KEY MESSAGES

- Mainly light to gentle breezes will continue through much of the remaining work week.

- Mainly dry conditions along with near-normal temperatures will also continue through Friday.

- Despite rainfall last week, drought conditions persist for the entire island chain. These conditions may worsen over the next several days due to lack of measurable rainfall for most locations.

MARINE

Issued at 207 PM EDT Tue Mar 24 2026

High pressure centered close to the Florida Keys and surrounding coastal waters will continue to dominate our winds through the next several days. This will entail breezes lulling during the late morning and afternoon hours, then peaking overnight. That being said, generally expecting breezes to peak at gentle to moderate, with the highest occurring across the Straits of Florida. This cycle of peak and lulls will continue through the end of the week. Thereafter, breezes will gradually undergo a freshening trend ahead of a potential weather maker over the weekend.

AVIATION

(18Z TAFS) Issued at 207 PM EDT Tue Mar 24 2026

VFR conditions expected with light northeast winds. Winds will increase overnight slightly, peaking around sunrise at near 10 knots, then decrease through Wednesday afternoon.

PREV DISCUSSION

Issued at 440 AM EDT Tue Mar 24 2026

Yet again another tranquil overnight persists, as KBYX continues to detect a lack of precipitation. Nighttime Microphysics satellite imagery indicates a thin boundary line of clouds across the Straits of Florida though nothing has sparked from it and elsewhere remains cloud free. Surface observations across the island chain show temperatures near 70F with dew points in the lower 60s. Marine observations along the Reef report light winds generally ranging from 5 to 10 knots. For today, similar conditions will once again persist. Stability in the atmosphere from the nearby high pressure will support mostly sunny skies, with near nil rain chances. Light to gentle northeasterly winds will potentially become variable during the afternoon as pressure gradient weakens.

Looking ahead to the rest of the week, high pressure will remain the dominate feature influencing the Keys, maintaining a dry and stable air mass. Therefore, minimal changes are anticipated through the next few days with continued low rain chances and mostly clear skies. In the extended period, a frontal boundary is projected to approach the region around Sunday. While significant temperatures variability is not currently expected with this front, it is likely to be accompanied by freshening of breezes, potentially reaching fresh to strong. Details in the forecast regarding timing and intensity will become more refined as it gets closer to time. Stay tuned!
