Light Winds, Sea Breezes Today
Alerts
A Marine Weather Alert is posted for all coastal waters. A long-period south swell will bring potential for moderate to heavy surges in harbors facing the south and may lead to waves breaking in and near harbor entrances (especially around low tide and during the morning hours). Extreme tide changes could lead to locally strong currents even in channel entrances. Boaters should be alert to larger than normal surf along south shores this weekend.
A High Surf Advisory is in effect through Monday at 6:00 p.m. for surf rising to 8 to 12 feet (with higher sets) along south facing shores. The swell is expected to peak Monday, then slowly fade Tuesday. Use caution when near the ocean during this time.
