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
Westbrook sits on the Connecticut shoreline of Long Island Sound, where coastal temperatures follow a distinct seasonal rhythm. Winter months typically bring water temperatures down to about 0–5°C, while spring sees a gradual rise into the 4–12°C range as shallows warm first. By summer, surface waters commonly reach between 18 and 24°C, with the warmest readings in July and August; autumn then cools the Sound back toward roughly 10–18°C. Tidal action, wind and weather can cause day-to-day variations, and shallow protected coves warm more quickly than exposed stretches. These temperature ranges reflect surface conditions most relevant to casual swimmers, whereas deeper or shaded areas stay cooler.
