🌊 US Weather Warriors MarineCast — Saturday, June 13, 2026
Small Craft Advisory up on the Chesapeake and Coastal Flood Advisory along the Delaware/NJ beaches — pick your spots carefully today.
Today on the Water: SCA in effect on the Chesapeake through 8:30 AM, with advisory conditions expected to redevelop and run through tomorrow night. Coastal Flood Advisory runs through 5 PM today for Delaware and South Jersey beaches and inland Sussex. Radar is quiescent across the region right now, but the bigger marine punch arrives Sunday with south winds gusting to 25 kt and seas building.
Atlantic Coastal Waters (Lewes → southern VA coast): Conditions today are the calm before the front. By Sunday night, expect S winds 15-20 kt shifting SW 10-15 kt after midnight, gusts to 25 kt, seas 3-4 ft and occasionally to 6 ft with showers and a chance of thunderstorms. If you go out, get back to the dock well before sundown Sunday.
Delaware Bay: Light flow today, then S 5-10 kt building to 15-20 kt with gusts to 25 kt Sunday afternoon. Seas climb from a foot or less to 2-3 ft as the southerly fills in. Chance of showers and thunderstorms Sunday afternoon.
Chesapeake Bay & Delmarva-facing Waters: SCA in force through 8:30 AM on the upper and middle Bay. Sunday brings S 5-10 kt with gusts to 15 kt early, ramping to SE 15-20 kt with gusts to 25 kt in the afternoon. Showers and thunderstorms possible — Special Marine Warnings may be needed.
Wind & Seas Outlook: Peak winds Sunday night: S 15-20 kt, gusts 25 kt. Peak seas Sunday night offshore: 3-4 ft, occasionally to 6 ft. Calmest period is Monday night into Tuesday.
Marine Alerts:
- Coastal Flood Advisory — Delaware Beaches, Inland Sussex, Cape May, Atlantic Coastal Cape May, Cumberland — until 5 PM today.
- Small Craft Advisory — Chesapeake Bay zones (north of Pooles Island through Sandy Point/North Beach corridor) — until 8:30 AM today; advisory conditions expected to extend through 11 PM Sunday.
Best Window to be Out: Monday night into Tuesday — light E to NW winds around 5 kt, seas 1 ft or less on the Bay, 2-3 ft offshore. That's your fishing and cruising window.
Worst Window: Sunday afternoon through Sunday night — wind, seas, and thunderstorm risk all peak together.
Bottom Line: Today is workable on the ocean once the morning SCA expires on the Bay, but Sunday is a stay-in day — wait for Monday night.
