Honolulu is serving up the full trade-wind package Thursday afternoon: mostly cloudy skies, about 76°F at Daniel K. Inouye International Airport, and east-northeast trades already nudging gusts into the 20s. A High Surf Advisory is in effect for south-facing shores through 6 p.m. HST, so exposed south beaches, from Waikiki to the rest of Oʻahu's south shore, are dealing with strong shorebreak and a higher rip-current risk. Isolated trade-wind showers are favoring windward and mauka neighborhoods while leeward spots hang on to more sunshine and that punchy afternoon breeze.
Surf And Beach Safety
South-facing shores are seeing surf in the 7 to 10 foot range this afternoon, enough for occasional wave runup across normally dry sections of beach and shoreline. According to the National Weather Service, the High Surf Advisory runs through 6 p.m. HST and warns that "beachgoers, swimmers, and surfers should heed all advice given by ocean safety officials." Lifeguards are urging people to stay well back from the waterline and skip standing on rocks or sea cliffs that get hit by set waves.
Afternoon Winds Pick Up
Breezy east-northeast trades will keep conditions choppy into the weekend, with daytime highs holding in the low to mid 80s on leeward shores. Expect sustained winds in the mid teens with gusts pushing into the upper 20s along exposed shorelines and ridges, a combo that can make harbor entries tricky for small craft and whip up sand along open stretches of beach.
Boaters And What’s Next
A Small Craft Advisory is also posted for windier channels and waters around Maui County and the Big Island through Saturday, so mariners should favor more sheltered launches and secure moorings before heading out. Trades may ease a bit early next week, but forecasters are watching for another long-period south-southwest swell late Sunday that could bump south-shore surf back up.

Practical Tips
Obey posted lifeguard flags, skip entering the water at unguarded or especially exposed spots, and secure loose beach gear when gusts ramp up. When in doubt, "don't go out" and check local lifeguard and harbor advisories before locking in evening or weekend plans.
