🌊 US Weather Warriors MarineCast — Friday, August 14, 2026
Light winds and generally manageable water today give way to a much rougher southerly push Sunday, with Small Craft Advisory-type conditions possible later in the period.
Today on the Water:
Light and variable winds are expected across the waters today, with the steadiest favorable conditions on Chesapeake Bay.
Radar is quiet: no active cells within 50 nm of Delmarva or the Bay corridors. Showers and thunderstorms remain in the forecast at times later in the period.
The real deterioration arrives Sunday as southerly winds build.
Atlantic Coastal Waters (Lewes → southern VA coast):
Today-specific wind and sea details are limited for this zone; the broader marine forecast calls for light and variable winds today.
Sunday night turns rougher with southwest winds 15 to 20 kt, gusts to 25 kt, and seas 3 to 4 ft, occasionally to 6 ft. Showers are likely.
Delaware Bay:
Today-specific Bay details are limited, but lighter conditions hold through tonight: east winds around 5 kt and seas 1 foot or less.
Sunday afternoon, south winds increase from 5 to 10 kt to 15 to 20 kt with gusts up to 30 kt; seas build to 2 to 3 ft with a chance of showers.
Chesapeake Bay & Delmarva-facing Waters:
Northeast winds near 5 kt and flat waves make Today the best local water window.
Sunday night brings south winds 15 to 20 kt with gusts up to 25 kt, plus likely showers and a chance of thunderstorms.
Wind & Seas Outlook:
The peak wind period is Sunday afternoon in Delaware Bay, with gusts up to 30 kt.
The roughest coastal sea period is Sunday night, when Atlantic seas reach 3 to 4 ft and may occasionally hit 6 ft.
Marine Alerts: No active marine alerts.
Best Window to be Out: Today, especially on Chesapeake Bay and sheltered Delmarva-facing waters, with northeast winds near 5 kt and flat waves.
Worst Window: Sunday afternoon through Sunday night, as southerly winds strengthen, seas build, and showers or thunderstorms develop.
Bottom Line: Launchable conditions hold today, but plan around a significant Sunday deterioration—particularly offshore and in Delaware Bay.
