Annual Water Temperature Trend

Sandy Hook is a long, sandy barrier spit on the Jersey Shore, forming the northern tip of the barrier islands in New Jersey and separating the Atlantic Ocean from the calmer waters of Raritan Bay. It is part of a national recreation area and offers a mix of open-ocean and bay environments, which influence water temperatures. Seasonal sea-surface temperatures typically range from about 2–6 °C in the coldest winter months up to roughly 18–24 °C in midsummer. Spring sees a steady rise, often between 6–15 °C, while early autumn commonly holds temperatures in the mid-teens to low twenties °C as the ocean slowly cools. Local conditions can shift with weather patterns, tides and upwelling, so short-term temperatures may differ from seasonal averages.
