Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.
Water temperature data for this location is gathered from various sources, including buoys and satellite sea and ocean surface maps provided by the NOAA agency. We also incorporate data from local authorities in each specific location worldwide to ensure more accurate temperature readings.
Annual Water Temperature Overview by Month
Monthly Water Temp Ranges
Annual Water Temperature Trend
Brooklyn sits on New York City’s western Long Island coastline, facing the Upper New York Bay, Jamaica Bay, and the Atlantic Ocean. Its waters are influenced by tidal currents, urban runoff, and seasonal air temperatures, so surface temperatures vary significantly over the year. In winter months the coastal surface often falls to near freezing, commonly around 0–5 °C. Spring sees a steady rise, with March to May typically ranging from about 4–15 °C. Summer brings the warmest conditions, with June to August surface temperatures most often between 18 and 25 °C and occasional peaks above that during heatwaves. As autumn arrives, temperatures decline again, generally moving from roughly 20 °C in early September down to 10–15 °C by November. These figures are approximate and can change with weather patterns, tides, and local sheltered versus exposed locations.

Swimming Conditions
Swimming and beach recreation in Brooklyn center on a few well-known shorelines and managed sites where lifeguards and facilities are provided during the warmer months. Coney Island and Brighton Beach are the primary public beach destinations with designated swimming areas that are busiest when water temperatures are most comfortable, typically mid-June through early September when surface waters are in the high teens to mid-twenties °C. Manhattan Beach also offers a more residential option with lifeguarded areas. Water quality and currents vary, so authorities post advisories at times, and some parts of Jamaica Bay are better suited to kayaking, paddleboarding, or nature observation than open-water swimming. For cooler-season swimming, Brooklyn residents often use indoor pools and managed aquatic centers rather than the open coastal waters.
