Southern NJ Beaches Forecast

Beach forecasts are updated weekly on Thursdays prior to an upcoming weekend throughout the summer months, from Memorial Day through Labor Day (seasonal)

Marine Forecast Discussion

Forecast: The forecast period begins with a mostly sunny day with near average temperatures and lower humidity, as the wind flow will be out of the NW in the wake of Thursday evening's cold front. Both temperatures and humidity will begin to increase over the weekend as upper air ridging moves in from the SW, and will set up over the region early in the new week leading to hot conditions and dry conditions through midweek.

Tropical concerns: No tropical cyclone threats are forecast in the coming week. 

Marine: Seas currently feature approximately 3-4 ft. wave heights with a southeasterly swell, and a dominant period of 4-7 seconds. Wave heights will start the forecast period at 3-4 ft. levels Friday in the immediate wake of a cold front that moves through the prior Thursday night, then will decrease Friday night onward and remain and normal 2-3 ft. wave heights throughout the upcoming week. Thunderstorms can provide localized rough boat and beach conditions higher than wave heights indicated, and you should monitor statements issued by the National Weather Service forecast office in Mount Holly, NJ for the latest marine advisories. At present time, no thunderstorm activity is expected within this forecast period, and any storm activity with the aforementioned cold front will likely move offshore Thursday evening. Ocean water temperatures will continue to run near to slightly below seasonal average for this upcoming week in the upper 60s.
