Marine Weather and Tide Forecast for Weston, FL

SHORT TERM
(Rest of today through Monday)
Issued at 233 PM EST Sun Dec 14 2025

The core of the eastern CONUS northern stream trough resides over the eastern Great Lakes region this afternoon, with an elongated ribbon of +PV energy associated with the southern stream draped from the Four Corners region through the Gulf. At the surface, the low associated with the northern stream wave sits off the NE coast, with high pressure centered over the Middle Mississippi Valley. Across Florida there sits two boundaries: one draped across south-central Florida, and the other moving through north Florida. The former sits in the trough extending southwest from the low off the NE coast, and the latter delineates the drier and colder continental airmass being ushered in on the leading edge of high pressure.

As this initial boundary move through South Florida today, scattered shower and a few storms will be possible. While there is plenty of instability and moisture in place, low-level flow is in the direction of the frontal movement and is limiting the available low-level convergence. The most robust storms that do develop are unlikely to produce any severe weather as effective shear generally remains below 20 knots, with unidirectional flow, and unimpressive lapse rates. The orientation of the low-level winds and the progressive nature of the front will likely preclude any localized flooding issues as well.

The bigger story with this frontal system will be the windy conditions we're expecting late tonight and through tomorrow, and the subsequent hazardous marine and beach conditions. The NAEFS and ECMWF ensemble systems depict that low-level winds could exceed climatological maximums tomorrow morning, with the ECMWF ensemble placing the wind event in the top 10 percentile of model forecasts for this time of year. What this equates to is about a 60% chance that wind gusts exceed 35 mph tomorrow, with a 10-20% chance of exceeding 40 mph. These top end values will be most likely along the east coast metros, with inland locations more likely to gust in the 20-30 mph range.

While Monday and Monday night will be the coolest days of the upcoming week, highs and lows will be generally near normal at their lowest. Expect mid 70s in the afternoon, and lows ranging from the mid 60s along the immediate coast, and closer to 50 across the Lake region.

LONG TERM
(Monday night through next Saturday)
Issued at 233 PM EST Sun Dec 14 2025

Through mid-week the upper level pattern will be dominated by multiple passing southern stream shortwaves that have little to no impact on the sensible weather as dry air will be abundant through the middle troposphere. As the low level ridge axis shifts south and east, a shallow layer of low-level moisture will remain under an E/ESE flow regime. Late in the week a northern stream wave will amplify the longwave pattern and bring another frontal system into the Southeast. This will be our next best chance for rain, but it will likely be of the hit-or-miss scattered variety. At this time there isn't a strong signal for much meaningful rainfall in the foreseeable future.

Highs and lows will gradually moderate back to the 80s in the afternoons, with near 70 degrees along the coasts each night.

AVIATION
(18Z TAFS)
Issued at 233 PM EST Sun Dec 14 2025

The main concerns for our terminals over the next 24-30 hours will be scattered showers and storms along a front this afternoon, winds and gusts increasing overnight and peaking tomorrow, and the potential for at least MVFR ceilings spreading across south Florida tomorrow morning through the day. Expect wind gusts tomorrow to be around 30 knots, however there are indications that, while not frequent, peak gust could near 35-40 knots (along the east coast) in a worst case scenario. Cool air advection over the Gulf Stream will likely bring a low cloud deck across south Florida tomorrow as well.

MARINE
Issued at 233 PM EST Sun Dec 14 2025

Winds shift northerly and increase behind a frontal passage today.
The period of strongest winds appears to be after midnight tonight through tomorrow afternoon. During that time, sustained winds are forecast to be between 25-30 knots with occasional gusts to low-end Gale force. Small Craft Advisories will be in effect starting this evening for all Atlantic, Gulf, and Lake waters. The Advisories will taper off to only the Atlantic waters by Monday night. Winds and seas should fall below hazardous levels by mid-week.

BEACHES
Issued at 233 PM EST Sun Dec 14 2025

The strong winds and large northerly swell will result in high surf along the Broward and Palm Beach coasts, while breakers will generally be 3-5 feet, occasional sets of 7-8 feet are expected.
Needless to say, the rip current risk is also expected to be high.
Surf conditions should improve by mid-week, but the rip risk may linger into late-week.
