Marine Weather and Tide Forecast for Atlantic Beach, FL

SHORT TERM
(Sunday night through Tuesday night)
Issued at 153 PM EDT Sat Apr 19 2025

A low pressure system will begin to push into the Great Lakes region on Sunday evening. An associated cold front, extending southward of this low pressure system, will steadily move eastward across the southeastern CONUS during the first half of the upcoming week. By Tuesday night, the front will begin to move over the Appalachian mountains and stall to north of SE GA. As the cold front moves eastward, the ridge of high pressure will push off towards the western Atlantic, eventually sitting north of the Bahamas.

Dry conditions will remain in place across the area as high pressure will remain mostly in place. Southeasterly onshore flow will continue during the first half of the upcoming week as the high pressure shifts over the western Atlantic. Winds along the coast will range in the 10-15 mph range on Monday and Tuesday.
Monday, Highs for coastal locations will be in the lower 80s, compared to inland areas with highs mainly in the upper 80s, with some locations reaching into the 90s. By Tuesday, more inland locations will look to reach the 90F mark as onshore flow will help to keep coastal locations the mid to upper 80s. Overnight lows during this period will remain in the lower 60s for inland locations and the mid to upper 60s along the coast.

LONG TERM
(Wednesday through next Saturday)
Issued at 153 PM EDT Sat Apr 19 2025

By midweek, the frontal boundary is expected to remain stalled north of the local area as the high pressure over the western Atlantic begins to shift northeastward. With this pattern in place during the back half of the upcoming week, a south-southwesterly flow will bring moisture in from the Gulf. Question still remains if there will be enough moisture overhead to see the development of any showers or storms. Current guidance suggests relatively higher PWATs, ~1.25" to 1.30", for locations north of the I-10 corridor into SE GA. For those showers/storms that do develop will likely occur along the mergers of the Gulf and Atlantic sea breezes as a weak southerly flow will allow for both seabreezes to make their way inland.

Continuing the trend from Tuesday, most inland locations will likely see highs past the 90F mark and near the mid 90s potentially, leaving the door open for some daily record highs values through the end of the week. For locations along the coastal and towards the St. Johns River will be relatively cooler as the continuation of the southeasterly onshore flow will keep highs in the 80s. Lows will rise slowly from the low 60s inland into the mid 60s and to the upper 60s at the coast and along the St Johns river.

AVIATION
(18Z TAFS)
Issued at 113 PM EDT Sat Apr 19 2025

VFR with just a FEW fair weather Cu clouds to go along with gusty SE winds at 13-15G20-23 knots for the coastal TAF sites and 10-12G15-18 knots for the inland TAF sites. Winds fade again after sunset with increase in high clouds later tonight after 06Z which will likely prevent much in the way of significant fog formation and chances too low and will leave out of TAF forecast except for the usual MVFR vsbys expected at VQQ towards sunrise (07-11Z). Mix of high clouds and a FEW fair weather Cu clouds later in the TAF period from 12-18Z as SE winds increase once again, but likely a few knots weaker than today.

MARINE
Issued at 153 PM EDT Sat Apr 19 2025

No major changes expected as high pressure ridge axis will remain over or just to the North of the local waters through the upcoming week. A frontal boundary will approach from the Northwest during the middle of the upcoming week, but is expected to stall over the SE US states and very little impact is expected across the local waters. Daily sea breezes are expected around 15 knots across the nearshore waters with a mainly SE direction expected with some backing to the South during the overnight hours with speeds generally in the 10-15 knot range and seas of 3-5 ft, and while brief surges of winds to SCEC levels of 15-20 knots are possible, overall the marine forecast will remain headline free for the next 5 days.

Rip Currents: Moderate to High Risk of rip currents will continue today and Sunday as breezy onshore/Southeast flow will keep surf/breakers in the 2-4 ft range, along with increased crowds at the local beaches due to the above normal temps and Holiday weekend.



FIRE WEATHER
Issued at 153 PM EDT Sat Apr 19 2025

High pressure will remain over the area through the remainder of the weekend, continuing the breezy southeasterly winds along the coast on Sunday. Dry air remains overhead on Sunday, with inland min RH values in the 30-35 range, some spots of under 30 in far inland southeast Georgia, but higher min RH values expected along the coast.
By the start of the upcoming week, high pressure overhead will begin to shift away from the area. With the high pressure shifting away, coastal locations will continue to have light breezy southeasterly winds, but winds towards inland locations will see a shift to become southerly and light. Dry air will continue to remain over the area into the following week, with min RH values remaining in the 30% range for locations west of the I-95 corridor.
