Southbank Riverwalk, St Johns River, FL Daily Water Report — September 1, 2026

Today on the Southbank Riverwalk, it's a prime day for boating and kayaking, with scores of 9.5 and 9.2 out of 10, respectively. The St. Johns River is serving up glassy conditions with absolutely no wave action, making it perfect for a smooth paddle or a leisurely cruise. The wind is a gentle northerly breeze averaging 3 knots, peaking at 15.7 knots around noon, which might add a touch of excitement for sailors but isn’t too disruptive for other activities. Fishing enthusiasts will find decent conditions with a 7/10 score. Although the chlorophyll levels are high, promising good baitfish activity, the best catch might come during the solunar windows of 3:30-5:30 AM and 3:30-5:30 PM. The waning gibbous moon might not be your best ally, but the tide swings could work in your favor. Surfing isn’t on the cards today with a score of 4.5/10, as the wave and swell heights are non-existent. Divers, however, can enjoy an 8.6/10 experience thanks to the calm conditions and a water temperature of 27.1°C, although it's slightly cooler than usual for this time of year. Looking ahead, the weather will get warmer with temperatures peaking at 37.4°C by September 5th. Expect some windier conditions tomorrow, with gusts reaching 11.1 knots, and keep an eye on rising chances of rain later in the week, especially on September 4th, with a 57% chance of precipitation. For today, if you’re seeking tranquility on the water, grab a kayak or hop on a boat and enjoy the serene glassiness of the St. Johns River.
