Marine Weather and Tide Forecast for Seville, FL

NEAR TERM
Issued at 209 AM EDT Wed Apr 30 2025

Some lingering moisture and calming winds could lead to pockets of radiation fog around sunrise mainly for areas west of I-95.
Strong high pressure remains off the coast of the southeastern seaboard causing east-southeasterly flow. Drier air (PWATs < 1 inch) over the I-95 corridor continues to spread westward encompassing the whole area by this afternoon. Drier air and subsidence will suppress any convection even with the sea breezes shifting inland. Highs will range from around 80 along the Atlantic Coast to the mid/upper 80s further inland. Overnight lows will range from the mid/upper 60s along the coast to the upper 50s/low 60s inland.

SHORT TERM
(Thursday through Friday night)
Issued at 209 AM EDT Wed Apr 30 2025

High pressure ridge axis from the Western Atlantic remains across the region with mainly dry conditions and a return to above normal temps with highs reaching into the upper 80s/near 90F over inland areas both days, while the East Coast sea breeze is expected to push inland to the US 301 corridor both days and should keep the Atlantic Coastal areas slightly cooler with highs into the middle 80s. Moisture levels increase slightly by Friday and may be enough to trigger an isolated shower and/or sprinkle along the East Coast sea breeze front as it moves inland, but overall rainfall chances will remain below 20%. Low temps are expected to fall into the lower/middle 60s over inland areas, while the onshore flow will allow temps to only bottom out in the upper 60s/lower 70s along the Atlantic Coastal areas. The dry airmass will not support significant late night fog formation, but patchy fog will be possible over inland areas just before sunrise on both mornings.

LONG TERM
(Saturday through Tuesday)
Issued at 209 AM EDT Wed Apr 30 2025

Saturday...Models in good agreement with next frontal boundary pushing into the local area from the Northwest and expect above normal temps into the 85-90F range prior to the onset of scattered showers and storms by the afternoon/evening hours, with a few strong storms with gusty winds/small hail possible, but significant severe weather is not expected.

Sunday into Monday...Models begin to diverge slightly, but overall pattern suggests that frontal boundary will stall across the FL peninsula with a low level breezy East to Northeast flow developing at the surface, while a disturbance moves aloft along the stalled frontal boundary which could develop a weak low pressure center off the NE FL coast. This set-up would lead to a return to near normal temps and increased rainfall chances with scattered to numerous showers and isolated storm activity, with best rainfall chances along the NE FL Coastal Counties, with lesser rainfall chances inland. Not much agreement in details between the wetter GFS and drier ECMWF solutions, so confidence definitely lower in forecast during this time frame.

Tuesday...High pressure likely builds into the Carolinas and nudges frontal boundary further southward and any low pressure development probably pulls away from the region. This will likely continue the breezy low level East to Northeast flow along with near normal temps. A few showers still possible along the coastal areas of NE FL/SE GA, but the remainder of inland areas should be mostly dry.

MARINE
Issued at 209 AM EDT Wed Apr 30 2025

High pressure will remain positioned off the southeastern seaboard through Friday. Winds decrease and shift to southeasterly early this morning through Thursday. A wind surge is expected on Thursday night well in advance of a cold front that will be entering the southeastern states on Friday afternoon and evening.
Caution conditions are likely for the coastal waters late this week. This cold front will cross our local waters on Saturday and Saturday evening, accompanied by showers and thunderstorms. A surge of northeasterly winds is forecast in the wake of this frontal passage on Sunday and Sunday night as high pressure wedges down the southeastern seaboard.

Rip Currents: Onshore flow will maintain a moderate risk of rip currents for area beaches through Thursday.
