I've noticed the Guy isn't re-posting extremetemps, so I was wondering why.
Didn't find an answer, but I found this.
October 2025 was the planet's third-warmest October on record » Yale Climate Connections
Only October 2023 and October 2024 were warmer.

October 2025 was Earth’s third-warmest October in analyses of global weather data going back to 1850, behind only 2023 and 2024, said the European Copernicus Climate Change Service on Nov. 7. The service rated the year-to-date period of January to October the second-warmest such period on record, behind only 2024.
The service reported that 2025 is likely to end up as the second- or third-warmest year on record, possibly tied with 2023 as the second-warmest year (behind only 2024). Because of the U.S. government shutdown, data from NOAA and NASA is not yet available for September or October.
This is the fifth time in a row that a calendar month has placed third for all-time warmth behind 2023 and 2024. While “third-warmest” may not sound eye-poppingly impressive, this comes on the heels of an astoundingly warm couple of years that were fueled by a strong El Niño event atop long-term human-caused warming.
Global October temperature classification. It was the 3rd warmest October on record (2024, 2023). 61% of the globe is in some shade of red; while only 13% is in some shade of blue. — Climatologist49 (@climatologist49.bsky.social) 2025-11-05T06:33:14.733Z
...According to NOAA’s October forecast, weak La Niña conditions are expected to prevail during the upcoming Northern Hemisphere winter, with a 55% chance of transitioning to ENSO-neutral in January through March 2026. The Oct. 20 forecast from the Columbia University International Research Institute for Climate and Society gave a 50% or greater chance of La Niña conditions lasting through December 2025 through February 2026.
Both of the forecasts above project the odds of El Niño to steadily climb to around 30% by next summer. Notably, the North American Multi-Model Ensemble suggests that sea surface temperatures could be above average, pushing toward borderline El Niño warmth, as soon as next spring (April-May-June). All six of the NMME’s component models now show this trend. With this in mind, it’s worth keeping an eye out for a potential El Niño event in the latter part of 2026, although it’s far too early for a reliable forecast.
