KEY MESSAGES

- High pressure dominant across the area will continue to support an extended period of relatively unremarkable weather. - Generally moderate easterly breezes will prevail over the early week, eventually veering to the southeast sometime during the middle of the week. - Moderate drought continues for the entire island chain. Burn bans are possible, trees and bushes begin browning, and water supply decreases. For the upcoming week, there will be a slight chance for showers (10% to 20%).

FORECAST

High pressure centered near Bermuda will remain the main driver for the Florida Keys sensible weather through at least the middle of the week. The western side of this ridge extends over Florida and into the Gulf. This will continue to promote gentle to moderate mainly easterly breezes through Tuesday night. Low- level moisture will remain just enough to keep episodic showers remaining through mid week. Temperatures will remain above normal for this week with daytime highs in the lower 80s and overnight lows in the mid 70s.

Looking ahead at the extended, late this week, there remain signals for a cold front to potentially try and press southward along the Florida Peninsula. However, latest indications are for this front to be decaying as it approaches the Keys. That being said, its moisture is expected to remain across the area resulting in increasing rain chances through the period. In addition, instability will be increasing across the area along with ample upper level shortwave troughs traversing across the area embedded in the broader longwave trough. Therefore, thunder has been added to the forecast for Friday through Sunday. Dew points may also nudge down a few degrees making the change barely noticeable. Stay tuned!

Issued at 441 AM EDT Mon Mar 9 2026 There are currently no watches, warnings, or advisories in effect across the Florida Keys coastal waters. From synopsis, high pressure is centered near Bermuda with the western periphery of this ridge extending west into Florida and the Gulf. As the high retreats further into the Atlantic this week, breezes will shift to the east to southeast. A decaying frontal boundary is anticipated to drift southeastward across the Gulf late week which may create for a chaotic wind pattern across the Florida Keys coastal waters.
