Sand Island, Midway Atoll Daily Water Report — August 31, 2026

Today's conditions at Sand Island are a mixed bag, with the best opportunities for fishing, surfing, and diving. The fishing score sits at a solid 8.1, thanks to favorable solunar periods and decent visibility. Early morning and mid-afternoon are your prime windows, aligning with the solunar major periods. Surfing is also promising with a score of 7, driven by consistent wave heights around 2 meters and an easterly swell. However, expect a bumpy ride with wind gusts reaching up to 28.8 knots at noon, which might add some unwanted chop. Diving conditions remain steady with a score of 7.7. The water temperature is comfortable at 27.5°C, and though the visibility is not explicitly noted, the low chlorophyll levels suggest clear blue waters typical of oligotrophic conditions. Just keep an eye on those gusty winds, which could stir things up a bit. Boating and kayaking are less appealing today, with scores of 3.5 and 2.4 respectively. The stiff ESE winds and wave heights make for a challenging and potentially uncomfortable experience on smaller crafts. If you’re keen on sailing, it’s a decent day with a score of 7.9, but be prepared for some strong gusts and shifting conditions. Compared to recent days, diving and fishing are holding steady, while sailing and surfing have dipped slightly from their higher scores earlier in the week. The wildlife score sits at 5.8, indicating moderate activity, possibly affected by the strong winds. Looking ahead, the winds are expected to ease slightly after today, with the forecast showing a gradual decrease in wave heights and wind speeds. By September 3rd, conditions should be much calmer, offering a more pleasant experience for all activities. The best bet for today? Hit the surf during the morning high tide for the best combination of waves and wind.
