Marine Weather and Tide Forecast for Southwest Ranches, FL

SHORT TERM
(Today through Tuesday)
Issued at 218 AM EDT Mon Mar 16 2026

Surface analysis early this morning shows a stout low-level cyclone traversing across the Great Lakes area while dragging a strong cold front across the Plains. This complex will continue to progress eastward today, with the front forecast to slide south along the peninsula and reach our area later tonight. Isolated shower and thunderstorm activity will be possible ahead of the front today, especially across portions of the East Coast metro where instability, shear and forcing will be maximized. Some of these storms could be strong to severe in nature; there's a Marginal Risk (Level 1 of 5) of damaging winds (> 60 mph) and quarter-sized hail for portions of the East Coast metro this afternoon. Isolated street flooding could also be possible.

There remains some uncertainty regarding the frontal approach later tonight, with models ping-ponging on its health and the potential for convective development as it moves across the area. For now, went with the solution that maintains some level of frontogenesis and brings the line of showers and storms across the region between 8PM-2AM. Some of those storms could bring heavy rain and gusty winds, but chances for severe impacts associated with the line look pretty meager at this time, and given the speed of the line, hydro concerns also remain limited.

The front is forecast to clear the area by early Tuesday morning.
Northerly flow behind the front will bring a cooler airmass across the region. Moisture along the column will remain somewhat elevated, which could result in sparse showers and a few thunderstorms over the local waters and the immediate southeastern coast throughout the day.

Abnormally warm temperatures in the mid to upper 80s will continue today as southerly flow continues to advect warmer, moist air over the region. Temperatures will struggle to rise above the 60s on Tuesday once the front clears the area and the cooler air mass moves over the region.

LONG TERM
(Tuesday night through Sunday)
Issued at 218 AM EDT Mon Mar 16 2026

Northerly flow will prevail across the area, promoting cooler conditions through the end of the week. Overnight temperatures Tuesday and Wednesday nights will drop to the upper 40s and lower 50s across the interior, and low 60s along the East Coast. Daytime temperatures for the rest of the week will remain in the comfortable 70s, gradually rising to the 80s over the weekend.

Model guidance shows the aforementioned front lingering over the FL straits and western Caribbean waters on Wednesday. Its presence near our area will help maintain moisture in place along the atmospheric column, keeping chances for showers and a few thunderstorms in the 30-40% range for portions of the East Coast metro on Wednesday and Thursday. The front is forecast to dissipate come Friday, and surface high will build over the region, ushering dry, sunny conditions in time for the weekend.

AVIATION
(06Z TAFS)
Issued at 218 AM EDT Mon Mar 16 2026

SHRA/TSRA will be possible throughout the day today as a cold front approaches, and could result in brief periods of sub-VFR conditions across East Coast terminals, especially between 18-22Z, and then again between 00-06Z. Southerly winds will prevail today, but will gradually veer out of the west, then the northwest overnight as the front moves through.

MARINE
Issued at 218 AM EDT Mon Mar 16 2026

A moderate to breezy southeasterly breeze will prevail across all local waters today ahead of a frontal approach late tonight. Seas will remain below 3 feet across the Gulf waters, and between 3-5 feet across the Atlantic waters. Scattered to numerous showers will be possible across all local waters today, with potentially rough seas and strong winds near any storms. Winds will increase out of the north behind the front on Tuesday, resulting in hazardous conditions through the end of the week.

BEACHES
Issued at 218 AM EDT Mon Mar 16 2026

Palm Beach and Broward county beaches will be at high risk of rip currents today as northerly swell persists.
