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 Trend
Milford, Connecticut sits on the northern shore of Long Island Sound, where coastal waters are influenced by tides, river outflow and seasonal air temperatures. Surface water temperatures close to Milford typically range from near freezing in the coldest months to comfortably warm in midsummer. In winter, January and February averages can fall to about 0–4 °C, while spring sees a steady rise with March through May commonly between 5–12 °C. By July and August the Sound often reaches its warmest, roughly 18–24 °C in sheltered nearshore areas, and early autumn can still hold water around 12–20 °C depending on weather patterns.
