Sand Island, Midway Atoll Daily Water Report — August 23, 2026

Today at Sand Island, Midway Atoll, the water conditions are a mixed bag, with some activities more favorable than others. Surfing enthusiasts will find the 2.96-meter waves and a swell from 59 degrees quite appealing, scoring a solid 7.3/10. Divers can also rejoice with a high suitability score of 7.6/10, thanks to the relatively stable wind conditions and decent water clarity. Fishing presents a decent opportunity today, with a score of 6.8/10, particularly around the solunar major periods from 06:08 to 08:08 and again from 18:08 to 20:08. The waxing gibbous moon further enhances these windows. However, boaters and kayakers should exercise caution. The wind gusting up to 21.8 knots and significant wave height make for a challenging day on the water, reflected in the low scores of 3.4/10 for boating and 2.4/10 for kayaking. The air temperature will be comfortable, hovering around 26.2°C, with a slight humidity-driven "feels like" of 27.6°C. Visibility is excellent at over 40 kilometers, so enjoy the expansive views if you're sticking to the shore. The sea surface temperature is 27.3°C, slightly cooler than usual, which might be a refreshing dip for those brave enough to tackle the waves. Looking ahead, the wind is expected to ease slightly over the coming days, with wave heights gradually decreasing, making conditions more favorable for boating and kayaking later in the week. By August 27th, waves are forecasted to drop to a more manageable 1.5 to 1.6 meters. In summary, today is a surfer's and diver's delight, while other activities might require some patience or a weather window later in the week. For the best bet today, grab your board and hit the surf early to catch the morning swell.
