Annual Water Temperature Trend

Weekapaug, located on the southern Rhode Island coast, sits where the Atlantic Ocean meets a series of salt ponds and barrier beaches, producing a variety of local water conditions. Seasonal sea temperatures follow the regional New England pattern: winter waters typically range from about 2°C to 6°C, spring sees a steady rise into the single and low double digits roughly 6°C to 15°C, and summer brings the warmest conditions, commonly between 18°C and 24°C with shallow ponds occasionally reaching the mid-20s °C on hot, calm days. Autumn cooling is gradual, with surface temperatures often falling from around 18°C in early fall to 10°C–12°C by late season. Local factors such as shallow pond depth, tides, wind direction and recent weather can shift these averages noticeably from day to day.
