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
Buzzards Bay is a semi-enclosed inlet on the western side of Cape Cod in Massachusetts, characterized by a mix of shallow coves, tidal estuaries and deeper channels. Water temperatures vary seasonally and by location: in winter surface temperatures commonly fall to about 0–4°C, spring brings a gradual rise into the 4–12°C range, and by midsummer the bay often warms to roughly 16–24°C in sheltered shallows and slightly cooler offshore. Autumn sees a steady cooling, typically between 10 and 16°C. Local variations are notable—shallow, sun-warmed coves and tidal flats can be several degrees warmer than nearby channels, while strong tides and river inflows can produce colder pockets even in summer.
