CatchWindow fishing intelligence

Vaca Key, Florida Bay, FL Daily Water Report — October 5, 2026

Vaca Key gets a clear green light for boating today, with an 8.4/10 suitability score and generally manageable conditions for a wide range of water plans. The tradeoff is that it is not glassy: forecast waves run about 0.3 to 0.6 m, led by a short 0.52 m swell at 3.25 seconds from the southeast. That can put a little chop under smaller craft even while the east wind stays modest, generally 3 to 9 knots. The most useful daylight window begins around the 7:57 AM high tide and overlaps the 8:15–10:15 AM solunar major period. That is the day’s strongest fishing opportunity, though the fishing score is a respectable rather than spectacular 6.5/10. Pressure is falling from around 1015 hPa, and the tide then drains steadily toward the 6:30 PM low, so plan for changing water depth rather than treating the morning high as an all-day condition. Boaters should find a notably easier day than the breezier start of last week: today’s representative 6-knot wind is well below the 15.2 knots recorded in CatchWindow’s reconstructed October 1 history. Kayaking earns 7/10, but the roughly 0.53 m/s ocean current toward 338 degrees deserves attention; light wind does not cancel moving water. Sailing rates 7.5/10, with enough breeze for a pleasant outing but not much reserve for those hoping for a hard-working sail day. The afternoon is hot and humid, with air temperatures reaching 31.1 C and a feels-like reading near 30 C. No rain window is indicated, cloud cover is minimal, and atmospheric visibility is forecast near 16 km. That visibility figure says nothing about underwater clarity, and no diving score is available today, so diving conditions are best left ungraded. The evening low tide arrives before sunset at 7:09 PM, while the next solunar major period runs 8:15–10:15 PM. The calmest forecast seas do not arrive until near 11 PM, around 0.26 m, after daylight has gone. The next three days look exceptionally smooth on the marine forecast, with waves mostly 0.1–0.3 m through October 8; winds strengthen again October 9–11, with waves building to 0.6–0.7 m by the 11th. Best bet: launch after dawn, work the high-tide morning window, and be back before the afternoon heat turns the cockpit into a skillet.
