Honolulu began the day mostly clear with temperatures in the low 70s and is expected to reach a high near 81°F under mostly sunny skies. East-northeast trade winds will pick up in the afternoon, especially along exposed shorelines, prompting a Small Craft Advisory for coastal waters through early Sunday, while surf on east-facing shores is forecast to increase over the weekend.
Afternoon Winds Pick Up
East to east-northeast winds are forecast at 14–17 mph today with gusts up to about 24 mph, then trending stronger as the weekend rolls in. According to the National Weather Service Honolulu, gusts could reach 30–35 mph in exposed ridges and shorelines by Sunday night, turning those tradewinds into something a bit more serious than a gentle breeze.
Marine And Surf Outlook
The marine forecast calls for fresh to strong east winds and building seas, with many zones seeing rough 7–10 foot seas and east winds around 20–25 knots. The NWS coastal waters forecast notes the Small Craft Advisory remains in place through 6 AM HST Sunday and that east-facing surf may reach advisory levels this weekend. Boat operators should be ready for choppy conditions and patches of reduced visibility in passing showers.
Plan Ahead
If you are headed to the water, secure small craft or delay nonessential trips, and stay well back from breaking waves and rocky shorelines. Harbor advisories and lifeguard closures may be posted, so check county harbor or lifeguard channels before launching. We will update readers if any watches or warnings change.
