Sweden Weather & Climate Guide 2026

Sweden's climate in numbers — the months that flatter it, the ones to avoid, and what to pack.

Discover Sweden, a Scandinavian gem blending stunning natural beauty with modern design and rich Viking heritage. From the cosmopolitan streets of Stockholm to the Northern Lights in Lapland, Sweden offers diverse experiences year-round.

Sweden has a temperate climate moderated by the Gulf Stream, with significant variation from south to north. Stockholm and southern Sweden experience warm summers (June-August reaching 20-25°C) and cold winters with snow. Lapland in the far north has an Arctic climate with long dark winters and a brief but spectacular summer featuring the midnight sun. Rainfall is moderate year-round; the west coast receives more precipitation than the east.
