SeasonMap

Storm season, month by month around the world

Tornadoes, derechos, hail — the afternoons to watch the sky.

This is a warning page, not a recommendation. Storm season covers 30 destinations on SeasonMap; the months below are the ones in which the risk window is open — most weeks in them pass quietly, and the score beside each place is still the ordinary climate score, hazard and all.
