Honolulu started Wednesday on the warm and muggy side, with mostly clear skies, early lows near 73°F and afternoon highs headed for about 84°F. Light land and sea breezes are running the show for now, but a more typical trade-wind pattern is expected to kick back in late Wednesday and ramp up through Thursday and Friday. That shift will mean breezier afternoons and most showers getting shoved back toward windward and mauka slopes. Ocean goers, take note: advisory-level surf is building on many east-facing shores into Thursday.
Afternoon And The Week Ahead
Trade winds are forecast to redevelop late Wednesday and strengthen into Thursday and Friday, which should help knock down the sticky feel and keep most showers focused over windward and mountain areas. Afternoon highs will sit in the low to mid 80s, with overnight lows holding in the low 70s. National Weather Service Honolulu
Surf And Coastal Hazards
A moderate north-northeast swell is already pushing surf on east-facing shores up to advisory levels, and a High Surf Advisory is posted through Thursday for many of those beaches. Expect strong, breaking waves and dangerous rip currents; lifeguards are telling people to stay well back from the waterline and skip swimming at exposed spots for now. Weather.com
Marine And Wind Outlook
Trade winds should strengthen to moderate to locally fresh by Thursday and Friday, with east-northeast winds in the teens and gusts into the 20s by the weekend, so plan for breezy afternoon commutes and gusty ridge tops. Forecasters also point to lingering west-northwest swell energy that may keep surf up at select west-facing breaks through the end of the week, which will leave conditions choppy for small craft.

What To Do Today
Front-load any beach and boating plans earlier in the day and steer clear of exposed beaches while advisories are in effect. Tie down or bring in loose outdoor items before the gusty afternoons kick up. Boaters should be cautious in choppy seas, check in with local ocean safety or harbor officials before heading out, and keep an eye on updated forecasts later today.
