This was pretty exceptional for late September and the longevity of it makes it even more remarkable. 7 consecutive days of above 25C for some locations for the last week of September is astonishing.

When 1895 is ever mentioned this heatwave is totally forgotten and the freezing February is always remembered. A year certainly for the weather annals with a string of record minima in February and a string of record maxima at the end of September.

[Terminal Moraine]

It certainly was exceptional. Buxton had a max' of 26.3c on the 24th that month, the highest value for the last week in September on the entire record.

The nearest approach to such late September heat in recent times was the max' of 25.5c on Sept' 21st 2006 (25.0c here) but that was a one day only offer.

84F in Manchester on the 28th- that's incredible. I can't find too many examples in the records of 29C in Manchester in September at all, let alone in the last few days of the month.

That said, the figure clearly wasn't recorded at the airport which didn't exist at the time- could well have been in a more built-up area.

A much stronger heatwave than what we had last week considering it was at the end of the month.

38 minutes ago, The PIT said:

A much stronger heatwave than what we had last week considering it was at the end of the month.

I disagree, the CET for the 4th to 10th this year was 21.6C, which is a whopping 3.6C above the last 7 days of that September. Yes you'd expect the end of September to be cooler then the 1st/2nd week but not that much.

Absolute maxima was typically 2-5C cooler then the maximums we got this year.

Here is the CET data:

                         early/mid 2023   late 1895
Mean temp:    21.6C                    18.0C
Mean max       28.2C                    24.4C
Mean min       15.1C                     11.8C

I don't know how you can conclude the heatwave of 1895 was 'much stronger'?

Just for additional context, the 91-20 average CET for Sept 4th-10th is 15.0.

Whilst the average for Sept 24th-30th is 13.2C

Therefore the anomalies are as follows:

4th-10th Sept 2023 = 6.6C
24th-30th Sept 1895 = 4.8C

Incredible heatwave for sure, the max temps for the warmest places during that comparable to what Coventry had last week with the 29C to 30C!

Just goes to show there is still a lot of residual warmth to our south around a century ago well into autumn, and even more so in today's climate! Similarily the case with mid September 1926 or early Octobers of 1908 / 1921 and more recent ones of 1985 and 2011.

Incredible temps for so late in September. Particularly considering that it's over 100 years ago.
