Weather-ready Hawaii

What to check before making plans

Heavy rain and flooding

Surf and marine weather

Check high-surf, small-craft, and rip-current information before beach or boating activity.

Wind and volcanic haze

Trade-wind shifts can affect fire weather and vog. Review air-quality information when needed.
