Marine Weather and Tide Forecast for South Palm Beach, FL

SHORT TERM
(Today through Friday)
Issued at 227 AM EDT Thu Apr 16 2026

Benign weather conditions will prevail through the short term period as ridging remains established over the Gulf waters. This ridge of high pressure will help continue to promote subsidence across South Florida; that, along with an anomalous mass of dry air aloft (as evidenced by the 00z MFL sounding and ACARS data from KMIA/KFLL/KPBI), will help inhibit any mentionable chances for precipitation across the area today. Some moisture will begin to filter in near the surface on Friday, which could allow for some nuisance showers to form over the local Atlantic waters and the immediate East Coast. However, no appreciable rainfall accumulations are expected at this time.

With easterly winds near the surface and persistent subsidence, temperatures will continue to warm up as we head into the weekend.
Highs today and on Friday will reach the upper 80s and lower 90s over the southwest and interior FL, while they'll most likely cap out in the low 80s along the East Coast. Lows each day will drop into the 60s across the interior and low 70s along the coasts.

LONG TERM
(Friday night through Wednesday)
Issued at 227 AM EDT Thu Apr 16 2026

Conditions will remain generally unchanged over the weekend, but a gradual pattern change will begin to take hold across the continental US, which could result in unsettled weather early next week.

Aloft, an upper-level trough will begin to dig across the Plains and the Eastern Seaboard this weekend, eroding the ridge over the Gulf and weakening the surface high. This gradual process will allow for some moisture to filter back into the region, with models PWATs surging back to near normal values for this time of the year (1.1- 1.3 inches). This could allow for some isolated rainshowers to develop Saturday and Sunday afternoons, especially along any sea breeze boundaries that manage to develop.

Conditions could begin to deteriorate early next week as an attendant surface low associated with the upper-level trough develops and moves across the Great Lakes region. As it does, it will drag a cold front south towards the Florida peninsula. Most model guidance shows this front dropping along the peninsula early in the week, clearing the area by midweek. Ahead of the front, chances for rainfall increased across the region, especially Monday evening and Tuesday. However, much uncertainty remains with this solution; a deeper, faster trough (and thus a stronger, faster front) could result in generally drier conditions for our area, while a slower, weaker trough could lead to higher QPFs for the region. For now, the NBM supports a slightly deeper, faster solution with 30-40% PoPs each day, and QPFs less than 1 inch. We will continue to monitor this solution as the forecast evolves.

Above average temperatures will be likely this weekend as weak easterly flow prevails, with highs in the upper 80s and lower 90s each afternoon. Conditions could cool back down to more seasonable temperatures once the front moves across the area, with highs next week in the upper 70s and lower 80s. Lows each night could dip into the 50s across the interior, and down to the 60s along the coasts.

AVIATION
(12Z TAFS)
Issued at 653 AM EDT Thu Apr 16 2026

VFR conditions should prevail through the period. Easterly winds will persist, ranging from 5-10 kts early this morning, and increasing up to 10-15 kts late morning into the afternoon. At KAPF, a Gulf breeze will develop, with westerly winds moving ashore. Winds should become light and variable overnight.

MARINE
Issued at 227 AM EDT Thu Apr 16 2026

A moderate breeze will prevail across the local Atlantic waters as high pressure remains in place over the region. Lighter winds will set up over the Gulf waters. Seas will drop to 2-4 ft in the Atlantic and remain 2 feet or less in the Gulf. Another period of breezy, hazardous conditions could approach early next week with the passage of a cold front.

BEACHES
Issued at 227 AM EDT Thu Apr 16 2026

Strong onshore flow will promote a high risk of rip currents across the Atlantic coastline through Friday.
