Marine Weather and Tide Forecast for South Miami, FL

SHORT TERM
(Today through Thursday)
Issued at 119 AM EDT Wed Jun 18 2025

A stagnant weather pattern continues for the next couple of days as a stout mid-level ridge is centered in the western Atlantic and extends over the South Florida region, along with surface high pressure in the western Atlantic. This will maintain a steady easterly to southeasterly wind flow across the region and focus afternoon convection towards the Gulf coast areas as the sea breezes develop. A few showers will be possible for east coast metro areas early in the day and at night due to coastal convergence, but then this shifts away from there and towards the Gulf coast areas by midday through the evening. Given the ridge's presence, not expecting many thunderstorms both today and tomorrow even during peak heating hours, but an isolated storm or two will still be possible for Gulf coast areas.

High temperatures will be mostly in the low to mid 90s across the region except for coastal locations along the Atlantic that peak in the upper 80s. Maximum heat index values will be in the 100-105F range.

LONG TERM
(Thursday night through Tuesday)
Issued at 119 AM EDT Wed Jun 18 2025

Global long range solutions, especially GFS, show sfc ridging dominating the region, with its ridge axis lingering over central Florida through the weekend. Aloft, high pressure also remains in place with a very modest increase in atmospheric moisture for the second part of the work week. Therefore, expect a typical summer weather pattern to continue during the long term with sea breeze circulations becoming the main mechanism for potential deeper convection and thunderstorms each afternoon. In addition, early morning coastal showers will also continue, embedded in the synoptic ESE flow each day.

For the upcoming weekend, model consensus remains poor regarding a possible upper level disturbance moving westward just south of the peninsula. Meanwhile, GFS/EURO guidance show an amplifying mid/upper trough deepening across the E CONUS. While either of these features could modify the dominating high pressure system in place, there is enough uncertainty in guidance regarding the chances of these features having a significant impact on the long term forecast philosophy. Therefore, changes to the POPs/Wx grids for the weekend weather will be kept to a minimum at the moment and will wait for upcoming model guidance before deviating from the current forecast scenario.

Generally warm temperatures will continue across SoFlo, with afternoon highs in the low-mid 90s inland, and upper 80s to low 90s near the coasts. Overnight lows will likely remain in the low 70s inland, and in the upper 70s to around 80 across near the coasts.

AVIATION
(12Z TAFS)
Issued at 806 AM EDT Wed Jun 18 2025

A few SHRA with brief MVFR ceiling/vsby will affect some east coast terminals through about 16z, otherwise prevailing VFR. More numerous SHRA/TSRA developing interior and SW Florida from 18z-00z. PROB30 for TSRA with MVFR at KAPF included from 20z-00z.
Wind 120-130 degrees 10-13 knots, gusting to around 20 knots through 00z, except SW seabreeze at KAPF 18z-00z.

MARINE
Issued at 119 AM EDT Wed Jun 18 2025

A gentle to slightly moderate E/SE flow will continue for the next few days as high pressure remains in control of the western Atlantic. Any thunderstorm that forms may produce periods of gusty winds and rough seas. Seas will be generally 2 feet or less across the local waters.

BEACHES
Issued at 119 AM EDT Wed Jun 18 2025

Rip current risk will remain moderate across all Atlantic beaches through the end of the work week as ESE flow persists.
