Marine Weather and Tide Forecast for Key Vista, FL

UPDATE
Issued at 703 PM EST Sun Jan 18 2026

Early evening IR and water vapor satellite imagery are showing drier air and clear skies filling into northern Florida in the wake of the cold front that is now pushing through southern Florida, while layers of stratus that are still covering much of the forecast area gradually push south. Along and just behind the front, strong and gusty winds were felt across the forecast area today, but automated surface observations are showing that these winds have now significantly calmed down. However, winds overnight are still strong enough to continue the cold air advection that started with the frontal passage earlier today, with temperatures still on track to drop into the upper 20s to mid 30s over the interior by Monday morning, and upper 30s to low 40s along the coast. A Cold Weather Advisory remains in effect for the entire area tonight, with a Freeze Warning in effect for Polk County and interior portions of Hillsborough and Pasco counties northward.

The forecast looks on track overall, and no significant changes are planned for the evening update.
