CatchWindow fishing intelligence

St. Petersburg, FL Daily Water Report — August 27, 2026

Today shapes up as a decent all-around day on Tampa Bay, with the best windows coming early and late for anyone wanting to avoid the afternoon’s brief rain chance. Boating leads the pack with a 7.4 suitability score, and fishing isn’t far behind at 7.3, making this a good call for anglers who can work around the solunar minor period from 6:18 to 7:18 a.m. The representative wind sits at just 4 knots from the south-southwest, with gusts staying under 7 knots through most of the morning. That’s a noticeable drop from yesterday’s 6.5-knot average, and it shows: calm conditions dominate before the sea breeze picks up around midday. By 3 p.m., expect gusts to touch 15 knots, which will kick up the wave range from a flat 0.1 meters near midnight to about 0.3 meters by afternoon. The swell is negligible at 0.14 meters from 205 degrees with a 2.2-second period, offering no real ride for surfers—the 4.5 score reflects that, in line with recent days. Paddlers should take advantage of the early morning glass; kayaking earns a 6.6, better than yesterday’s 7.6 but still workable if you launch before the wind builds. Wildlife watchers get a 6.5, helped by the waxing gibbous moon at 98 percent illumination and the minor period around sunset from 6:18 to 7:18 p.m., though low-tide timing isn’t available today. Visibility sits at 18 kilometers, and with no measured water clarity data, divers don’t get a score—but the 31.9-degree sea surface is bathwater warm. The real hazard is that 16:00 to 17:00 rain window: it’s narrow, but the air feels like 30 degrees Celsius under 87 percent cloud cover, so humidity will be sticky before any shower moves through. Compared to yesterday’s 8.7 boating score, today’s 7.4 reflects a bit more afternoon chop, but the stable 1016 hPa barometric pressure means no major fronts are rattling things. Looking ahead, Thursday keeps the seas flat with waves 0.1 to 0.2 meters and lighter peak winds around 13 knots, offering another solid morning for boating. Friday brings a spike in rain odds to 59 percent, and by Sunday the chance hits 86 percent with winds ramping to 18 knots, so this late-August stretch gets progressively unsettled. Your best bet: slide out before the lunch hour and you’ll find the bay as calm as it’s been all week.
