Marine Weather and Tide Forecast for Palm Beach Shores, FL

SHORT TERM
(Today through Friday)
Issued at 403 AM EDT Thu Mar 19 2026

Models depict a lingering mid lvl trough over the eastern seaboard, while sfc high pressure dominates the SE CONUS and the northern half of the Florida peninsula. Closer to SoFlo, a stationary decaying frontal boundary will remain lingering the central Cuba-Bahamas area. Several shortwave impulses can be seen moving along the base of the trough, but any upper lvl enhancement they could provide will remain well north of the area. Combined with increasing pressure gradients bringing breezier northerly winds, expect the current stratiform cloud decks to finally begin pushing southward into the Florida Keys by the late morning hours.

While the air mass is not expected to significantly dry out today, atmospheric stability and lack of lifting will reduce POPs in general to single digits this afternoon across much of the area. NBM and high-res solutions suggest some late afternoon marine showers drifting into the Palm Beach/Lake region, which will be kept in the grids for now. Some increasing moisture advection may result in low- end coverage along east coast areas with isolated to scattered passing showers during the evening hours. These coastal showers will likely continue through Friday morning as winds slowly veer to the NE. Then moisture finally decreases enough for showers to end and a dry period to begin Friday afternoon.

The decreasing cloud cover should allow for better daytime heating today. High temps this afternoon will be in the mid-upper 70s across SoFlo, warmest over west coast locations.

LONG TERM
(Friday night through Wednesday)
Issued at 403 AM EDT Thu Mar 19 2026

Models show ridging expanding across the Gulf and stretching into the state, remaining in place through early next week with partly cloudy to mostly clear skies each day. The ridge axis will linger over the region with winds becoming light and variable at times. It will also allow for afternoon temps to go back into the mid-upper 80s by the weekend, a trend that will persist through the rest of the long term.

The dry pattern seems to begin modifying by mid week a as a frontal boundary stalls over the SE CONUS while pushing the ridge further into the west Atlantic. This will allow for moisture to gradually return to SoFlo, but with best POPs likely remaining in the 15-20 percent range at best.

AVIATION
(06Z TAFS)
Issued at 123 AM EDT Thu Mar 19 2026

Periods of MVFR/IFR cigs conditions continue through around 10Z under decks of cu/stratocu still streaming across the area, mainly the Atl terminals. -SHRA will also accompany the periods of low cigs at times. NNE winds at 10-15 kts will become gusty after 15Z.
