Honolulu in March — Full Picture
March is Hawaii's spring drying-out month — rain drops to 7 rainy days, 60mm rainfall, with afternoon trade-wind clouds clearing into evening. US spring break peaks mid-March (mainland college students from Pacific Northwest universities) — hotels surge for spring break weeks.
Honolulu Festival (the second weekend of March) is a free 3-day Japanese-Hawaiian cultural celebration — parades, traditional dance performances, Friday-night Honolulu Festival fireworks at Waikiki Beach (free). Significant Japanese tourist inbound for the festival weekend.
Waikiki sunset and Diamond Head sunrise are both at peak conditions. Whale season tapering — sightings still reliable through March (whales head back to Alaska for summer feeding). North Shore winter waves still firing through mid-March.
The smart March move: target the first or last week (avoiding mid-March spring break) for pre-Korean-Golden-Week pricing. Pearl Harbor reservations still need 60-day pre-booking.
