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
Saint Andrews, a coastal town in southwestern New Brunswick on the edge of the Bay of Fundy and Passamaquoddy Bay, is defined by rocky headlands, sheltered coves and wide tidal fluctuations. Water temperatures here change markedly with the seasons and local conditions: winter sea surface temperatures commonly hover around 0–2 °C, spring sees a gradual rise into roughly 2–8 °C, summer brings the warmest conditions typically in the 12–18 °C range, and autumn waters cool again to about 6–12 °C. Temperatures also vary with depth, wind and exposure; shallow, sun-warmed coves can be a few degrees warmer than the open bay, while strong tidal exchange in channels keeps some areas distinctly colder.

Swimming Conditions
Swimming and beach holidays in Saint Andrews suit visitors who enjoy cool, coastal waters and a mix of sandy spots and rocky shorelines rather than long, warm beach seasons. The warmest months offer the most conventional swimming, though water remains brisk compared with more southerly resorts and many swimmers use wetsuits or keep sessions brief. Tidal rhythms dramatically affect where and when you can swim or beach-comb—large tides expose flats and change currents—so choosing sheltered coves on calm days is common. Facilities and lifeguard coverage are limited compared with major resort beaches, but the area is popular for paddling, shoreline walks and family beach outings during summer, with scenic views and easy access to adjacent coastal activities.
