How we pick the best months

  • Best: an average temperature of 15–28°C and low rainfall for Vilnius: under 150 mm, and no more than 69 mm, a quarter above Vilnius's median month (never set below 60 mm).
  • If no month qualifies, we show the three driest months that average 10–30°C instead.
  • Wet: 150 mm of rain or more. Rainy: more than 69 mm. Hot: 29°C or more on average. Cool: under 15°C. Cold: under 5°C.

Averages cover day and night, so afternoons are warmer than the figure shown. Weather is only one reason to pick a month: school holidays, festivals and prices matter too.

Where these numbers come from

Monthly averages for January 2001 – December 2020 from the NASA POWER project, for the area around Vilnius International (VNO) at 54.63, 25.29. The model covers a grid about 50 km across, so a coastal or hilly spot can run a degree or two different. Retrieved 12 September 2026.

The data was obtained from the National Aeronautics and Space Administration (NASA) Langley Research Center (LaRC) Prediction of Worldwide Energy Resource (POWER) Project funded through the NASA Earth Science/Applied Science Program.
