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?

Pay Gap Data #8 – Where can I find gender pay gap data for 2024?

October 6, 2025 By Nigel Marriott

This post was updated on 6th October 2025.  The next update is planned for early January 2026.

The government requires nearly all employers with a headcount of 250 or more on their snapshot date to submit gender pay gap data.  All data is available to the public and can be found on the government’s gender pay gap website.  I have downloaded this data and created a spreadsheet to present the data in a more user-friendly and visual format.

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.

Stats Training Materials – Pay Gap Analytics

October 1, 2025 By Nigel Marriott

*** Updated with links B16 and P9, P10 and P11 for 3 presentations I have given recently on gender & ethnicity pay gap reporting.  I have also added new sections I & J**

The 5 steps to closing a pay and/or representation gap are –

  1. Define what success looks like i.e. where you want to be in the future
  2. Measure where you are today
  3. Analyse your data to understand why you are where you are today & what the key drivers are of your gaps
  4. Implement actions which move you from where you are today to put you on the path to where you want to be in the future
  5. Control the key drivers to ensure you are on the right track

All steps require the use of statistical thinking and statistical methods.  Other skills and processes are also needed but they cannot succeed on their own without the help of statistical thinking.

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 Tracker #103 – August 2025

September 7, 2025 By Nigel Marriott

It was the 8th warmest August on record in the UK.  When combined with the 5th warmest July and the 2nd warmest June, the result was the warmest summer on record.  Otherwise, the weather on average in the UK continues to be unremarkable in terms of rainfall and sunshine but that disguises some significant regional variations.

UK Weather Tracker #102 – July 2025

August 2, 2025 By Nigel Marriott

It was the 5th warmest July on record in the UK making it also the 5th month in a row where temperatures have exceeded the historical upper decile.  The weather in the UK continues to be unremarkable in terms of rainfall and sunshine but we are on track for the warmest summer and year on record.

UK Weather Tracker #101 – June 2025

July 2, 2025 By Nigel Marriott

June 2025 was the 2nd warmest June on record in the UK, just behind the record set 2 years ago.  Otherwise, the weather in the UK was unremarkable.

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 Tracker #100 – May 2025

June 6, 2025 By Nigel Marriott

The 2nd sunniest May on record in the UK follows the sunniest ever April & the 3rd sunniest March and resulted in the sunniest spring on record.  I am not surprised that in many regions it was also the warmest spring on record.
