Honolulu is waking up sticky and gray this morning, with muggy air, light rain and temperatures hovering near 74°F. Skies should turn partly sunny at times, and the afternoon high is expected to reach about 81°F. Offshore, though, the real action is in the water, where large northwest swells are driving dangerous surf into north and west-facing shores while higher-than-predicted tides threaten minor coastal flooding overnight into early next week.
Surf, Tides and Coastal Flooding
Large to extra-large northwest swells are forecast to keep surf above advisory and warning levels on exposed north and west shores through Saturday evening (January 31). The National Weather Service has issued a Coastal Flood Statement through Monday, February 2, 2026, noting that isolated minor flooding is possible at and around the daily peak tides, mainly between midnight and sunrise.
Residents and visitors should be ready for beach erosion, overwash at boat ramps and occasional saltwater on low-lying roads in the most vulnerable spots, especially along the North Shore and Waianae Coast. For specifics on timing and affected areas, check the National Weather Service.
Afternoon Winds And Weekend Outlook
Scattered showers remain in the cards today, with roughly a 40–50% chance of rain at times and localized totals of a quarter to a half-inch in the stronger cells. Drivers should be ready for slick roads during the afternoon commute.
Winds will generally run from the northeast to east through the weekend, then strengthen ahead of the next front. By Monday, southwest breezes are expected to peak, with gusts becoming notable in more exposed areas. Boat operators and weekend sailors should plan for rough seas and follow any posted Small Craft Advisories and harbor guidance.
What To Watch And How To Stay Safe
Avoid walking or driving near exposed shorelines during high tide and stay off sea cliffs and coastal benches while high surf alerts are in effect. If you normally park near the shore, move vehicles and valuables to higher ground. Secure small craft, follow posted beach closures and, if your vehicle is forced through salt water, rinse it with fresh water as soon as possible…
