FLORIDA EAST COAST MARINE WEATHER
Winds will shift N/NE Friday as high pressure builds over the lower Mississippi Valley in the wake of the frontal passage yesterday. Winds and seas will begin to diminish Friday afternoon into the evening as high pressure builds directly over the area. The weekend will be mostly sunny and dry, with seasonably mild temperatures. High pressure will shift southeast of local waters Saturday night, resulting in southwesterly winds developing on Easter Sunday, gradually strengthening through the first half of the work week.
7-DAY SURF FORECAST
FRIDAY: Wind lightest from the NNW/N early, becoming NNE/NE 9-16 mph later in the morning into early afternoon, then easing some later in the day with waves 1-2′ (+/-0.5′ with best size south) in mixed period (6-11 sec) NE/ENE swell.
SATURDAY: Wind light/variable early, becoming south 8-15 mph later in the morning through the afternoon with waves 1.5-2′ (+/-0.5′) in moderate to occ long period (8-10 sec) NE/ENE swell.
EASTER SUNDAY (31Mar): Wind lightest early, then increasing from the SW later in the morning, becoming south 7-13 mph in the afternoon with waves 1-occ 2′ (+/-0.5′) in diminishing moderate to long period (9-10 sec) ENE swell.

7-10 DAY WEATHER OUTLOOK
The last week in March strong high pressure over the New England region combined with a strong open ocean low retrograding south of Bermuda to provide a decent NE/ENE fetch that built the sizeable multi-day swell. Models suggest a similar scenario may play out again (further out in the Atlantic) April 11-14 when another low forms off New England then drops south while intensifying, then spins nearly stationary near Bermuda, meandering for several days as a weakening “cut-off” low in our ENE swell window. Surf temps north of the Cape that had climbed into the mid-60’s NE Florida and upper 60’s Daytona to NSB earlier in March will be held down into the mid-60’s through Easter into the first week of April, not seriously approaching the magical 70-degree mark until later in the month … stay tuned!
