Finland experiences a cold, temperate climate dominated by subarctic and continental conditions, with long, dark winters and short, mild summers. The country spans 338,000 km², featuring diverse topography from coastal areas to northern Lapland, but climate remains relatively homogeneous under Köppen classification primarily Dfc (subarctic) and Dfb (cold, humid continental). Average annual temperatures range from 0°C in the north to 5°C in the south, with heavy snowfall in winter and moderate rainfall year-round. Residents and expats should prepare for extreme winter cold reaching -30°C, limited daylight hours (polar night in the far north), and prepare for seasonal affective challenges, while enjoying vibrant summers with nearly 24-hour daylight and outdoor activities like hiking and sauna culture.
