The weather in Ukraine over the next day and the weekend will be contrasting: in some regions, forecasters promise significant rain and localized thunderstorms, while in others there will be variable cloudiness with no precipitation and autumn-like comfort. The Ukrainian Hydrometeorological Center (UkrHydmet) has issued a warning about hazardous meteorological phenomena, and the wind in most regions will be predominantly north-easterly at 5–10 m/s.

UkrHydmet warning: where dangerous rain is expected

According to the official forecast of the Ukrainian Hydrometeorological Center, moderate and, in places, heavy rain is expected over part of the country in the coming day, with thunderstorms possible in some areas. It is these regions that fall under the warning about hazardous meteorological phenomena for Saturday, September 12. Forecasters remind that such weather conditions may lead to deteriorating road conditions and localized flooding, so drivers and pedestrians are advised to be cautious and, where possible, avoid staying near trees and weakly secured structures during a thunderstorm.

Weather in Kyiv and the Kyiv region

Over Kyiv and the Kyiv region on September 12, cloudy weather with clearings is expected. The wind will be north-easterly at 5–10 m/s. Thermometer readings in the capital will show a gradual rise during the day, while nighttime values will remain around +14 °C. From September 15, according to UkrHydmet, a likely drop in nighttime temperature by several degrees is expected.

Temperature background: daytime rise and nighttime stability

Across Ukraine as a whole, there is a trend toward a further rise in daytime temperature, while nighttime values over the next few days will remain roughly at the same level — around +14 °C. This contrast between day and night is typical of the transitional autumn period and is explained by the alternation of air masses. UkrHydmet specialists emphasize that exact temperature values depend on local conditions and the measurement method, so small discrepancies between the forecast and household thermometer readings are acceptable.

Forecast for September 13–14

During September 13–14, moderate rain and localized thunderstorms are expected in certain regions. On Sunday, September 13, significant precipitation is likely in some areas during the day. Over the rest of Ukraine, the weather will be predominantly dry with variable cloudiness. The wind will remain predominantly north-easterly at 5–10 m/s. Thus, the weekend will be contrasting: residents of several regions should prepare for rainy weather, while the rest of the territory is expected to see a calmer and drier situation.

Contradictory data

The core of the forecast — the presence of heavy rain and thunderstorms in certain regions on September 12–14 — is confirmed by all verified sources and official UkrHydmet data. However, there is a slight difference in how the temperature dynamics are emphasized: a number of publications focus on an “unexpected cooling,” whereas the official UkrHydmet chart records a trend toward a gradual rise in daytime temperature with stable nighttime values around +14 °C and a likely drop in the nighttime reading only from September 15. The difference is explained by the fact that “cooling” in editorial headlines more often refers to the subjective sensation caused by humidity and wind, while the instrumental forecast records a moderate daytime rise. No significant discrepancies in dates or figures between sources were found.
