CatchWindow fishing intelligence

Southbank Riverwalk, St Johns River, FL Daily Water Report — October 4, 2026

Southbank gets a clear go for low-wind water time today, with kayaking, boating, fishing and diving all scoring well—but bring patience rather than sails. The river is forecast flat, with 0.0 m waves and a light northwest breeze generally under 6 knots. That makes for easy handling on the water, though it also leaves sailing at a merely workable 5.6/10: plenty of calm, not much push. The strongest all-around window is early morning into mid-morning. Dawn arrives at 6:58 AM, sunrise is 7:22 AM, and the 7:19–9:19 AM solunar major period overlaps the ebb from the 4:55 AM high toward the 11:09 AM low. Fishing rates 7.5/10 under the combined tide, wind, pressure and available clarity inputs, while wildlife rates 7.2/10. The late-day high tide at 5:53 PM is followed closely by the 7:19–9:19 PM major period, offering a second worthwhile outing before dusk at 7:35 PM. Kayaking earns 7.6/10 and boating 7.5/10, supported by the near-glassy forecast and no expected precipitation. The tradeoff is the weather: cloud cover is forecast at 97%, humidity 94%, and temperatures rise from about 23.4 C to 30.1 C. Atmospheric visibility is forecast around 12.3 km, but that is not a read on underwater visibility. Diving leads the board at 8.6/10, helped by calm water and a 27.2 C water temperature; it is 1.1 C above average. Conditions are not a safety guarantee, and the falling 1016 hPa pressure deserves a glance before committing to a long session. Compared with the reconstructed recent CatchWindow history, fishing improves sharply from 6.6/10 yesterday, while diving rises from 7.6/10. Boating eases from yesterday’s 8.6/10, and kayaking is slightly below yesterday’s 8.2/10, though still comfortably favorable. The quieter pattern does not last untouched: Monday through Wednesday bring higher wind peaks and substantial rain chances, while the marine forecast remains flat through the week. Best bet: launch around first light, work the morning major period, and enjoy the rare luxury of a river that has misplaced its wrinkles.
