Lithuania braces for a cool spring and potentially hot summer

Meteorologists note that Lithuania’s spring has been unusually cold and windy, with delayed plant development and higher than normal groundwater levels. Local observations compare the current conditions to the harsh 1978 summer, recalling strong winds, dry spells and heavy rains that followed. European (ECMWF) and U.S. forecast models anticipate a warmer-than‑average summer across the region, with increased heat‑wave risk, longer dry periods and occasional strong thunderstorms.

A detailed sinoptic forecast for early June predicts a gradual shift from mild, dry days to warmer temperatures as southerly air masses arrive. The first day of the calendar summer (June 1) should be clear and dry, followed by steady warming through the week, with the southern and southeastern winds bringing higher humidity and the likelihood of thunderstorms by mid‑week. Temperatures are expected to rise from the high teens (°C) at night to the mid‑20s during the day, reaching the upper 20s in the later part of the week.

These outlooks suggest that while the spring may stay cool, the upcoming summer could bring significant heat and sporadic heavy rain, influencing agriculture, outdoor activities and public health across Lithuania.
