On the 8th of August, Stockholm's 20'C Tx spree since June 2nd ended. A very long spree of โฅ20'C highs, but quite a bit shorter than the Swedish record from 2018 when some stations, like Lund, didn't record a single sub-20'C high between early May and late August which was insane.

Baba I think the Swedish record is higher than Milwaukee's record at 43N:
99 days from 6 June to 12 September 2012.
June of this year was the first to have 70F highs every single day with nothing below 73. 1973 and 2017 are the only two other years without a high below 20 in June. July and August have a mean coolest high of 66F/19C. May and September have never made it the full month.
However if you go inland those cool days in late spring are less common. Madison has a streak of 121 days, from 30 May to 27 September 2005. This summer has a streak going since 31 May.

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 theyโre 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 Total: 122.5 Are you able to do this for other locations? |

Are you able to do this for other locations? Not sure, the Fort Collins station has 10 minute data that you can easily download for long time periods. This site will do it for ASOS stations in like 30 seconds, not sure how accurate that is though. So basically, if you have a station where you can download 10 minute or hourly data for whole months at once I can do it. If not, try the IEM site. |

This is what that site has for Tucson Steelernation (number of hours with measurable precip): January: 26 February: 0 March: 9 April: 0 May: 0 June: 2 July: 51 August: 23 (so far) |

FUN FACT: Sydney's driest month is still WETTER than Melbourne's wettest ( Source: Weatherzone, Anthony Sharwood, Wednesday August 18, 2021 - 11:33 EST ) Melbourne is renowned for its changeable weather and people tend to think of it as a persistently wet kind of city, but as we've told you before here at Weatherzone, it's nowhere near as wet as Sydney in terms of total rainfall. Indeed, Sydney's annual average rainfall of 1213.4 mm is almost double Melbourne's 648.3 mm. When you measure rain days, as in, the number of days on which at least 0.2 mm of rain falls, the picture inverts significantly. Melbourne has 150.6 rain days compared to 143.2 in Sydney. So while Sydney has slightly fewer rain days, the rain that does fall tends to be a lot heavier. But there's another stat which emphasises the degree to which Sydney receives more rain than Melbourne, and that's the monthly rainfall totals. Incredibly, Sydney's driest month (September 68.1 mm) is still wetter on average than Melbourne's wettest month (October 66.0 mm). Yes, you read that right. Or to flip it round the other way, the average wettest month in Melbourne is still not as wet as Sydney's average driest month.  In case you're wondering, we were crunching rainfall stats today because it's mostly dry in all the capital cities (and pretty much everywhere in between) and we were wondering how often in winter you get a day with no rain in any of the capital cities. The short answer is not too often, but we hope to bring you the precise answer in coming days. Some parts of Australia are of course typically very dry or relatively dry by local standards in August. It's currently the dry season in Darwin, for example, with close to zero rainfall expected throughout winter, and an average of just 1.6 mm in August. August is also Sydney's fourth-driest month, with an average of 80.2 mm in the gauge And August is Brisbane's second-driest month, with an average of 35.4 mm. But Perth, Hobart, Melbourne and Adelaide all experience on average at least 15 rain days in August, when the ground is at least a little bit wet at some point during the day. Canberra also has around 10 rain days in a typical August. So for all eight capitals to go rain-free on the same day in the month of August is pretty unusual. Wednesday August 18, 2021, looked like it would be such a day, but that's no longer the case after 0.4 mm of rain was recorded in Melbourne. |

I created a tropical index formula to make it simpler and more effective to distinguish tropical from non tropical climates:
Tr_Ind = (T_wdew*10*Cos(Lat)/T_sdew)+10.
Lower the difference between summer vs winter dew, and lower the latitude, it's more tropical. Also, no need to use absolute values for Latitude (the amazing thing about using Cos). Also, my formula can also be used as a rough estimate for continental index (but it wouldn't be ideal), it would just be 100/Tr_Ind.
Just as an example, Mumbai would have a value of 15.5, NYC would have a tropical index value of 8, and Anchorage would have a value of 3.
Conversely, the estimated continental index would be 33.3 for anchorage, 12.5 for NYC, and 6.45 for Mumbai.

Looks like our limp-dick max of 22.6ยฐC this Poorgust is actually a century-old record or some shit LMFAO.

22.6C is their highest temp recorded this month, not the average high so far...
Mine is 24.7C, Gayba's 23.7C and Babu's 22.8C. So pretty shitty all around.

For all of August so far? Brutal. The mean August maximum in those places is what, 5C higher than that? |

Yup.
Yeah, since 2003 for my place, the median highest temp you'd expect in August is 28.9C.

God only knows what's happening this year. Seems cursed or something. Yep 22.6ยฐC the "warmest" day of the entire month. |

Been playing around with HighCharts recently, I plotted a heat map for visualizing hourly temperatures at my PWS since May 6th (when I put my WeatherLink unit into use; yes, there's a heat map canvas here, I made some adjustments, such as the color scale, and I'm using ยฐF for clarity) up to yesterday.  May  June  July  August (blank spaces for the 2nd is because of data loss due to a power outage  )  Some notes and tidbits: 1. I deliberately excluded data for June 20th-24th during my trip to Sicily, as mentioned earlier. 2. In the all-time heat map, you can see that towards the end, 8 AM and 8 PM temperatures blend more with nighttime temperatures thanks to shorter days. 3. The afternoon of July 18th is the only daily low occurring in the afternoon for the period. 4. Many of the temperature fluctuations in evening/early morning hours appear to occur with other nearby PWS'es, even if PWS unit isn't ideally placed (too near concrete and near the top above a nearby gully). |

Six Irish people, all of whom are now safe, were in distress in the eastern part of Kebnekaise's southern peak on Monday morning. One of the people was wearing shorts and according to the police it was minus ten degrees during the night.
The police received the alarm early on Monday morning.
- There are a total of six people involved, all from Ireland. They are stuck and do not get up or down, said Bjรถrn Pettersson, RLC officer, at the police command center at 06 o'clock.
The police helicopter and the alpine group rushed to the scene.www.svt.se/nyheter/lokalt/norrbotten/sex-irlandare-fast-pa-kebnekaise-tar-sig-varken-upp-eller-nerthat's a smart move.

Mine is 25.3c, with an average max of 22.4c for the month so far. Definitely the worst August here since 2015 (2017 averaged 22.0c, but was drier and sunnier). |

In addition, if any of you would like to check out the JS, HTML & CSS code itself, here you go: jsfiddle.net/0xs7zda1/Maybe timezone shouldn't be UTC, but I don't see how it matters tbh, because timezone isn't shown in final chart |

Same deal for dew points (I should add that maybe nei and tommyFL would find these, and temperature heat maps interesting?) jsfiddle.net/9xkgj501/1/ May  June  July  August (once again up to 22nd for consistency's sake)  While daytime dew point drops are more likely to occur with high pressure in place (thus, better subsidence and mixing), but a clear pattern emerges: dew points almost always rise after sunrise, even though the rise is amplified by plant transpiration to some extent (rarely more than by 2-3ยฐF though). Not as defined after sunset, but as you can see, dew points often drop after sunset, even with light winds. I wonder what the cause is, maybe partly cold-air drainage? Interesting how there's a "dividing line" in early June where before that dews remained in the 40s/50s, but afterwards they mainly stayed in the mid-upper 50s and 60s. |
