Rain season
Shanghai's meiyu season (late June to mid-July) is a period of persistent, grey, humid rain similar to Tokyo's tsuyu. Typhoons in August–September can bring extreme rainfall — a direct hit can deliver 100mm or more in a day. Winters are cold, damp, and occasionally snowy; spring (March–May) is mild with light showers.
