In the north and east coastal region, which includes Taipei, there isn't really a dry season. Winter is cool, occasionally chilly, and is characterised by heavy cloud cover and frequent drizzle. Statistically, more rain falls during summer, but tends to come in short, torrential thunder showers, mostly during the afternoon. Summers are sticky and very hot.
