UK Weather Trends #38 – Autumn 2025

December 3, 2025 By Nigel Marriott

The UK autumn in 2025 was warmer and wetter than usual but not exceptionally so and continues to be consistent with the step change in our autumnal climate seen 25 years ago.

UK Weather Tracker #105 – October 2025

November 4, 2025 By Nigel Marriott

Like last month, the weather in the UK in October was unremarkable.  I must confess I found myself noticing the cold more than usual but perhaps I was subconsciously noticing the lack of sunshine and the narrow range of temperatures as shown in my refreshed dashboard below?

UK Weather Tracker #104 – September 2025

October 4, 2025 By Nigel Marriott

After the hottest summer on record, the weather in the UK in September was unremarkable.  However, my local fishing club has just announced that a lake closed due to low water levels has reopened since water levels are back to normal so the above average rainfall in September has been welcomed in many areas.

UK Weather Trends #37 – Summer 2025

September 7, 2025 By Nigel Marriott

The 2025 meteorological summer in the UK was the warmest on record.  This came less from heatwaves setting new temperate peaks and more from steady warmth throughout June, July & August.  Overall it was sunnier and drier than usual in the UK but not to any significant degree.  As a result, whilst the 1st principal component confirms the summer can be regarded as a “good summer”, it was a long way from being an exceptional summer like 1976 & 1995.

UK Weather Trends #36 – Spring 2025

June 6, 2025 By Nigel Marriott

Spring 2025 in the UK was both the hottest & sunniest on record as well as the 5th driest.  For sunshine, 2025 was even more extraordinary than the exceptionally sunny spring in 2020 and was the result of 3 very sunny months in a row.  For temperature, there was no doubt in my mind this time the data was correct unlike last year when I questioned whether spring 2024 was in fact the warmest in record.  The Met Office has not corrected the record so apparently it was.

UK Weather Trends #35 – Winter 2025

March 5, 2025 By Nigel Marriott

Winter 2025 in the UK was unremarkable.  Last year I explained I believe our winters are following a steady trend to warmer and wetter winters which began in the early 1980s.  The data for the winter just gone doesn’t my conclusions.

UK Weather Trends #34 – Annual Temperatures in 2024

January 7, 2025 By Nigel Marriott

The 2024 calendar year was the 4th hottest year on record in the UK.  Last year, I used a Control Chart to conclude “a step change upwards (in UK temperatures) has taken place but the pace of change is not yet clear“.  I am now less confident in my conclusion after updating with 2024 data, especially when I look at temperature trends based on the meteorological year of December to November instead.

UK Weather Trends #33 – Autumn 2024

December 4, 2024 By Nigel Marriott

The UK autumn in 2024 was essentially unremarkable and mostly consistent with the step change in autumnal climate seen 25 years ago.

UK Weather Trends #32 – Summer 2024

September 4, 2024 By Nigel Marriott

The 2024 meteorological summer in the UK was unremarkable on all weather variables.  In fact 2024 was so unremarkable that it is in fact the most “normal” summer of the last 114 years when I compare the data to the last 50 years which I regard as “living memory”.
