Vilnius, the capital of Lithuania, sits in the southeast of the country at the confluence of two rivers, on rolling hills well inland from the Baltic Sea at approximately 54.69°N, 25.28°E. Its inland, northerly position gives it a humid continental climate (Köppen Dfb) — with warm, changeable summers and cold, snowy winters — more continental than the Lithuanian coast.

Summer, from June to August, is mild to warm, with July the warmest month — average highs around 23–24°C and cool nights — though warm spells can occasionally exceed 30°C. It is the wettest season, with showers and thunderstorms frequent, but also the brightest, with long northern daylight hours and green, pleasant conditions between passing Atlantic fronts.

Winter, from December to February, is cold and snowy, with January the coldest month — average highs around -2°C and lows near -8°C, and cold snaps driven by continental or Arctic air that can plunge below -20°C. Snow covers the ground for much of the season, and the days are short, grey and often overcast.

Vilnius receives around 650–700 mm of precipitation a year, with a clear summer maximum from thunderstorms and a fairly even spread the rest of the year; a good share of the cold-season total falls as snow, which accumulates and lies through the long winter. Live rainfall, humidity, and pressure readings for the city are shown in the panels above.

Vilnius's inland position, far from the moderating Baltic, gives it colder, snowier winters and warmer summers than coastal Lithuania — a genuinely continental climate. The great swing in daylight, from long luminous summer evenings to brief grey winter afternoons, shapes the northern year as much as the temperature does.
