Long Term
(Wednesday night through Monday) Issued at 104am EDT Tuesday September 23 2025

Seasonal conditions are expected Thursday and Friday with convection both days generally sea-breeze driven during the afternoon and early evening hours. Things get more interesting this weekend as a trough dives into the Gulf and a frontal boundary approaches the area and likely stalls in the vicinity of Lake Okeechobee. At the same time, a disturbance currently east of the Leeward Island has a medium chance of development over the next 7 days. While the surface front and upper level trough should steer any potential development away from South FL, some peripheral impacts could be possible if there is any development, so this system is worth watching as the week progresses. Regardless, the frontal boundary stalling in the vicinity of Lake Okeechobee will allow the atmosphere locally to remain fairly saturated which is what forecast soundings show, with PWAT (Precipitable Water) values generally 2.1-2.3 inches. Expect the unsettled weather to continue through the remainder of the extended forecast period.

Temperatures will remain slightly above normal through the extended period with highs each day in the upper 80s to lower 90s. Low temps will generally range from the lower 70s around the lake, to mid and upper 70s over the rest of South FL.

Marine
Issued at 104am EDT Tuesday September 23 2025

Gentle easterly winds expected over the area waters through mid week, with brief west to southwesterly winds during the afternoon over the near shore Gulf waters. Seas in the Atlantic generally 2-3 ft and a foot or less in the Gulf. Scattered thunderstorms today and Wednesday may result in locally hazardous winds and seas.

Beaches
Issued at 104am EDT Tuesday September 23 2025

Lingering NE swell will result in an elevated risk of rip currents through mid week for the Palm Beaches.
