Oʻahu beach forecast
United States · 17 beaches and resorts
Veabird grades 17 beaches and resorts in Oʻahu, United States, every six hours on seaweed, water, waves, weather and crowds. The most are in Waikīkī, Ko Olina and Honolulu. These beaches sit outside the Atlantic sargassum belt, so seaweed is rarely a factor. Across the region, average highs run from about 80°F in January and February to 88°F in August and September, and the sea from about 75°F to 81°F. Rain is most likely in January and December and least likely in June and August.
