## 🎯 Key Points

- UkrHMC does not use the term "Indian summer" at the official level.
- Warm autumn periods are explained by the regular arrival of anticyclones.
- Several such periods can be observed in September and October per season.
- The current first decade of October 2026 will be under high pressure influence.

Ukrainians look forward to the arrival of "Indian summer" every year, associating this period with the final warm days of autumn. However, professional meteorologists and forecasters from the Ukrainian Hydrometeorological Center approach this issue strictly from a scientific perspective. As Natalia Ptukha, Head of Media Relations at the UkrHMC, explained, specialists of the official agency do not use this term in their professional work, considering it exclusively a folk name.

### Scientific Essence of the Phenomenon and the Role of Anticyclones

From a meteorological standpoint, the so-called "Indian summer" refers to periods of stable anticyclonic weather that regularly alternate with rainy and overcast cyclones. Throughout the year, a natural alternation of atmospheric processes occurs: calm sunny days are replaced by incoming atmospheric fronts. When such an anticyclone settles in during the autumn period and is accompanied by a warmed air mass, citizens experience a feeling of returning summer heat. At the same time, forecasters record only indicators of atmospheric pressure, wind speed, and temperature.

### Why There Can Be Multiple "Indian Summers" Per Season

Many people wonder why there are several warm periods in autumn. According to the UkrHMC representative, this is directly related to the frequency of alternating anticyclonic processes across the country. Such periods can be observed both in September and throughout October or even November. Official science does not establish clear calendar boundaries or rigid meteorological parameters for defining "Indian summer," describing what happens purely as a synoptic process of increased atmospheric pressure.

### Controversial Data

While official meteorology avoids the term "Indian summer," folk beliefs and unofficial forecasts often associate this phenomenon with specific dates or natural markers. For example, in everyday life, it is customary to consider classical "Indian summer" to be the warming that occurs immediately after the first night ground frosts. Meteorologists confirm the coincidence of these factors in the current season, but emphasize that they have no authority to officially approve folk names, continuing to operate with dry data on the high atmospheric pressure field and comfortable temperature values of the first decade of October.

### Current Forecasts and Conclusions

Analyzing the current synoptic situation as of October 2026, UkrHMC specialists note that the entire first decade of the month will be under the influence of a high atmospheric pressure field. This guarantees Ukrainians stable and quite comfortable temperature indicators during daytime hours, despite the already noted night ground frosts. Experts remind that Ukrainians can call these comfortable days by any familiar terms, but for science, it remains a natural alternation of air masses and baric formations.
