the total sunshine recorded is of noontime sunshine, using sun percent at noon.
| Noontime extrapolation (h) | Recorded total sunshine (h) | Difference between noontime and total sunshine | | Umeå | 2016 | 1968 | 2.4% | | Trondheim | 1851 | 1609 | 15.0% | | Bergen Flesland | 1685 | 1584 | 6.4% | | Oslo | 1981 | 1843 | 7.5% |
What we can see here is that for the last 5 years, Umeå's recorded sunshine totals have been the most representative of noontime sunshine, whereas Trondheim's sun totals have been the least representative of noontime sunshine. Whether this is due to terrain obstruction or because Trondheim is sunnier around noon on average compared in the mornings, evenings etc. is hard to know for sure. Another factor, that I didn't take into consideration initially here is I'm using sun percent on an annual basis and not a monthly basis, and since there are daylight hours in summer, sun percent is weighed higher in summer than it is in winter when it comes to the annual total. Trondheim sees a much smaller difference in sun percentage between summer and winter, which means that even if they had the same annual sun percent, they'd still record less sun hours. |

Q. What's worse than an ex-partner?
A. An ex-thunderstorm. We had one earlier. A Nothunderstorm, Shower, Blunderstorm, Dry Wank, Cumulonimbus Extinctus, or whatever you want to call it.

Any places in Australia, besides Telfer, that have average maximums of 40C+ in the summer? You mean all three summer months together or just one or two of the months ? Anywhere in the Pilbara, Gascoyne, Kimberley etc ( at low altitude ) probably averages 40c in at least one of the high sun season months. As does Birdsville in the Simpson, in January. Fitzroy Crossing in Oct and Nov averages +40c. Marble Bar Nov, Dec and Jan +40c averages. Gascoyne Junction in Jan +40c av. Emu Creek Station ( Nyang ) Dec, Jan and Feb +40c ( well 39.9c in Dec actually ) Paraburdoo and Pannawonica +40c Dec and Jan. Even Wittenoom at 463m averages 39.8c and 39.5c in Dec and Jan. Wyndham, coastal north Kimberley averages 40c in December as does Curtin Air Base inland from Derby. |

Fyi, that 42.6 °C record in Lingen has been discarded by the DWD. The new heat record is 41.2 °C measured on the same day in Duisburg and Tönisvorst. |

Latvia's record high is 37.8C, recorded in Ventspils in August 2014 IIRC.

Thanks for these locations btw.  |

Took a quick look at sunshine in Norway this year, and in Kristiansand, the sunniest place in Norway, March was sunnier than May, and in Bergen, January was sunnier than March. Almost everywhere, April was the sunniest month.  |

Here is the number of rain hours per month so far this year in Fort Collins.
Method is every 10 minute observation with precipitation is added and then they’re divided by 6 to get hours.
January: 6.0
February: 10.8
March: 24.5
April: 18.5
May: 51.3
June: 4.7
July: 6.7
August: 5.2
Sept: 4.2
October: 4.5
November: 4.3
Total: 140.7

Boregust is certainly turning out to be a grotty month here. Not concerned about the temps but for my outdoor hobbies such as cycling, it's been a nuisance with extremely poorly forecast rainfall amounts/timings, and where I live are plenty of very steep hills which can be pretty lethal when damp especially the busier ones. 15-20 degrees is great for outdoor activities so no complaints about temperatures, but what does it take just to get a dry week in summer?
