Seemingly, October 2025 in Warsaw appeared to be a cold and depressingly autumnal one. In fact, temperature-wise it has been perfectly normal, with mean temperature of +8.7C, exactly at the par with long-term (1991-2020) average. Perception of many has been shaped by a series of eight warm Octobers in a row between 2017 and 2024, with mean monthly temperatures ranging from +9.6C (2021) to +11.3C (2019).
The recent October was indeed a rainy one, with monthly rainfall totalling to 68.7 millimetres, vs. long-term average precipitation of 40.2 millimetres The blessed rain (171% of long-term average) has been a drop in the ocean in terms of solving the problem of drought, but we are keeping fingers crossed for next wet months, preferably for a snowy winter. Of note are thunderstorms with heavy, yet short downpours which smashed Warsaw on 26 October 2025 and 30 October 2025. Such phenomena happen very rarely at this time of year.
As the October was rainy and cloudy, temperature fluctuations were low, hence cold afternoons were offset by warm nights and mornings.
We had two frosty days in October (note the absence of sub-zero temperatures in 2017, 2018, 2020, 2022 and 2024), with the first frost being the earliest since 2001. Month-time low of -1.2C was measured on 3 October 2025. The first days of the month were some 5 Celsius degrees colder than long-term average for those specific days.
Month-time high of +18.9C was reported on 23 October 2025, during a short spell of golden autumn. It was the first time since 2010 when the maximum temperature in October was lower than +20C.
Forecasters claim early November will be making up for the lack of above-average temperatures in October, but what is seen in the weather predictions by no means extraordinary for this time of year. In the benchmark period of 1991-2020, the average November's highest temperature stood at +14.8C.
To refresh
your memory, in recent two decades we had several spells of November warmth:
+15.5C on 8 November 2022,
+16.0C on 3 November 2020,
+16.5C on 4 November 2019,
+19.2C on 2 November 2018,
+15.8C on 8 November 2015,
+18.6C on 6 November 2014,
+15.7C on 3 November 2013,
+17.2C on 14 November 2010,
+16.9C on 1 November 2008.
