Today across the East Coast of the United States, high pressure is building into the Mid-Atlantic while a weak frontal boundary shifts offshore in the Northeast. Along the New England coastline, west winds between 5 and 10 knots will shift to the northwest at 10 to 15 knots this afternoon with occasional gusts reaching 20 knots. Air temperatures are expected to reach a high in the mid 60s (°F) under partly cloudy skies. In the Mid-Atlantic and New York Bight, light northwest winds will give way to a southwesterly flow later today, with ambient temperatures climbing toward 65 (°F). Further south toward the Florida coast, east winds at 10 to 15 knots will transition to a southeast flow by the afternoon as temperatures peak near 78 (°F).
The average wave size across the Atlantic seaboard today remains manageable, with significant wave heights generally holding between 2 and 4 feet. Buoy data from the Rhode Island Sound indicates a primary southeast swell of 3 feet at a 6-second period, accompanied by a secondary southeast swell of 1 foot at 10 seconds. Offshore near Sandy Hook, New Jersey, the primary swell is coming from the south at 2 feet with a 6-second period, while a longer 9-second east swell is also present at 2 feet. To the south, Florida's coastal waters are seeing a southeast swell of 3 feet at 4 seconds.
Tidal transitions for the day include a morning low tide at 6:01 AM followed by a high tide at 12:53 PM in the northern sectors, while the southern regions will experience a high tide around 8:02 AM. Looking ahead to tomorrow, a backdoor cold front will sink south, bringing a shift to northeast winds and a slight increase in cloud cover, though marine conditions will remain steady with seas persisting at 2 to 3 feet.
