As New Jersey moves through the first full week of September, residents can enjoy a generally calm and comfortable weather pattern, punctuated by a brief coastal disturbance midweek. The upper-level atmospheric pattern has been more meridional than zonal at times, yet no extreme or anomalous geopotential heights are expected across the state over the next seven days. This sets the stage for a stretch of mostly enjoyable conditions with mild temperatures, low humidity, and seasonal breezes.
A minor wrinkle is expected around Wednesday as a weak coastal low passes just offshore. Current forecasts suggest this system will begin influencing conditions on Tuesday with choppier surf and increased rip currents along the Jersey Shore. By Wednesday, clouds and scattered showers could reach portions of the coastline and possibly extend inland toward the Delaware River. While the precise extent of the rainfall remains uncertain, impacts are expected to be light and typical of these offshore storms, with the heaviest rain and strongest winds staying offshore near the storm’s center. By Wednesday night, skies should clear, and the state will quickly return to a cool, dry, and pleasant pattern that will persist through the end of the week and into the weekend.
Detailed Daily Forecast:
Monday, Sept. 8: Expect mostly sunny skies with high temperatures in the low to mid-70s across New Jersey. Light northerly winds will prevail inland, while breezes from the northeast along the coast may produce elevated surf and rip currents. Overnight lows will range from 45 to 50 degrees inland, with coastal areas remaining slightly warmer in the 50s to 55 degrees.
Tuesday, Sept. 9: Daytime highs will climb into the mid-70s. Skies remain mostly sunny, though a few coastal clouds may develop as the offshore storm approaches. Humidity stays low, keeping conditions comfortable. Northeast winds may gust along the immediate coastline, reinforcing concerns for rough surf and rip currents. Overnight temperatures will vary from 50 to 65 degrees, cooler inland and warmer along the coast, with scattered showers possible overnight.
Wednesday, Sept. 10: A mix of clouds and scattered showers will accompany the offshore system, keeping highs near or just above 70 degrees. Winds from the north and northeast will remain light to breezy. By evening, conditions should improve statewide, with overnight lows ranging from 45 to 60 degrees depending on location.
Thursday, Sept. 11: Highs rebound to the mid-to-upper 70s with dry and comfortable conditions. Some interior areas in central and southern New Jersey may briefly exceed 80 degrees. Expect a blend of sun and clouds, light northerly winds, and overnight lows between 50 and 60 degrees.
Friday, Sept. 12: A mostly sunny day with highs in the mid-to-upper 70s continues the pleasant stretch. Light east-to-northeast winds prevail, with overnight temperatures again between 50 and 60 degrees.
Weekend Outlook, Sept. 13–14: Early indications point to a weekend of clear skies and low humidity. Daytime highs will remain in the 70s, while nighttime lows dip into the 50s, creating ideal conditions for outdoor activities, beach trips, or early fall hikes.
With the Atlantic tropical season quieting down—Invest 91L has dissipated before reaching the Lesser Antilles—New Jersey is enjoying a non-active period in the tropics. Residents and visitors can look forward to a week of mild, picture-perfect weather, interrupted only by minor coastal surf concerns midweek.
