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
Staten Island sits at the southern edge of New York City, bordered by Upper New York Bay, Raritan Bay and the Lower New York Bay, so its waters reflect a coastal temperate pattern with strong seasonal swings. In winter months the sea can be very cold, often around 0–4°C in January and February as coastal waters cool and mixing increases. Spring brings gradual warming: by April temperatures commonly reach 6–13°C and by May 12–18°C. Summer is when the water is most comfortable for swimming, typically peaking in July and August between about 21–26°C, with early June and September often still pleasant in the high teens to low twenties Celsius. In autumn the surface temperature declines again, falling to roughly 10–18°C in October and down toward single digits by late November and December. Local tides, currents and recent weather can cause short-term variations from these typical ranges.

Swimming Conditions
Swimming and beach recreation on Staten Island are largely summer activities centered on the borough’s public shoreline and parks. Lifeguarded beaches operate mainly during the warmer months, and when surface temperatures are in the low to mid‑20s°C they attract swimmers, sunbathers and families seeking a quick seaside escape without leaving the city. Facilities such as promenades, picnic areas and seasonal concessions support day visits, while nearby marshes and rocks offer opportunities for tidepooling and shoreline walks. Water quality has improved over decades but can be affected after heavy rain, so swimmers often check local advisories; areas exposed to open currents or boat traffic can be cooler and sometimes choppier than more sheltered bays, so choosing a supervised beach during the high season is advisable for a beach holiday on Staten Island.
