Marine Weather and Tide Forecast for Miami Beach, 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.
