.FORECAST...
Issued at 442 AM EST Sat Nov 15 2025
A quiet week of weather is on tap for the Florida Keys. Surface
high pressure currently over the Southeast U.S. will drift south
along the Florida Peninsula through the remainder of the weekend.
As it does this, the high will weaken and flatten. This will keep
dry air entrenched throughout the area and much of the state
leading to nil rain chances for the foreseeable future. The
exception might be over the Straits where slightly deeper moisture
could lend to a shower or two. Gentle to moderate breezes this
morning, mainly over the marine area, will slacken as the
aforementioned high weakens later today. Daytime highs are
expected to be in the upper 70s with overnight lows in the upper
60s. With the light winds and generally clear sky, there is the
likelihood for radiational cooling across the Island Chain tonight
and Sunday night. Therefore, low temperatures were nudged down
some this update.

Another high pressure moving across the Southeast U.S. early next
week will lead to a strengthening of the pressure gradient across
the Keys. This will promote freshening northeast to east breezes
for mid to late week. This may also lead to a period of breezy
conditions once again for the Island Chain. Moisture remains
meager keeping rain chances near nil through the extended. As
winds also shift to the east, this will lead to slowly increasing
humidity and temperatures with daytime highs creeping back into
the lower 80s by late next week.

.MARINE...
Issued at 1018 AM EST Sat Nov 15 2025
There are currently no watches, warnings, or advisories in effect
across the Florida Keys coastal waters. From synopsis, high
pressure centered over the Southeast U.S. will continue to move
southward over the weekend. This will promote light to gentle
breezes. Due to the weak flow, there may be a period of light and
variable breezes Sunday through Monday, mainly in the afternoons.
Another high pressure system will traverse across the eastern
United States early next week while slowly strengthening. This
will allow for freshening northeast to east breezes through mid
week.
