Forecast

Sumy has a humid continental climate. Winters are cold, while summers are warm. Weather can change quickly because Sumy lies far from oceans on the open East European Plain. Air from the Atlantic can bring milder, wetter weather, while air from the east can bring very cold or very hot conditions.

In winter, strong high pressure often forms over northern Asia. This brings clear, dry, and freezing weather. Atlantic low pressure systems can move in and bring clouds, snow, wind, and short thaws. Snow cover is common, but its depth and length can change from year to year.

Spring brings rising temperatures and changing air pressure. Low pressure systems often cause rain and windy days. Summers are usually warm, with many sunny periods. High pressure can create hot, dry weather, while low pressure and passing fronts can bring heavy rain and thunderstorms.

Autumn becomes cooler and wetter. Early autumn may still have warm days, but cold air becomes more common later. Sumy’s inland location causes larger temperature changes than places near the sea. The nearby Psel River and gently rolling land have a small local effect, but they do not greatly change the city’s overall climate.
