Zagreb, the capital of Croatia, sits in the north of the country on the Sava River, on a plain at the southern foot of the Medvednica mountain at approximately 45.81°N, 15.98°E. Its inland, continental position — cut off from the Adriatic by mountains — gives it a humid continental climate (Köppen Cfb/Dfb) with warm summers and cold winters, quite unlike the mild Croatian coast.
Summer, from June to August, is warm and sometimes hot, with July and August the warmest months — average highs around 27–28°C — and heatwaves that can exceed 35°C. It is among the wetter seasons, with frequent, sometimes heavy afternoon thunderstorms building over the nearby Medvednica hills, and the nights cool pleasantly compared with the humid Adriatic coast.
Winter, from December to February, is cold and often grey, with January the coldest month — average highs around 4°C and lows near -2 to -3°C, with frost frequent and cold snaps that can drop well below -10°C. Snow falls regularly and can lie for days or weeks, and the plain readily traps fog and low cloud during still, high-pressure spells.
Zagreb receives around 850–900 mm of precipitation a year, spread through every month with a late-spring and autumn maximum and no dry season; a good share of the winter total falls as snow, and thunderstorms account for much of the summer rain. Live rainfall, humidity, and pressure readings for the city are shown in the panels above.
Zagreb's continental climate could hardly differ more from the mild, sunny Mediterranean coast of Croatia just a couple of hours' drive south — the Dinaric mountains between them block the sea's moderating influence, giving the capital cold, snowy winters and hot, thundery summers. Winter fog trapped on the Sava plain is a persistent feature of the cold season.
