Marine Weather and Tide Forecast for Fort Pierce, FL

DISCUSSION
Issued at 229 PM EST Sun Dec 14 2025

Rest of Today-Monday... The upper level low pressure over the Great Plains will move into the Great Lakes region today before deepening and moving eastward towards Maine through Monday. At the surface, a strong high pressure centered over the Midwest will shift southward into the Deep South on Monday with the axis building over the Florida peninsula. The frontal boundary across South Florida will lift northward as a warm front today, increasing the moisture across the southern portions of the CWA Forecast PW values will range from 1.0-1.1" across the north to 1.2-1.5" across the south.
This will result in an increase in cloud cover as well as a return of rain chances across the local area. There is a low to medium (20- 60 percent) chance of rain from southern Brevard/Osceola southward today, with the greatest potential for rain occurring across the Treasure Coast and around Lake Okeechobee into early afternoon.
There remains a low (20 percent) chance of lightning storms mainly across the Treasure Coast and southern Okeechobee county today. Rain chances push offshore late afternoon and overnight, remaining mostly dry over land areas on Monday.

The next cold front will push across east central Florida this evening into tonight. This will be a dry frontal passage, with no mentionable rain chances through Monday. However, winds will increase across the local area tonight into Monday as the axis of the strong high pressure builds over the Florida peninsula, tightening the pressure gradient and resulting in a period of windy conditions (especially along the coast). North to northwest winds at 5-10 mph today will increase to 15-25 mph across the interior and 20- 30 mph with gusts up to 40 mph possible along the coast tonight into Monday with winds shifting north to northeast on Monday. A Wind Advisory has been issued along the coast starting at 7pm tonight.
The high pressure will steadily weaken on Monday, which will allow the pressure gradient to loosen somewhat over the local area. This will result in the north to northeast winds decreasing, however, they will remain breezy/gusty especially along the coast.

These strong winds will also result in rough, pounding surf and minor beach erosion tonight into Monday. Breaking waves of 7-9 FT are forecast, briefly up to 10 FT along the Volusia coast. Thus, a High Surf Advisory has also been issued. The high tide of most concern will be early Monday between 4am-5am. A High risk of rip currents goes into effect later this afternoon from Cape Canaveral northward, spreading to all the coast Monday.

Temperatures will be above normal on today before becoming noticeably cooler behind the front on Monday. Afternoon highs will be in the upper 70s to low 80s today before dropping to low to mid 60s across the north and upper 60s to low 70s across the south on Monday. Overnight lows will range from mid to upper 40s across the far north to low 60s across the far south tonight, and range from low to mid 40s across the far north and near 60 degrees across the far south on Monday night.

Tuesday-Thursday... A weakening high pressure across the Deep South will move into GA early on Tuesday before gradually shifting eastward, moving offshore into the Atlantic ocean by Thursday. The trailing axis will remain over the Florida Peninsula through the time period. This will result in north to northeast winds turning easterly on Tuesday at 5-10 mph as the high settles into the Deep South before eventually veering east to southeast Wednesday evening and continuing through Thursday as the high moves offshore.

Today-Thursday... (Modified Previous Discussion) Conditions will begin to deteriorate this afternoon and especially this evening/overnight as strong high pressure builds over the area behind a cold front, tightening the pressure gradient over the local area. North winds increase 20-25 knots by sunset across the northern (Volusia) waters will overspread the remainder of our coastal waters this evening with rapidly building seas especially in the Gulf Stream. A Gale Warning has been posted for the Volusia Atlantic waters for frequent gusts to gale force (34 knots) while solid Small Craft Advisory conditions will exist elsewhere with occasional gusts to gale force possible. Seas will build rapidly to 13 FT in the Gulf Stream tonight into Monday with 7-10 FT nearshore.

The high pressure will weaken as it settles into the SE US Monday so wind speeds will drop below 20 knots Mon aftn but seas will be slower to subside given the NE wind component. The high will push seaward through mid week and winds will veer east then southeast in response and the pressure gradient supporting 10-14 knots. It will take a little while for seas to subside below 7 FT in the Gulf Stream so have extended the SCA there slightly. But once we lose the north wind component, seas will subside below 6 FT Tuesday night and below 5 FT Wednesday. Seas nearshore will be 3 FT Wednesday- Thursday as winds develop a SE component.
