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
Montauk, located at the eastern tip of Long Island, sits where the Atlantic Ocean meets Block Island Sound, creating a varied coastal environment that influences water temperatures. Seasonal sea surface temperatures typically range from about 0–6°C in winter (December–February), rise to roughly 5–15°C during spring (March–May), warm further to about 15–24°C in summer (June–August) with the warmest readings usually in July and August, and cool again through autumn to approximately 8–18°C (September–November), with September often retaining milder water for a while before steady decline. Local conditions such as offshore currents, upwelling, tides and wind can produce notable day-to-day variation, and sheltered bays often run slightly warmer than exposed ocean beaches.
