If you have planned a lakeside getaway or a week by the Baltic coast for early July, you may be frustrated by the unseasonably chilly and wet weather. But which month is a safe bet in rainy Lithuania? Long-term weather data suggest it’s still July – only later.
While this summer has been marked by frequent rainfall, historical records show that July is, on average, Lithuania’s warmest summer month, followed by August, with June typically the coolest.
Meteorologist Gytis Valaika, of Lithuania’s Hydrometeorological Service, analysed data covering the period from 1961 to 2025 and found that July was the warmest month of the summer in 43 of the 65 years studied.
August ranked as the warmest in 15 summers, while June held that distinction only seven times, most recently in 2019 and 2020.
Breaking the summer into nine 10-day periods, the analysis found that the third 10-day period of July and the first 10-day period of August are, on average, the warmest parts of the season, with mean temperatures of 19.1 degrees Celsius and 18.9 C, respectively.
Those same periods were also the warmest stretch of the summer in 27 of the 65 years analysed, making them the statistically most favourable time for planning a summer vacation.
By contrast, the first and second 10-day periods of June were the coolest part of the summer in 43 of the 65 years, suggesting they are the least suitable choice for people seeking warm weather.
The analysis also compared average temperatures with precipitation totals. It found that the warmest period generally runs from July 25 to August 15, when average daily temperatures exceed 19 C.
When both temperature and rainfall are taken into account, the most favourable holiday period is even narrower, stretching from about July 25–26 to August 8–9, when conditions are, on average, both the warmest and driest.
According to the Hydrometeorological Service, the statistics suggest that the final week of July and the first week of August offer the best chance of warm, dry weather for summer vacations in Lithuania.
