Honolulu Harbor, HI Daily Water Report — August 27, 2026

Today's conditions at Honolulu Harbor are a mixed bag, but there's something for everyone. Surfers will be thrilled with a high score of 9.1/10, thanks to the 1.32-meter waves rolling in at a solid 9.8-second period. The swell coming from 184 degrees pairs well with the easterly winds, making for some excellent rides. The calmest wave conditions are expected around 3 PM, so plan your session accordingly. Sailors can also look forward to a great day with an 8.7/10 suitability score. The consistent ENE winds, averaging 9 knots and gusting up to 21 knots, offer exciting conditions for a spirited sail. With minimal cloud cover and no rain in sight, visibility remains excellent at nearly 20 kilometers. Divers will find the water temperature at 27.1°C quite inviting, earning an 8.6/10 score. The low chlorophyll levels indicate clear, oligotrophic waters, perfect for exploring beneath the surface. However, the current running at 0.4 m/s towards 243 degrees might require some extra effort to navigate. Fishing enthusiasts have a decent window to cast their lines, scoring a 7/10. The solunar major periods between 8:57-10:57 AM and 8:57-10:57 PM, coupled with stable barometric pressure at 1015 hPa, suggest good chances for a catch. Boaters and kayakers face a bit more challenge with scores of 6.9/10 and 5.1/10, respectively. The wind waves peaking at 0.72 meters could make for a bumpy ride, and the stronger gusts might require more cautious navigation. Looking ahead, conditions remain favorable for the next few days, though a slight increase in wave height and swell is anticipated. For a memorable outing, hit the surf this afternoon when the waves are just right and the sun is high, promising a spectacular session on the water.
