Marine Weather and Tide Forecast for Aventura, FL

LONG TERM
(Sunday night through next Friday)
Issued at 145 PM EDT Sat Jun 21 2025

The weak mid level inverted trough will pull away from the region on Sunday night into Monday and the strong and expansive mid level ridge will basically remain parked across most of the Eastern Seaboard for the early to middle portion of the week. With the inverted mid level trough/vort max pulling further away from the region, South Florida will remain firmly entrenched on the southern periphery of this ridge for the early and middle portion of the week. At the surface, high pressure will continue to push westward and center over the Southeast and Mid Atlantic states through the middle of the week. This will keep moderate easterly wind flow in place across most of the region during the early portion of the week. However, wind will slowly start to diminsh by the middle of the week as the high starts to weaken a bit and the center shifts southward over the Florida Peninsula and western Atlantic.

The strong subsidence from the strong mid level ridge and surface high pressure will promote some drier air pushing into the region during the early portion of the week. This will help to bring the return of a typical summertime pattern to the region as convective development will once again be supported mainly by the sea breeze boundaries. With mid level temperatures gradually warming, strong thunderstorm chances will drop and will remain rather limited through the middle of the week. With east to southeasterly wind flow remaining in place, the highest chances of showers and thunderstorms will start out over the eastern half of the region in the morning before shifting towards the interior and west coast each afternoon. The strongest storms over the interior and west coast will still be capable of producing heavy downpours and gusty winds where sea breeze boundaries and thunderstorm outflow boundaries collide. High temperatures will range from the upper 80s along the east coast to the lower 90s across Southwest Florida.

Heading towards the end of the week, the uncertainty level in the forecast starts to rise as the latest ensemble and global guidance suite begins to diverge a bit as a weakening mid level low well off to the northeast tries to push southwestward closer to the region heading towards Thursday and Friday. This feature may try to push the strong mid level ridge a bit further to the west as the weakening low tries to sneak underneath the ridge and make it close enough to the region on Friday. This would help to enhance lift which would increase shower and thunderstorm coverage during this time frame. The latest guidance suite does differ with the evolution of this mid level low in regards to the timing and intensity as well as how close it actually gets to the region.
With this being towards the end of the forecast period, this also increases the uncertainty as well. For now, the latest forecast trends more towards climatology and keeps the diurnal summertime convective pattern in place with the highest chances of convection remaining over the interior and west coast each afternoon. This will continue to be monitored as the week progresses. High temperatures for the end of the week look to remain in the upper 80s and lower 90s across most areas.

A gentle to moderate east to southeasterly wind flow will continue across most of the local waters through tonight. These winds will gradually increase for the second half of the weekend and into early portion of the week especially across the Atlantic waters.
Seas across the Atlantic and Gulf waters will remain at 2 feet or less through the rest of the weekend. These seas will gradually increase early next week and could range from 2 to 4 feet with the highest seas remaining over the Atlantic waters. Scattered to numerous showers and storms will be possible each day. Winds and seas could potentially become hazardous in and around storms.

BEACHES
Issued at 145 PM EDT Sat Jun 21 2025

A moderate risk of rip currents will continue through the rest of the weekend across the Atlantic Coast beaches. As onshore flow increases early next week, a high risk of rip currents may develop across the Atlantic Coast beaches during this time frame.
