CatchWindow fishing intelligence

Southbank Riverwalk, St Johns River, FL Daily Water Report — October 8, 2026

A strong go for boating, kayaking and diving, with fishing solid rather than spectacular; sailing gets enough breeze to function, but not much to brag about. The St. Johns is forecast flat all day, with zero wave and swell height, and a light NNE wind around 5 knots. That makes this a notably easy-moving water day after the pre-dawn gusts, which could reach 20 knots around 2 AM, have passed. For paddlers and small-boat crews, the best practical window is from shortly after dawn through late morning, before the rain window begins at 8 AM in earnest and while winds remain generally light. The morning high tide arrives at 9:06 AM, then water falls toward the 3:24 PM low. A second, quieter-looking option comes around the 9:30 PM high, though darkness and any lingering rain make it a different proposition entirely. Flat water is not a safety guarantee, particularly around changing tides and in poor weather. Fishing rates 6.6/10, helped by light wind, rising pressure and the 10:45 AM–12:45 PM solunar major period. The late-evening major period, 10:45 PM–12:45 AM, overlaps the nighttime high-tide cycle. Water temperature is a warm 28.4 C, about 2.5 C above average. Chlorophyll is measured at 3.43 mg/m³, but that is not a read on fish activity or water clarity. Cloud cover is forecast at 100%, and the listed 13.9 km atmospheric visibility should not be mistaken for underwater visibility. Diving carries the day’s top score at 8.4/10, ahead of boating at 7.4 and kayaking at 7.3. That is an improvement from yesterday’s 7.6 diving score, though boating and kayaking remain a touch below several calmer recent days. Sailing’s 5.3 reflects the tradeoff: smooth water, but modest wind and a cloudy sky. Rain is possible from 8 AM through 9 PM despite zero representative precipitation, so keep an eye on actual conditions rather than trusting the dry-looking summary. Pressure is rising from a low near 1012 hPa toward 1016 hPa. Friday brings stronger wind and a 70% rain chance; Saturday and Sunday stay rain-prone, while Monday onward looks drier with light winds and continued flat marine forecasts. Best bet: launch after dawn, use the morning high tide, and be off the water before the wet part of the day gets ideas.
