Ukraine expects mostly warm and calm weather on Sunday, July 12, 2026, with potential short-term rains in northern regions [1, 2].

These forecasts are critical for regional planning as different provinces face contrasting weather patterns, ranging from summer heat to persistent rain cycles.

According to reports, maximum temperatures could reach 28°C [1]. The warmest conditions are expected in the east and south of the country [1]. However, meteorological data for the Rivne region suggests a cooler trend, with temperatures reaching only 17°C [4].

Forecasters from TSN and the Ukrainian Hydrometeorological Center, including meteorologist Ihor K, said the outlook [2]. While some reports indicate a calm day without dangerous phenomena in the Odesa region [3], other forecasts suggest a more volatile pattern. Some data indicates a noticeable drop in air temperature, particularly at night, with rains, thunderstorms, and squalls possible across various areas [2].

In the Rivne region, reports vary on the frequency of precipitation. Some sources said that a rainy cyclone continues to dominate, requiring umbrellas daily [4]. Other forecasts describe the activity as limited to short-term rains and thunderstorms in specific locations [5].

These current fluctuations occur against a backdrop of long-term climatic shifts. One report said that by the end of the 21st century, the average duration of summer is projected to increase by 42 days [6].

“maximum temperatures could reach 28°C”

The contradictions between regional forecasts—specifically regarding the Odesa and Rivne areas—highlight the volatility of current summer weather patterns in Ukraine. The disparity between a 'calm' forecast and one predicting 'squalls' suggests a high level of atmospheric instability, while the long-term projection of extended summers indicates a broader shift toward a warmer climate for the region.
