Vilnius has a [[humid continental climate]] ([[Köppen climate classification]] ''Dfb''),<ref>{{cite journal |vauthors=Kottek M, Grieser J, Beck C, Rudolf B, Rubel F |year=2006 |title=World Map of the Köppen-Geiger climate classification updated |journal=Meteorol.

Temperatures in the city have increased significantly during the last 30 years, a change which the [[Lithuanian Hydrometeorological Service]] attributes to human-induced [[global warming]].<ref name=meteo>{{cite web |url=http://www.meteo.lt/english/climate_change.php |title=Climate change in Lithuania |publisher=Lithuanian Hydrometeorological Service under the [[Ministry of Environment (Lithuania)|Ministry of Environment]] |access-date=18 August 2014 |url-status=dead |archive-url=https://web.archive.org/web/20140819090731/http://www.meteo.lt/english/climate_change.php |archive-date=19 August 2014}}</ref>

Summer days are warm to hot, especially in July and August, with daytime temperatures above {{cvt|30|°C|0}} during periodic heat waves. Outdoor bars, restaurants and cafés are frequented during the day.

Winters can be very cold, although temperatures above {{convert|0|°C|°F}}; still occasionally occur. Temperatures below {{cvt|-25|C|F}} are recorded every other year. Vilnius's rivers freeze in particularly cold winters, and the lakes surrounding the city are almost always frozen from December to March, and even April, in the most extreme years. The Lithuanian Hydrometeorological Service, headquartered in Vilnius, monitors the country's climate.<ref>{{cite web |title=Lithuanian Hydrometeorological Service |url=http://www.meteo.lt/en/ |website=meteo.lt |access-date=7 August 2020}}</ref>
