Marine Weather and Tide Forecast for Cortez, FL

DISCUSSION
Issued at 107 PM EST Thu Mar 5 2026 High pressure remains aloft over the region with surface ridging also extending over the state from the Atlantic. This setup will generally remain in place through the weekend and into early next week, with low-level easterly winds becoming onshore with the sea breeze each afternoon. We will see rain chances just about every day, though probabilities vary based on available moisture. Best chances as of now are the rest of today and then Friday and Saturday afternoon/evening. Then as we head into early to mid next week, a trough will move into the deep south, with a surface low and accompanying frontal boundary moving into the southeastern U.S. by the end of the week, with increasing rain chances. Otherwise, rather humid conditions will prevail with highs running well above normal.

Model guidance continues to show some low clouds toward daybreak Friday morning, but the best chances look to be north of the Tampa Bay area so will leave out of the TAFs for now, with the exception of KLAL.
