Sand Island, Midway Atoll Daily Water Report — October 8, 2026

Sailing is the day’s clearest yes at Sand Island, but it is a brisk, wave-aware yes rather than a leisurely lap. The 7.3/10 sailing score leads the board, with NNE wind around 20 knots and gusts reaching nearly 30 knots late morning. That is useful pressure for capable crews, though the 2.5–2.9 m sea state and short 5.3-second wind waves will keep the ride busy. Cloud cover is complete, air sits near 24 C, and the falling 1015 hPa pressure adds to the sense that the weather is not here to lounge around. For fishing, the 6/10 rating is respectable but down from 6.4 yesterday and well below the stronger 8/10 reconstructed score on October 3. The most favorable timing is the 10:20 AM–12:20 PM solunar major period, with another major window from 10:20 PM to midnight. Tide is low at 8:44 AM, rises to a modest 0.35 m high at 2:53 PM, then falls toward the 9:07 PM low. The early-morning rain window, from 2 AM to 5 AM, is worth factoring into any pre-dawn plan even though representative precipitation is zero. Diving earns 7.1/10, matching yesterday, supported by a marine SST of 26.4 C and available clarity inputs in the score. Still, that rating is not a safety clearance: surface wind and 2.78 m representative waves can make entries, exits, and surface intervals demanding. Atmospheric visibility near 46 km does not describe underwater visibility. The ocean is only slightly warmer than average, at +0.1 C, while chlorophyll is low at 0.06 mg/m³; that is a water-colour/productivity measure, not a wildlife or fishing forecast. Boating and kayaking remain the compromised options at 4.6 and 4.5/10, respectively. The calmest wave height is still 2.52 m near 4 AM, so “calmest” is relative today. Wildlife scores 4.5/10, with the late-afternoon minor solunar period from 4:50–5:50 PM arriving before dusk at 6:53 PM. Friday looks rougher, with 2.9–3.0 m waves, before winds and seas gradually ease into next week; October 13–14 currently offer the softer marine outlook. Best bet: sail smartly in daylight, then let the sea have the last word.
