Overview
May is a transition month in Rovaniemi: winter snow melts, rivers thaw, and daylight stretches toward the midnight sun. It's green and fresh, but not aurora season.
No aurora in May
By May the nights are too bright for the Northern Lights — the aurora season runs September to April. Come in winter for the lights.
What to do
Early spring hiking, river activities as the ice breaks, visiting the year-round Santa Claus Village, and enjoying long, bright evenings.
Weather
Mild and variable (around +5 to +15°C), with snow lingering early in the month at higher spots.
