Old Port Tampa, FL Daily Water Report — August 27, 2026

The best call on the water today is for divers and boaters, with morning offering the calmest conditions before an afternoon breeze kicks up. Diving scores a solid 7.6 out of 10, and with the surface nearly flat near dawn—wave heights bottoming out around 0.04 meters—getting below that 31.9-degree sea surface is a clean proposition. Visibility from the surface checks in at 19 kilometers, which is notably better than recent days, though remember that’s atmospheric, not underwater. The water clarity data that drives the diving score isn’t available separately, but the overall conditions favor getting in early. Boating earns an 8 out of 10, the best score of the day, with representative winds out of the south at just 5 knots gusting to 7. That’s well inside the comfort zone for most trailer boats and center consoles. The catch is timing: the wind range shows gusts could hit 18 knots by 3 p.m., and there’s a narrow rain window from 4 to 5 p.m. Aim to be back at the ramp by early afternoon and you’ll miss both the chop and the wet ride. Fishing sits at 7.3, a step down from yesterday’s 7.9. The solunar major period from 11:47 to 13:47 lines up nicely with the incoming tide, assuming the tide is moving—no tide data is available today, which is unusual and worth noting if you’re fishing structure. The waxing gibbous moon at 98% illumination will keep things bright through the night, but the midday bite window remains your best bet. Pressure is stable at 1016 hPa, which doesn’t signal any imminent barometric shift to spook fish. Compared to the last few days, today’s wind is a bit stronger than Wednesday’s 3.9-knot calm but still manageable. Surfing remains a 4.5, unchanged from the entire stretch—those 0.14-meter waves at a 2.6-second period are barely ripple territory. Kayaking at 7 is respectable, especially if you paddle before noon when winds are lightest and the rain window is still hours off. Looking ahead, Thursday brings similar calm seas but a chance of rain around 25%. Friday sees a 67% chance of precipitation with winds topping 12 knots. The weekend looks less promising: Saturday through Monday ramp up to 85% rain chances and winds gusting over 18 knots, and by Sunday the forecast shows flat seas—which sounds nice until you factor in the potential for thunderstorms rolling across the bay. If you’ve got one window, take the first four hours of daylight—before the south wind builds and the afternoon scatter starts.
