Honolulu weather,
live right now

April-May and September-October. Warm (24-28°C), drier than winter, less crowded. December-March is whale-watching season (humpbacks visible from shore) but rainier and full of mainland holidaymakers. June-August is hot and busy. November is the start of winter rain. The trade winds blow year-round at 15-25 km/h, keeping it comfortable even in summer. Sea temperature stays 24-27°C — always swimmable.

Tropical casual. Swimwear (you'll wear it daily), board shorts, light t-shirts, sandals or flip-flops. Rashguard for snorkeling (sun protection over sunscreen, also reef-safe). Light dress or aloha shirt for evenings (Hawaii's 'dress code' is famously relaxed). Reef-safe sunscreen is legally required — most regular sunscreens are banned. UV is intense (10-12) year-round. Light rain jacket for sudden tropical showers. Water shoes for rocky beaches.

June 1 to November 30. Direct hits on Honolulu are rare (most storms curve north), but tropical storms passing nearby bring 2-3 days of heavy rain, big surf, flight delays. Major hurricanes hit roughly every 10-20 years (Iniki 1992, Lane 2018 came close). Check NOAA's Central Pacific Hurricane Center if visiting in season. Most tourist activity continues unaffected. Cruise ships sometimes reroute. The big surf from distant storms makes North Shore unsafe for swimming.

Trade winds blow from the northeast at 15-25 km/h almost year-round — Hawaii's natural air conditioning. They keep temperatures comfortable (24-28°C with breeze feels like 22°C with no wind), bring brief mountain rain showers, and create the ideal climate for tropical living. When trades fail (called 'Kona weather' — about 10% of days), Honolulu becomes humid and sticky, sometimes with volcanic smog ('vog') from the Big Island. Trade-wind days are 'normal' Hawaii; Kona days are when locals complain about weather.
