Mayport (Bar Pilots Dock), FL Daily Water Report — October 4, 2026

Mayport gets a strong go for small-craft boating, paddling, and diving today, with one important asterisk: the water is easygoing, but the sky is not especially inviting. Light west winds around 3 knots, generally 0.4–0.5 m seas, and only a trace of wind chop make this one of the smoother days to get afloat. Boating rates 8.7/10, kayaking 8.9, and diving 8.6—not safety guarantees, but a fair reflection of the low wind and modest sea state. The best all-around daylight window is late morning into early afternoon. Seas reach their daily minimum near 11 AM at about 0.42 m, while the tide has turned from the 9:17 AM low and is building toward the 4:07 PM high. That rising-water stretch also overlaps the 1:48–2:48 PM solunar minor period. For anglers, the sharper opportunity is dawn through mid-morning: the 7:18–9:18 AM major period lands around the morning low, with another major period from 7:18–9:18 PM after sunset. Fishing scores 7.5/10, improved from the reconstructed 6.7 on October 3, though pressure is falling and the day remains heavily clouded. The tradeoff is heat and humidity rather than rough water. Air temperatures reach 29.7 C, with a representative feels-like temperature near 30.3 C and 95% humidity. Cloud cover is forecast at 100%, and rain is possible through 9 PM despite zero representative precipitation. Atmospheric visibility is forecast near 12.6 km; that is not a measure of underwater visibility. Marine water is warm at 28 C, about 0.9 C above average, while the available ocean current runs about 0.11 m/s toward 63 degrees. Sailing is merely middling at 5.2/10: the breeze is too light to do much work, even if the water is cooperative. Wildlife scores 7.8/10, with the afternoon low-light/low-tide-adjacent timing worth watching around the 10:15 PM low, though that is after dusk. Conditions turn less forgiving after today: Monday stays relatively small, but rain chances rise, then winds and seas build Tuesday through Thursday, with 0.8–1.5 m waves Wednesday and 1.0–1.4 m Thursday. Best bet: launch late morning, enjoy the glassier 0.42 m seas, and be back in before the humid sky decides it has something to say.
