CatchWindow fishing intelligence

St. Petersburg, FL Daily Water Report — August 28, 2026

Boating and fishing are the clear winners today, with the afternoon high tide turning the flats into prime territory. If you have a boat or kayak, the window from late morning through mid-afternoon is your best bet, with scores hitting 8.5 and 8.2 respectively. Winds out of the southeast are light and steady, running 6 knots with gusts just touching 10, so the Gulf and bay will be slick—wave heights barely reach 0.2 meters. The full moon overhead means solunar activity peaks midday, aligning with that 12:33–14:33 major period, so fish should be feeding aggressively. Be aware that visibility is 18.7 kilometers, so atmospheric haze isn't the issue, but this morning's low tide at 08:38 drops water levels more than you might expect given the modest 0.58-meter high tide before dawn. That early-morning low is the tricky part—wading anglers or kayakers on shallow grass flats might find themselves scraping bottom or trudging through mud until the incoming tide pushes back over the bars by 10 or 11 a.m. Surfing remains a non-starter at 4.5 out of 10; those 3-second wind waves and swell from the southwest offer no shape or push worth paddling out for. Looking at recent history, today’s conditions are a modest improvement over yesterday, when slightly lighter winds and lower pressure pushed boating to 7.4 and fishing to 7.3. The stable barometric pressure at 1018 hPa and the 31.5-degree sea surface temperature mean the water is warm and settled, but divers will have to wait—no score is available today, likely due to limited visibility data. Wildlife watchers get a solid 7.4, bolstered by the low-tide stretch early and those solunar periods; shorebirds and dolphins should be active along the passes and sandbars. Tomorrow brings a slight uptick in wind to 10 knots and a 52 percent chance of rain, but seas stay small through the weekend. By Sunday, a stronger system moves in with gusts near 22 knots and an 83 percent rain chance, so today’s calm is your best shot for clean runs and tight lines. The early kayak session in the northwest corner of the bay, where the flood tide first spills over the grass, is the kind of peaceful, fishy start that makes August worth sweating through.
