This is not necessarily about warmest or coldest extremes you've experienced, but rather the context under which crazy temps occurred! My three nominees are from the past few years that I've noticed since I became a weather geek: * 1 November 2014: The Örebro night recorded 14C on my thermometer at 3am. There were also insane thunderstorms, something I've never experienced past Aug 20 before * 26 August 2016: The mountain range had blocked the 32.6C late August Sweden record heat in Norrköping from crossing over to Nyköping during the day, but during the evening the hills couldn't resist. The 24C high here during the day had sunk to 22C after nightfall, when I went out for a bike ride on a rural floodlit bicycle track. As I re-entered town from the direction of the village of Sjösa, the warmest westerlies I've ever experienced under the night skies hit. As I went indoors and checked the temp I got a 24.6C reading at 10.22 pm (after 9.15 solar time) during a time of the year when the sun angle has sunk beneath 45 degrees, we nearly hit 25C during the actual physical night * 31 December 2016: New Years'e eve was wet and rainy. Nothing new there, except the temps. As the clock struck twelve it was 9C outside in the middle of the night with peak sun angle being at 8 degrees! So what about your weird memories of anomalies in temperature and those freak crazy standout moments, especially in seasons when these readings aren't expected?

9'C during the night isn't weirder than 9'C during the day on New Year's lol, something even we can manage.

Great thread idea! I'll let the pics do the talking.... a situation so epic that photographic proof is needed for it to be believed.

I'd never had it here before though, and also I've spent several years in the interior beforehand where that was unthinkable! 7C during the night I thought possible but 9C took the cake Earlier in December though before the solstice I've experienced 11C before at 11 pm when I was outside so of course things can happen, but normally cold sets in pretty hard after Christmas. What about this one though Baba, neither Nyköping or Örebro have had a New Years' Frost since Jan 1, 2010? Oh, by the way, didn't Umeå reach 25C at 9 am (prior to 8 am solar time) during the 2014 heat wave?

We've never had any kind of heatburst here and we don't get foehn effects, but one day when you looked at the temps and go "Wow, how the hell did that just happen?!" was 1st November 2015. Not only was it two whole degrees warmer than any other November day we've ever seen (18.2C), but completely unlike any other really mild November day I've seen it was clear blue skies from dawn till dusk with not a breath of wind - 2 pm and we almost had our summer temperatures with the sun only 16 degrees above the horizon, barely high enough to clear the trees. The very next month we broke our December record (14.3C) at 8 am on the 19th, i.e. before the sun even rose. That whole month was the most abnormally above average month ever seen in 350+ years of English weather records

Haha, don't know about the December one but what made the November one even sweeter was that east of the Pennines which usually hogs all the good weather around here missed out that day, they had thick fog and were 6-7C cooler than us for a change

Oh, by the way, didn't Umeå reach 25C at 9 am (prior to 8 am solar time) during the 2014 heat wave? I don't know. Possible. However, IIRC Umeå has had lows above 25'C either way. Holmön had a 26-something low once I believe. One of the strangest events I remember was a sunday. We'd had some frigid days at double digits below freezing. Our thermometer definitely read -18'C as we hit the bed the night before. As we woke up to walk the dog it was still double digits, but a couole of hours later it was raining as we drove to Ikea. The asphalt was still deeply frozen so some of the rain froze instantly upon impact, the rest covering the smooth ice with slippery water. My SO's stepdad was driving and pointed out how slippery it was. He said "I'm gonna try the brakes" but he never did. I asked him why he didn't do it and he said he did, only absolutely nothing happened when he slammed on the brakes. Mind you we did have studded tires. In the city there was chaos. People were driving at walking speeds all over, some cars simply sliding across red lights in intersections. I believe this is Umeå Airport's stats for that day. It later went on and hit 6'C that day.

Do it Beerman, you're in Australia mate Baba// SW foehn winds from Dalarna? That looks insane, first that low so late and then to recover and hit a normal April high the very next day! As for Holmön, well the all-time Swedish record hot low is 23.6C at Gotska Sandön (5 Aug 2014) so that's simply not accurate Possibly it was 26C at midnight during their first ever 30's day in 2014 but then it must've collapsed before 4 am.

12°C in December. I went shopping in a T-shirt and shorts out of spite.
27°C at night during the inferno of summer 2010. Sweat pouring all night, couldn't sleep right for most of that summer. The one after that was just as hot.
A cold wave ending in a single day with a high of 0°C after a low of -27°C. 0°C never felt so warm.
In recent years, the winter solstice has recorded temperatures higher than the summer solstice, twice. 5°C year round baby!

I'll post something different to Beercules. 29/12/2016 stats: Low/High: 24.9°C/34.7°C. Highest dewpoint: ~25°C Rainfall: 62.8mm At 3pm is when the dewpoints rose dramatically and it started pouring rain. I was in the subway, and my glasses were fogged + I was beginning to be short of breath. [Photo credit of the ABC, afternoon of 29/12/2016]

The 2C high and heavy snowfall on April 27, 2016 was also something special.
2010 was quite warm on this side of the Baltic as well, but nothing like on the eastern shore! Wow, it must've been insane! What was the hottest overnight low in Estonia that summer? Did it go higher than the 23.6C Swedish record at say Ösel?

Why can't this be the normal in Australia's best city? Melbourne can really turn it on when it wants to, as seen in the historic obs I posted.

Another couple, this time cold ones. I wasn't here at the time, but it's a place I know personally and an event I was keeping a close eye on at the time. Capel Curig in the Welsh mountains is known for very high rain totals but had never seen a temperature below -11.7C from when the weather station was set up until December 2010, but there it was, nearly -15C after midday Such a shame the cloud rolled in and the temperature rose after dark, because the Welsh record for the lowest maximum is only -8C, so this event could have absolutely smashed it. This one I was there to see in person, 24th March 2013 in Hampstead when the temperature was hovering around -1 to -2C in mid-afternoon with snow on the ground. That might not sound that cold, but the average there at that time of year is something like 12C and 5C in the afternoon in late March would be a notably cold day, ice days might not happen there for years at a time. Before 2013, the latest ice day on record in Hampstead was something like 7th March and that was way back in 1947. I genuinely expect every possible heat record in the books to be broken before anywhere in the London area gets an afternoon anything like that again in late March.

Just a couple that come to mind here... A heat burst in May this year saw a temperature of 34C at 2am at the Met Office station in Selmun. And a minimum overnight temperature on my PWS of 24.7C on November 8th 2016, especially when you see how cold most of the rest of Europe was that night. The minimum at Luqa was 23.7C:
