CatchWindow fishing intelligence

Southbank Riverwalk, St Johns River, FL Daily Water Report — October 5, 2026

Southbank gets a clear green light for low-wind water time today, with kayaking the standout at 8.1/10 and boating close behind at 7.8/10. The river forecast is flat on the marine side—0.0 m waves and no swell—and the representative east wind is just 2 knots, though that calm headline has an evening asterisk: gusts are forecast to reach 18.9 knots around 7 PM. The best all-around window is early, from dawn through the 6:10 AM high tide, when the air is cooler and winds should be light. A second useful stretch arrives around the 8:18–10:18 AM solunar major period, with the tide ebbing toward the 12:21 PM low. Fishing rates 7/10, supported by the day’s tide, light wind, falling pressure, and solunar timing; it is a solid opportunity, not a promise that the bite will be theatrical. The evening high at 7 PM coincides with the strongest forecast gusts, so it is better suited to a short, attentive outing than a leisurely drift. Diving scores 8.6/10, matching yesterday’s high mark, with warm 27 C water and a flat surface forecast helping the model. Atmospheric visibility is forecast near 12.4 km, but that is not a reading of underwater visibility. The available chlorophyll reading is 3.43 mg/m3, classified high, but it should not be treated as a direct report of water clarity or marine activity. Sailing is the odd one out at 4.8/10: flat water is pleasant, but the day offers too little dependable breeze for much useful sailing, followed by a potentially gustier evening. Rain is possible from 4 AM through 11 PM despite a representative precipitation value of zero, and full cloud cover, 95% humidity, and a falling barometer argue for keeping rain gear and a quick exit plan handy. Compared with the recent CatchWindow run, today improves fishing from yesterday’s 7.5 only slightly less, while kayaking rebounds from 7.6 and boating edges above yesterday’s 7.5. The tradeoff is a lower sailing score than the last several days. Tuesday and Wednesday stay flat-water days but bring higher rain chances and stronger peak winds, especially Wednesday at 15 knots. Thursday looks comparatively quieter and drier. Best bet: Launch near dawn, enjoy the glassy river before the heat and showers build, and be off the water before the 7 PM gusty high-tide turn.
