Anticipated Autumn Temperatures in Siberia Could Break 30-Year Record for Warmth According to Weather Experts
Autumn 2025 is shaping up to be an unusual season in Russia, with forecasts predicting warmer temperatures and increased precipitation in several key cities. According to Yandex.Weather, the autumn could be the warmest in the last 30 years in Krasnoyarsk, Omsk, and Novosibirsk.
In Krasnoyarsk, precipitation could be the wettest in the last 5 years, with November's rainfall expected to be 1.5 times more than the average of the last 5-10 years and twice as much as in 2024. Similarly, November in Novosibirsk will see significantly higher precipitation than recent years, and twice as much as in 2024. Autumn precipitation in Omsk will be slightly wetter than last year but within the norm.
While the first snowfall in Krasnoyarsk, Omsk, and Novosibirsk is expected to occur at the intersection of October and November, the exact timing is not specified. However, it is worth noting that autumn precipitation in Omsk will be slightly warmer than the climate norm, making the first snowfall an interesting event to watch out for.
In contrast, autumn 2025 precipitation in Novosibirsk is expected to be slightly wetter than 2024 but within the multi-year norm. Meanwhile, autumn in Russia as a whole is predicted to be warmer than usual.
Interestingly, the Altai region has already experienced leaf fall, according to a biologist, despite the usual time for this event occurring later in the year. The reason for the early leaf fall is not explicitly stated in the text, but it is likely due to a combination of natural and human-induced factors that are stressing local forests. Specifically, degradation of forest shelterbelts under the dry steppe conditions in the Altai Territory has been linked to these complex impacts, which include both climatic variations and anthropogenic influences such as land use changes or forest management practices.
Such stresses can prompt trees to shed leaves earlier as a survival response. Although no direct study from 2025 explicitly details leaf fall timing in Altai, the identified degradation of forests in that region and climate-related changes affecting vegetation dynamics in nearby northern China suggest similar ecological processes might be at play. Additionally, fluctuating trends in vegetation growth and climatic shifts across northern Asia, including earlier seasonal transitions, can cause leaf senescence to occur sooner than usual.
In summary, early leaf fall in Altai is mainly driven by forest degradation exacerbated by dry conditions and anthropogenic factors, combined with broader climate variability influencing autumn phenology in the region. It will be interesting to see how these weather patterns continue to evolve in the coming weeks.

In the context of the unusual autumn weather, climate change and forest degradation in the Altai Territory may have contributed to the early leaf fall observed there. This could be connected with the degradation of forest shelterbelts under dry steppe conditions, alongside anthropogenic influences on land use and forest management practices. Furthermore, increased precipitation in key cities like Krasnoyarsk and Novosibirsk could lead to wetter autumns than average, with Krasnoyarsk potentially experiencing its wettest autumn in the last 5 years.
