Marine Forecast Discussion

Forecast: Strong ridging in the NE US and mid-Atlantic this weekend will result in a heatwave that will likely be the hottest of the summer thus far. Air temperatures in the low to mid 90s on Friday combined with the expected high dewpoints will lead to heat index values between 105-110° and over the weekend with air temps in the upper 90s, 110-115° peak heat indices can be expected. With water temperatures slightly above average and no precipitation expected, it will be a good beach weekend. A cold front moves through on Monday with numerous scattered showers and thunderstorms that will continue overnight, and end as showers as the front clears early Tuesday. Skies become partly cloudy later Tuesday as the front passes with lowering humidity, then remains partly cloudy Wednesday with low humidity expected.

Tropical concerns:  None

Marine:  Latest observations show seas are currently around 3-4 feet with a southerly swell, and a dominant period of 5-7 seconds. Forecast is for a wave heights to maintain on Friday, then take a slight step back on Sunday to 2-3 feet. A cold front will approach on Sunday, but precipitation is not expected to make it here until Monday, but wave heights will increase in advance of it Sunday to 3-4 feet, and maintain those levels until the front completely clears on Tuesday, then lowering on Wednesday. Any thunderstorm presence, even if isolated, can provide rough seas, and you should consult and heed localized statements from the National Weather Service with regard to coastal marine advisories. Ocean water temps will continue to run slightly above average through next week.
