Marine Weather and Tide Forecast for Tamiami, FL

LONG TERM
(Sunday night through Friday)
Issued at 320 AM EDT Sat Apr 19 2025

As we move into the new week, the west Atlantic high and mid-level ridging will maintain a stronghold of our weather with dry and stable conditions continuing. Pressure gradients tighten which will lead to potential for breezy conditions across the east coast metro and Atlantic waters. There will not be a sufficient increase in the moisture levels with the air mass still projected to be too dry for precipitation. Model guidance continues to forecast approximately 50- 70% of normal precipitable water and afternoon dew points in the low 60s in South Florida. Therefore, even with the easterly sea breeze and warm temperatures, conditions are expected to remain dry and stable throughout through most of the week. There continues to be no clear return of much needed moisture and rain, via sea breeze nor frontal passage, in our extended forecast. The NBM continues to hint at potential for isolated light rain on Friday or Saturday with ~15- 20% PoPs. No agreement among model guidance about the likelihood for rain, but the strong easterly winds may help if there is any increase in moisture. High temperatures will warm into the mid-to- upper 80s across a majority of the region, with a potential for above normal low 90s across much of the interior southwestern Florida. Overnight temperatures will be cool and comfortable, with outgoing longwave radiation and little sky coverage, allowing for lows to drop into the 60s, except low 70s along the east coast. With dry air and very dry fuels regionwide, winds and RH values will be watched carefully as the conditions will be prime for ignition and rapid burns.

AVIATION
(06Z TAFS)
Issued at 131 AM EDT Sat Apr 19 2025

VFR will prevail through the TAF with no rain in the forecast.

MARINE
Issued at 320 AM EDT Sat Apr 19 2025

As mentioned above strong easterly winds are expected through the weekend. This will create hazardous boating conditions across both the Atlantic and Gulf waters. Advisory conditions are expected through Sunday night for both coasts, with both wind and wave criteria being met along the Atlantic side. While Advisory conditions should subside on Monday, periods of Cautionary conditions are expected through next week.

BEACHES
Issued at 320 AM EDT Sat Apr 19 2025

A high rip current risk will remain in effect along Atlantic beaches through at least early next week. Strong easterly winds and elevated surf will create life threatening swimming conditions, especially for inexperienced ocean swimmers. Portions of the Broward and Palm Beach coasts may sea breakers near 7 feet this weekend as well. For now, surf is expected to remain just below advisory levels.

FIRE WEATHER
Issued at 320 AM EDT Sat Apr 19 2025

A couple days of low relative humidity coupled with higher than usual winds has prompted the SPC to place the western half of south Florida under an Elevated fire weather risk. While dewpoints will remain mostly uniform across the region, the warmer western half will result in humidities dropping to 35-40% today and tomorrow. At this time a Red Flag warning is not necessary as there's only about a 20% chance of meeting criteria, and even then it would remain a marginal event. With that said, caution should be exercised over the coming days. Keep in mind that county-enacted burn bans remain in place across much of western south Florida as well. Dispersion indices will be over 90 for each afternoon this weekend.
