# First day of autumn in Ukraine: where thunderstorms and squalls, and where heat up to +28 — and why the Dnester hit a historic low

## 🎯 Key Points

- On September 1, 2026, Ukraine will see variable cloud cover, with brief rain and thunderstorms in some oblasts, and daytime temperatures reaching nearly +28 °C in places.
- The wind will be predominantly southwesterly, 7–12 m/s; some outlets point to squalls from an Atlantic front in certain zones.
- September 2026 as a whole is expected to stay within the climatic norm: average monthly temperature around +11…+18 °C, precipitation within usual bounds.
- Near Zaleshchyky (Ternopil Oblast), the Dnester broke a historic antirecord for minimum water discharge that had held since 1895.

On September 1, 2026, Ukraine welcomes the calendar autumn under a markedly uneven atmospheric backdrop. According to data from the Ukrainian Hydrometeorological Center, as reported by RBC-Ukraine, most regions will see variable cloud cover, with precipitation of a local character: brief rain and thunderstorms are expected only in some oblasts. At the same time, the daytime temperature background will remain high — in some areas the air will warm to nearly +28 °C, making the first day of autumn feel closer to summer than to a typical September.

### Variable cloud cover and local precipitation

According to the forecast by UHMC specialists, cloud cover on September 1 will be predominantly variable, and rain will not fall everywhere. Meteorologists emphasize that precipitation will be pinpoint and brief, so even within a single oblast the weather may differ significantly from a neighboring one. That is why the emphasis shifts across publications from different outlets: some articles highlight the hot, rain-free parts of the country, while others focus on the zones where downpours and thunderstorms will pass through.

### Temperature background and wind character

During the day on September 1, the air in a number of regions will warm to nearly +28 °C, which looks unusually warm for the start of autumn. The wind is expected to be predominantly southwesterly, at 7–12 m/s. Some outlets additionally point to the influence of an Atlantic front, which in certain zones can intensify the squally character of the wind and trigger local lightning discharges, so when planning outdoor activities on the first day of autumn it is worth accounting for the risk of sharp fluctuations.

### Climatic context of September 2026

Earlier, meteorologists had already outlined the general climatic profile of the month: according to preliminary data, the average monthly temperature for September 2026 is expected to fall within the climatic norm — roughly between +11 and +18 °C — and precipitation should also stay within its usual bounds. Thus, the hot first day of autumn with readings around +28 °C is more of a local, single-day spike rather than a systematic deviation of the entire month from long-term values.

### Historic low on the Dnester

Against the backdrop of a warm, dry start to autumn, the hydrological signal stands out: on August 27, 2026, near the town of Zaleshchyky in Ternopil Oblast, the Dnester recorded the lowest water discharge in the entire period of observations, and the very next day the figure dropped below the minimum that had held since 1895. This historic low-water antirecord becomes an important indicator of the dryness of the period and heightens attention to the region's water resources amid a hot start to autumn.

### Regional unevenness of the forecast

Comparing the materials from RBC-Ukraine and other outlets shows that the UHMC figures (variable cloud cover, local rain, up to +28 °C, wind 7–12 m/s) are consistent, but the headlines place a different emphasis: on the heat and rain-free zones, or on the cooling from the Atlantic front and the squalls. This is not a contradiction in the data, but a reflection of the fact that the first day of autumn in 2026 will be contrasted across regions: somewhere the summer heat will persist, while elsewhere thunderstorms with strengthened winds will pass through.
