Most regions of Ukraine will experience rain and potential thunderstorms on Sunday, July 26, 2026 [1].
These weather patterns are driven by a cyclone moving in from the south, which may cause significant disruptions to travel and outdoor activities across the country [1].
Meteorologist Ihor Kibalchych said Ukraine will be under the influence of this southern cyclone, and that rain will fall in most provinces and could be significant in some areas [1]. According to the Ukrhydrometeorological Center, short-term rains and thunderstorms are expected in eastern regions, Crimea, and the Azov coast [2]. The center said that the Luhansk and Donetsk regions should expect significant rainfall [2].
Temperature forecasts vary across reporting agencies. Kibalchych said overnight lows would be between 13 and 18°C and daytime highs would range from 22 to 27°C [1]. Other reports indicate higher peaks, with some forecasts suggesting daytime temperatures reaching 29°C [2].
Regional disparities remain prominent in the south and east. Reports from pravda.com.ua indicate that temperatures in the southeastern regions could climb between 26 and 31°C [3]. This contrast highlights the varying impact of the cyclone as it moves across the national territory, creating a divide between cooler, rain-heavy northern areas and warmer southern zones [1], [3].
While most of the country will see precipitation, one region is expected to remain largely free of significant rainfall [1]. The combination of high humidity and fluctuating temperatures may lead to unstable weather conditions throughout the day.
“Ukraine will be under the influence of a cyclone from the south”
The arrival of a southern cyclone during late July indicates a shift toward unstable summer weather, where intense localized rainfall and thunderstorms compete with high temperatures in the southeast. This pattern suggests a volatile atmospheric transition that can lead to flash flooding in eastern regions like Luhansk and Donetsk while maintaining summer heat in the south.
