Hawaiʻi weather alerts
Statewide National Weather Service alerts. Check the named areas: an alert may affect only part of an island.

This page is a planning aid, not an emergency notification service. Follow county instructions, closures and lifeguards. A clear forecast or empty alert list does not establish that a beach is safe.
Honolulu forecast
Each forecast is for the named town, not the whole island. Mountain, windward and coastal conditions can differ sharply.

Radar & live maps
Check where rain is moving with official radar, then compare wind and waves on the surf map. Radar shows precipitation; it does not establish safe ocean or trail conditions.
What is the surf doing?
Compare official shore-facing forecasts, check the swell outlook, and open Surfline spot reports, cameras and regional wave maps.
