Honolulu sounds like a year-round summer, but the rain patterns matter. I packed for beaches in November and got three wet days — the windward side gets 4x the rain of Waikiki. The sweet spot is April-May: 26°C, low rain, fewer tourists. December-March brings the big surf and whale season, plus occasional showers. Pack reef-safe sunscreen (mandatory by law), rash guard for snorkeling, and a light rain shell for windward trips. Summer (June-August) is hotter and more humid but trade winds keep it manageable. Skip spring break crowds in March — Waikiki gets packed.
