Chilly Waters: Why New Jersey’s Ocean Temperatures Are Cool in June
SEASIDE HEIGHTS, NJ — As New Jersey beachgoers dip their toes into the ocean this June, they might find the water surprisingly chilly. Recent measurements show average ocean temperatures along the coast from Sandy Hook to Cape May at about 65 degrees this week.
This cool temperature is typical for early summer in New Jersey. Historical data reveals that the average ocean temperature near Seaside Heights in June is approximately 66.2°F. The lowest recorded at this time of year was 57°F, while the peak has reached up to 74.7°F. These figures suggest that the current temperature is well within the expected range for this season.
Ocean temperatures in the Atlantic near New Jersey are influenced by several natural factors. The cold Labrador Current, which flows down from the north, plays a significant role in keeping the coastal waters cool. Additionally, winds and weather patterns can greatly affect sea temperatures, with prolonged periods of northerly winds contributing to cooler surface waters.
It is also notable that ocean temperatures typically lag behind air temperatures in heating up. Water has a higher heat capacity than air, meaning it takes a longer time to warm up and cool down. Therefore, even as air temperatures rise with the onset of summer, ocean temperatures often take longer to increase.
Despite the cooler waters, the swimming season in Seaside Heights still extends from June to September. During these months, water temperatures do not typically fall below 68°F, making it suitable for comfortable swimming.
For those planning a beach day in New Jersey this early summer, it might be wise to prepare for cooler ocean dips, a common characteristic of the season along the state’s picturesque coastline.
