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
Shediac sits on the protected waters of the Northumberland Strait in New Brunswick and is widely noted for having some of the warmest saltwater temperatures on Canada’s Atlantic coast. Because the area is shallow and sheltered, the sea here warms more quickly than open-ocean locations. Typical seasonal water temperatures range from near freezing in winter, around 0 to 3 °C, to early spring values of roughly 4 to 12 °C. By June the water commonly rises into the low to mid teens, and in the peak of summer — July and August — surface temperatures frequently reach about 20 to 24 °C, occasionally a little higher in very calm, sunny stretches. As autumn sets in, temperatures usually fall back through the mid teens and into the single digits by October and November.
