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
Duxbury, Massachusetts, sits on the South Shore of Massachusetts Bay and includes a mix of protected bay waters and more exposed barrier beach facing the open ocean. Water temperatures in the area vary considerably through the year because of shallow bay waters warming faster in summer and cold offshore currents in winter. Typical winter sea surface temperatures hover around 0–4 °C, with spring slowly rising from about 4–12 °C by late May. Summer brings the warmest conditions, often between 17–22 °C in July and August in the more sheltered parts of the bay, while the exposed ocean side can remain a few degrees cooler. Early autumn commonly keeps water in the 15–20 °C range before cooling toward 5–10 °C by late fall.

Swimming Conditions
Swimming and beach holidays in Duxbury reflect those seasonal patterns. The sheltered bay and stretches of barrier beach offer shallow, generally calmer waters that are popular with families during the warmest months, and staffed swimming areas are typically available on a seasonal basis. The open-ocean side provides surf and broader vistas but can have stronger currents and colder temperatures even in summer, so swimmers should be cautious and heed posted warnings or lifeguard advice. Water quality is monitored locally and can change after heavy rain, and many visitors find the most pleasant swimming conditions from mid-July through September; in the shoulder seasons a wetsuit makes paddling and swimming more comfortable.
