Marine Weather and Tide Forecast for Palm Beach Shores, FL

SHORT TERM
(Today through Sunday)
Issued at 105 AM EDT Sat May 9 2026

Mid level high pressure is over western Cuba this morning and will slide to the northeast over the Bahamas on Sunday. Meanwhile at the surface, a stationary boundary remains over northern FL. This frontal boundary is expected to dissipate by the end of Sunday.

The main story this weekend will be the heat and humidity. Light southerly winds will allow low level moisture to slowly increase throughout the weekend. Dewpoints near the coasts will be in the low to mid 70s and upper 60s to lower 70s over the interior. 850 mb temps will be roughly +18 to +20C. Afternoon high temps today and Sunday will be in the lower 90s across the east and west coast metro areas, with mid to upper 90s over the interior. The heat combined with the humidity will result in afternoon heat indices over 100-105 over much of the area. While heat headlines are not expected at this time, this early season heat and humidity will still result in major to locally extreme impacts across the metro according to the NWS experimental HeatRisk. Anyone with outdoor activities will want to take precautions to protect against the heat.

Most of today will remain rain-free, however some late day showers and isolated thunderstorms may pop up along the sea breezes. As low level moisture increases further on Sunday, there will be a better chance for showers and storms during the afternoon and early evening, especially over interior locations.

LONG TERM
(Sunday night through Friday)
Issued at 105 AM EDT Sat May 9 2026

Early next week, an upper level trough will eject out of the southern plains and move across the Gulf, with the trough axis eventually moving east of our region by mid week. This trough will also help push a frontal boundary across the area late Monday into early Tuesday, eventually settling south of the area over the Straits. This will keep the threat of showers and thunderstorms in the forecast through at least Wednesday, with drier conditions expected for the end of the work week.

Temperatures are expected to remain above normal next week, with highs generally ranging from the upper 80s to lower 90s across the metro, to low and middle 90s over the interior. Overnight lows will be in the 60s/70s.

AVIATION
(06Z TAFS)
Issued at 105 AM EDT Sat May 9 2026

Light and variable winds this morning becoming SE 10-15 kts this afternoon, with a westerly Gulf breeze this afternoon at APF. An isolated thunderstorm is possible late in the day.

MARINE
Issued at 105 AM EDT Sat May 9 2026

Mostly benign marine conditions this weekend with gentle to moderate southerly winds. An isolated thunderstorm can't be ruled out. Seas generally a foot or less in the Gulf and 2 ft or less in the Atlantic.

FIRE WEATHER
Issued at 105 AM EDT Sat May 9 2026

Min RH values over interior South FL will fall into the mid to upper 30 percent range this afternoon. While winds will remain light and RH values should remain above critical thresholds, the hot and dry conditions combined with very good to locally excellent dispersions may result in an enhanced fire risk this afternoon over interior locations.
