Nantucket Island, MA Daily Water Report — August 22, 2026

Today's conditions on Nantucket Island are prime for diving, with an impressive suitability score of 8.7 out of 10. The stable barometric pressure and calm wind conditions create an ideal underwater experience. The sea surface temperature is a comfortable 21.7°C, and with visibility at 13.2 km, you'll have a clear view of the underwater world. Boaters and sailors will also find today favorable, with scores of 7.2 and 6.8 respectively. Winds are coming from the north at a moderate 7 knots, with gusts peaking earlier this morning. Waves are manageable, averaging 0.6 meters, and should remain calmest around 10 PM. The lack of rain means you'll stay dry above water, making it a pleasant day for cruising around the island. While fishing scores a moderate 5.8, the solunar major period this evening from 5:51 to 7:51 PM aligns well with the high tide at 8:50 PM, suggesting a decent chance for a catch if you're patient. Surfing and kayaking enthusiasts will find today passable, with scores hovering in the mid-5s. The swell is coming from 61 degrees, but the short period of 4.4 seconds might leave surfers wanting more. Wildlife watchers might not have the best day, with a score of 5.7. The high chlorophyll levels signal good baitfish activity, but wind and tide conditions aren't particularly favorable for observing larger wildlife. Looking ahead, tomorrow promises slightly warmer temperatures and a mild increase in wind speed, with a chance of rain. The rest of the week sees varying conditions, with the windiest day expected on the 25th. For those seeking tranquility on the water, mark your calendars for the 27th, when both wave and swell are forecasted to be at their lowest. If you're diving today, you're in for a treat—just remember to take a moment to appreciate the calm beneath the waves.
