Annual Water Temperature Trend

Waterford, Connecticut, sits on the northern shore of Long Island Sound and features a mix of rocky shoreline, sandy coves, and sheltered bays that reflect its coastal New England character. Because it is part of an estuarine environment, water temperatures vary considerably through the year. In winter months the surface water commonly falls to about 0–5 °C, while spring sees a gradual rise into the roughly 5–12 °C range as air temperatures warm. By summer the Sound is at its warmest, typically registering around 18–24 °C with peak readings in July and August; early autumn remains pleasant for swimming, often 15–20 °C, before cooling again into late fall toward 10–12 °C and lower as winter approaches. Local weather patterns, tides, and coastal currents can cause short-term variations, so actual conditions may differ from averages.
