Breezy Honolulu Braces As Big South Swell Lines Up For Weekend

Honolulu starts Thursday, June 11, in classic trade-wind mode: warm, breezy and a bit showery, especially for windward spots. Expect a high near 85°F with scattered, mostly windward showers favoring the morning hours. East-northeast trades will gust into the low 20s, with overnight lows holding in the mid 70s. Most neighborhoods get a mix of sunshine and quick, light showers, so a thin rain layer is smart if you are heading into windward or mauka areas.

Afternoon Outlook

Shower chances are highest before noon, then skies turn partly sunny this afternoon with temperatures again topping out near 85°F. East-northeast winds should run about 12 to 16 mph, with gusts up to 22 mph, and new rainfall totals are expected to stay under a tenth of an inch. These details on timing, wind and rainfall come from the National Weather Service, according to NWS Honolulu.

Surf And Coastal Risk

The real storyline builds later this week. A long-period south-southwest swell generated by a storm near New Zealand is due to fill in late this week and peak Sunday into Monday (June 14–15). Forecast guidance indicates south-facing shores could push toward warning-level surf, with significant wave runup and the potential for minor coastal flooding during the first half of next week. The Samoa buoy is already picking up this swell, a sign that boosts confidence in both timing and size, according to the NWS Area Forecast Discussion.

Boating, Beach Safety And Commute

Once the swell is up, steer clear of exposed shorelines, rocky points and channel entrances, where larger sets and strong surges can catch people off guard. Lifeguards may close certain beaches if the south shore surf climbs past warning thresholds. Small boats and kayakers should think about delaying trips and securing loose gear ahead of the combination of elevated swell and breezy trades. Harbor surges are possible during peak tides early next week, so if you live near the coast, move vehicles and valuables out of low-lying areas. Check the latest local forecasts and surf bulletins before heading out, according to NWS Honolulu.

Bottom Line

Plan on breezy trades, highs near 85°F and hit-or-miss showers through the weekend, with the south swell arriving Sunday and Monday (June 14–15) as the biggest change on the horizon. Keep an eye on updates from lifeguards and the National Weather Service as the swell builds and tidal cycles help amplify wave runup, according to the NWS Area Forecast Discussion.
