Climate and monthly weather forecast
Sweden

Sweden, positioned in Northern Europe, reaches from the Baltic Sea in the southeast up to the Arctic Circle in the north. Its geography ranges from coastal plains to highlands and mountainous areas, all contributing to its distinct weather patterns that significantly differ throughout the year. The Köppen climate classification indicates that the majority of Sweden experiences a temperate climate. This indicates varying weather conditions that cycle with the changing seasons.

The south coastal areas, classified as humid continental or oceanic using the -3°C (26.6°F) isotherm, benefit from milder winters and relatively cooler summers in contrast to other regions of the country. Conversely, central Sweden falls under a humid continental climate, leading to warm summers and cold winters. The further north one travels, a subarctic climate is encountered, where long, icy winters and brief, cool to mild summers are the norm. These varying climatic conditions bring a unique diversity to the nation's weather, making Sweden a land of climatic contrasts.
