Chatham, MA Daily Water Report — September 3, 2026

Today's waters around Chatham are inviting, especially for divers, with a high suitability score of 7.6/10. The sea surface temperature is a comfortable 23°C, and the relatively calm wave height of 0.54 meters, along with the gentle swell, sets the stage for a rewarding dive. Visibility is decent at 12.9 km, though not underwater-specific, it suggests clear conditions above the surface. For anglers, a score of 6/10 suggests moderate success, with the best times aligning with the solunar major periods from 4:32 to 6:32 AM and 4:32 to 6:32 PM. The pressure is falling slightly, and while this sometimes stirs the fish, the wind from the southeast at 7 knots might require a bit more finesse in casting. Surfers might find today a mixed bag with a 5.8/10. The waves are manageable, peaking at around 0.8 meters, but the short period of 4.5 seconds could make for a choppy ride. It's not the best day we've seen recently, but still worth a paddle out for the dedicated. Sailors might enjoy the 6.5/10 conditions thanks to the steady southeast breeze, though gusts up to 17.9 knots around midday could add some excitement. Boaters and kayakers should be cautious of the wind and ocean current, which is moving at 2.2 m/s towards 275 degrees, pushing westward. Looking ahead, the weather remains stable with temperatures slightly rising over the next few days. Winds are expected to increase on the 6th, which could affect all water activities. For now, if you’re diving, today’s conditions are your oyster.
