The 104°F high from September 7th, 1946.
There was only one other 100+°F high on record in September in Rome (a 101.2°F high set in September 4th, 1982), nearly 3°F warmer than the second hottest day on record for September, and the second hottest temperature for that day is a 94.3°F high set in 2008, that's an amazing 10°F gap between the hottest and second hottest day for September 7th!

27.8C (originally recorded as 82F) at Sumburgh in the Shetland Isles on 6th August 1910 when some warm air originally from SE Europe was advected across the North Sea via Scandinavia. Baltasound (also in the Shetlands) recorded 25C the same day but the Sumburgh site hadn't seen a temperature of above 21C/70F since at least 1871.
To make it even stranger, nowhere else in the UK reached over 20C that day at all, not even the Orkney Islands 100 or so miles south of Shetland.
It sounds VERY hard to believe, but apparently it's considered to be true.

It sounds VERY hard to believe, but apparently it's considered to be true. WOW! That's impressive. That's also over 4'C higher than the all-time record high in Lerwick, also in the Shetlands. Why was the warm air so concentrated over the Shetlands as opposed to also reaching the Orkneys or the Scottish mainland? |

Why was the warm air so concentrated over the Shetlands as opposed to also reaching the Orkneys or the Scottish mainland? Just a thin slither of warm air being sent west from Norway I guess. I don't know if foehn still has an effect that far from the Norwegian mountains as well because that would make 28C sound more feasible, but I can't explain why it was so far above the Lerwick record of 24C and the Baltasound record (other than that same day) of 25C though. Wick, one of the nearest mainland towns to Shetland, had a high of 58F that day so obviously under a completely different airmass. It's not actually that unusual for the Shetlands to be the warmest place in the UK in winter when the rest of the country is getting its weather from the east and Shetland is getting Atlantic fronts. It seems to happen in summer maybe once every 20 years or so when every factor you need lines up perfectly, so it is possible. It's just the 28C itself that sounds really dubious, even though apparently it's been investigated properly and it's supposed to be legit. Some talk about it here: www.ukweatherworld.co.uk/forum/index.php?/topic/50639-6th-august-1910-28-deg-c-in-shetland/ |

Our most impressive has to be Feb 17th 2016, high hit 32.2°C, 10.5°C above average, and our earliest 32.2°C+ high ever

Whiskeytown Reservoir is a station in the mountains west of Redding at 1300' elevation. On September 6, 1988, they got to 120F (49C).
Might be an error, since Redding and Red Bluff only got to 102 that day. However they saw 116 and 118 respectively on September 3-4. NWS shows a 120 for Whiskeytown, while WRCC shows a record high of 114 (WRCC records are sometimes wrong, however).

Darwin, Northern Territory.....the coldest April day on record and not far off the all time coldest day of 21.1c July 1968. At the latitude where temps are remarkably uniform and there is very little deviation from the average, April 11, 2017 saw a top temp of only 21.9c ! And mid afternoon the temp dropped as low as 18.3c. The top temp of 21.9c was 11c below the norm for April. All sorts of dusty, mouldy coats and jumpers were dragged out of the bottom of wardrobes and suitcases on this day.....the coldest day I have experienced in 40 years here in the deep North.   |

5 days over 38C since Dickcember 1. That's 5 days in 2 months at 34*S at sea level in Australia at the edge of a subtropical desert.
Remarkable.

Eucla, Western Australia reached a record high of 49.8C on 19th Dec 2019. The average December high is 25.7C.
I think this could be the largest difference between the average high and record high in a summer month anywhere in the world.

Fargo, ND hit 100°F (38°C) on April 21, 1980. The average high there on that date is 59°F (15°C). I don't think there are many places that have hit 100 when the average high is that cool.

102F (39C) here on September 2, 1953. What makes it even more impressive was that yes, while it is the latest 100 ever here, September 1953 was actually below average temperature-wise. Also July 5, 1999 recording a 86F (30C) minimum is quite epic. Even non-UHI locations recorded lows in the 80s during that heat wave. Christmas Eve 2015 was epic here too, with high/low of 72/63 (that one at Central Park).

The highest minimum record of 28.3C set in July 1936. Have not even come close to bettering it since then. The second highest minimum is 24.4C which happened 4 seperate times June to August.
(have not checked the downtown station though which has been operating since 1999 and has the warmest lows)

jetshnl The 1930s are good for having produced some seemingly unbeatable temperature records - the 99 F and 101 F record highs for May 31 and June 1 respectively are from 1934 and seem to stick out above the rest of the crowd, and our all time record (104 F or 40 C) was set on 13 July 1936. Those Dust Bowl era heat waves could be intense!
