🌊 US Weather Warriors MarineCast — Sunday, July 26, 2026

Light winds, low waves, and no radar activity near Delmarva make Sunday the workable day before southerly winds, showers, and thunderstorms build toward Tuesday.

Today on the Water: Primarily dry conditions are expected today, and radar is quiescent with no active cells within 50 miles of Delmarva. The marine setup turns less favorable Monday into Tuesday as winds shift southerly and increase. Tuesday brings the higher-impact stretch, with showers and thunderstorms in the forecast and the roughest conditions Tuesday night.

Atlantic Coastal Waters (Lewes → southern VA coast): Today-specific wind and sea data are limited for this zone. The roughest coastal conditions arrive Tuesday night: southwest winds 15 to 20 kt with gusts up to 25 kt and seas 3 to 4 ft, occasionally to 6 ft. Showers and thunderstorms are likely Tuesday evening, followed by showers and a chance of thunderstorms after midnight.

Delaware Bay: Northeast winds around 5 kt become southeast this afternoon, with seas 1 foot or less. This is a manageable Bay day for smaller boats, with the lightest conditions holding today. Conditions deteriorate Tuesday night as south winds reach 15 to 20 kt with gusts up to 25 kt before becoming southwest after midnight.

Chesapeake Bay & Delmarva-facing Waters: North winds near 5 kt become east late, with waves around 1 foot. Light winds and primarily dry conditions support a favorable daytime run. Southerly winds build Tuesday, increasing from 10 to 15 kt to 15 to 20 kt during the afternoon, with gusts up to 25 kt and showers or thunderstorms possible.

Wind & Seas Outlook: The peak wind period is Tuesday into Tuesday night, especially along the Atlantic coast and Delaware Bay. Highest coastal seas are Tuesday night, reaching 3 to 4 ft and occasionally 6 ft offshore.

Marine Alerts: No active marine alerts.

Best Window to be Out: Today through early afternoon, before the late east wind on Chesapeake Bay and ahead of the stronger southerly pattern early next week.

Worst Window: Tuesday night, especially Atlantic coastal waters, with 15 to 20 kt southwest winds, 25 kt gusts, rough seas, and thunderstorms.

Bottom Line: Launch today if your plan fits light-wind conditions, but plan around a distinctly rougher and stormier Tuesday into Tuesday night.
