Marine Weather and Tide Forecast for Big Pine Key, FL

AVIATION
(18Z TAFS)
Issued at 128 PM EDT Sat Apr 11 2026 VFR conditions will prevail at both EYW and MTH through the TAF period. Some light showers are possible but not expected to impact either terminal at this time, therefore no mention of VCSH at either terminal. Near surface winds will continue to be easterly with gusts of near 25 knots.

PREVIOUS DISCUSSION
Issued at 600 AM EDT Sat Apr 11 2026 Surface analysis places a 1026 mb high pressure system centered over the Eastern Seaboard. This feature, interacting with a weak frontal boundary extending from the western Caribbean northeastward to the central North Atlantic, continues to support fresh to strong northeast to east breezes across the Florida Keys and the adjacent nearshore and offshore marine zones. KBYX Doppler radar is detecting isolated nocturnal showers owed to the moisture fluxes across the now near 80F surface temperature waters, although nearly all showers are light in nature. Current surface temperatures are in the lower 70s across the Island Chain at this early Saturday morning hour.

A rather stagnant and mundane forecast is in store for the next seven days across the Keys. The aforementioned high pressure system will slowly migrate eastward into the west-central North Atlantic over the next several days. The associated ridge axis will remain well north of the Florida Keys, supporting continued breezy to windy conditions. Isolated showers will be slightly favored in the overnight and early morning hours, although total rainfall amounts will generally be light. Moderate drought conditions will likely continue ahead of the upcoming wet season.
Temperatures will be at or just above normal through the end of the work week, with highs in the lower 80s, and lows in the lower 70s.

MARINE
Issued at 1136 AM EDT Sat Apr 11 2026 A Small Craft Advisory is in effect for all of the Florida Keys waters. From synopsis, a strong high pressure system over the Eastern Seaboard will maintain fresh to strong breezes through early next week. As is typical in this pattern for April, passing light fast-moving showers cannot be ruled out, especially in the overnight periods.
