Vaca Key, Florida Bay, FL Daily Water Report — October 8, 2026

Vaca Key gets a clear green light for small-boat time and a qualified yes for paddlers and divers: this is a notably gentle water day, though the afternoon breeze and current deserve more respect than the wave height suggests. Boating leads the board at 8.2/10, with diving at 8.1 and kayaking at 7.6. Those are suitability estimates, not a substitute for seamanship, local knowledge, or a proper float plan. The best all-round window is early through late morning, before the day’s strongest wind and gusts arrive around 1 PM. Winds range from nearly calm to 9.5 knots, with the strongest gust forecast near 11.9 knots, while waves stay a modest 0.2 to 0.3 metres. The calmest seas are forecast near midnight at 0.22 metres, but daylight users should still find a forgiving surface through much of the morning. The short 3.1-second wave period means these are small, close-together waves rather than long rolling swell—usually manageable, but capable of adding a little chop once the southwest wind fills in. For fishing, the 6.6/10 outlook is steady rather than spectacular. Pressure is rising from around 1011 hPa, and the strongest solunar major period runs 10:44 AM to 12:44 PM, conveniently close to the 1:39 PM high tide. A second major period arrives late, from 10:44 PM to 12:44 AM. The shallow tide range—0.25 metres at the 5:01 AM low to 0.40 metres at the afternoon high—means subtle water movement, not a dramatic tidal push. The 0.61 m/s ocean current toward 346 degrees remains a real planning factor for paddlers, divers, and anyone anchoring or drifting. Diving rates well on the light wind, low waves, available clarity inputs, and warm 30.1 C marine SST, but atmospheric visibility of 16.7 km is not an underwater-visibility reading. The water is also running 0.9 C above average. Fishing is similar to the last few days, while boating is a touch below yesterday’s 8.4 but remains strong; sailing slips to 5.9 because there simply is not much wind to work with. Friday begins a rougher, more unsettled stretch, with waves building to 0.3–0.7 m and rain chances rising. Saturday and Sunday look bumpier still, before conditions ease again next week. Best bet: launch early, use the late-morning solunar window, and be headed home before the afternoon breeze decides it wants a vote.
