Marine Weather and Tide Forecast for Hollywood, FL

SHORT TERM
(Today through Tuesday)
Issued at 100 AM EDT Mon Oct 20 2025

The 00z MFL upper air sounding from earlier tonight as well as recent ACARS (aircraft data) soundings from South Florida airports depict quite a stark difference from the continental airmass (anomalously dry air with PWATs below the 10th percentile, comfortable dew points in the low to mid 60s) in place across South Florida last night to the tropical airmass currently in place (ample moisture with PWATs above the 90th percentile for this time of year, the return of humidity with dewpoints in the low to mid 70s)
tonight. Prior shower and thunderstorm activity over land has waned and dissipated over the last several hours, but 05z mesoanalysis indicates ample low-level moisture remains situated across South Florida early this morning. A developing nocturnal surface inversion combined with very light winds, clearing skies, and relative humidity values around 100% will result in the potential of patches of dense fog before and at daybreak across inland locales (highest probabilities for visibilities below 0.5 miles are around 40-60% near Lake Okeechobee) between 2am to 9am this morning.

As a mid-level trough lifts northeastward across the northeastern United States today, a distant surface low attached to the boundary will lose synoptic forcing while occluding. With the distant surface low weakening in strength, the attached sprawling frontal boundary that is draped across much of the western Atlantic waters and down into the Florida Peninsula this morning will lose forward motion.
The boundary will effectively come to a stop across Central Florida with light easterly to northeasterly flow prevailing across South Florida today. As South Florida remains in the warm sector of the boundary, a residual plume of low level atmospheric moisture (precipitable water values in the 1.6 to 1.8 inch category) will remain elongated across the region which may once again allow for a few diurnally driven (afternoon and evening) showers and isolated storms. Ample sunshine and light winds are forecast for most of today, with high temperatures remaining slightly above average across the region with forecasted highs in the upper 80s to low 90s area-wide.

As the stalled frontal boundary across Central Florida becomes frontolytic in nature during the day on Tuesday, enough residual low level moisture will remain to support the development of a few afternoon showers and perhaps an isolated storm or two. Temperatures will remain slightly above average for this time of year during this time frame with forecasted afternoon high temperatures on Tuesday afternoon reaching the upper 80s to low 90s.

LONG TERM
(Tuesday night through Sunday)
Issued at 100 AM EDT Mon Oct 20 2025

The subtropical jet and lobes of progressive mid-level troughing (due to a strong negative phase of the North Atlantic Oscillation)
will remain active across the eastern United States through much of the work week as several mid-level troughs amplify and advect eastward across the Great Lakes and northeastern United States.
Associated surface lows will also develop and advect from west to east across the Great Lakes region dragging sprawling frontal boundaries across most of the eastern half of the country, eventually arriving to the region and our surrounding waters.

A stronger frontal boundary during the second half of the week (Thursday into Friday) will veer winds to a northeasterly direction as a pressure gradient develops once again between the departing front and a large expansive area of surface high pressure across the southeastern United States. While a drier continental airmass is modeled to arrive across the region during this time frame, the breezy northeasterly winds may result in some vertically capped showers that periodically move onshore along the east coast from time to time. Breezy northeasterly winds late this week may once again set up a temperature gradient during the afternoon hours across the region, with the ocean breeze keeping the east coast cooler (low to mid 80s) than southwestern Florida (upper 80s to low 90s).

AVIATION
(06Z TAFS)
Issued at 100 AM EDT Mon Oct 20 2025

Light easterly winds will prevail at most terminals today with the exception of a gulf breeze developing at KAPF between 18-20z.
Isolated to scattered SHRA/TSRA is forecast to develop across the region this afternoon and evening. Reduced vis/cigs is possible in and around any SHRA/TSRA activity.

MARINE
Issued at 100 AM EDT Mon Oct 20 2025

Winds will remain light today, shifting from a southeasterly direction this morning to an easterly direction by this afternoon.
Wave heights will remain in the 2-4 feet range across the Atlantic waters today with seas in the 1-2 feet range across our local Gulf waters. A few showers and an isolated storm or two could develop across the waters once again today into tonight. If thunderstorm activity does indeed develop over the waters, erratic wind shifts and locally gusty winds could occur near and around any storms.

With the arrival and passage of the next cold front during the second half of the work week, another period of enhanced winds and waves is possible across the region, especially across the local Atlantic waters.

BEACHES
Issued at 100 AM EDT Mon Oct 20 2025

A high risk of rip currents will continue at all east coast beaches of South Florida through 8am this morning. As the risk of rip currents slowly subsides as the day progresses, the risk of high rip currents will remain at Palm Beach County beaches with a moderate risk of rip currents continuing at Miami-Dade and Broward beaches.

HYDROLOGY
Issued at 100 AM EDT Mon Oct 20 2025

The combination of higher than normal tidal levels due to the lunar cycle, enhancing onshore flow, and northeasterly swell will result in the continued potential of minor coastal flooding within 1.5 to 2 hours of high tide along the east coast today. A Coastal Flood Statement remains in effect for coastal Miami-Dade, Broward, and Palm Beach counties through this evening.
