Rain season
Honolulu has a gentle, year-round tropical climate with a wet season (November–March) when Pacific fronts bring the most rain, and a drier summer. Annual totals average 560mm in the city, though the Ko'olau Mountains directly behind Honolulu receive vastly more. Trade winds keep temperatures comfortable year-round. Severe weather is rare; tsunami risk from Pacific earthquakes is the greater natural hazard.
