*** Forecast - Our water temperature forecast
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.

Location & Local Information
Moncton, located in southeastern New Brunswick along the Petitcodiac River, experiences significant seasonal variation in its inland water temperatures due to the province’s humid continental climate. The Petitcodiac River itself is tidal and influenced by the famous tidal bore, which keeps the water generally cool and muddy, with limited swimming suitability. In early spring, river temperatures average around 39–45°F (4–7°C). By late May and June, they may rise to about 52–59°F (11–15°C). During midsummer, from July through August, calmer sections of local rivers and smaller nearby lakes can warm to 66–72°F (19–22°C), particularly in shallow areas away from strong currents. By late September, temperatures gradually fall below 59°F (15°C) as autumn sets in.
Swimming in the Petitcodiac River near Moncton is not recommended due to strong tides, turbidity, and variable water quality. However, nearby freshwater lakes and ponds around the Greater Moncton area provide safer and more comfortable options for summer swimming. These smaller bodies of water warm up quickly during the summer months and are often used for recreation, kayaking, and paddleboarding. The best time for swimming in the Moncton area is from late June through early September, when air and water temperatures are most favorable for outdoor water activities.
