*** 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
Fargo, located in eastern North Dakota along the Red River of the North, experiences a continental climate with warm summers and cold winters, which strongly affects the river’s water temperature. In early spring, as snow and ice melt, the Red River remains very cold, averaging around 37–43°F (3–6°C). By late May and June, surface temperatures rise to about 50–59°F (10–15°C). During midsummer, from July through August, the river near Fargo reaches its warmest levels, with surface temperatures typically between 64–72°F (18–22°C) depending on rainfall and flow rate. As autumn approaches, cooling air and shorter days bring temperatures back down below 55°F (13°C) by late September.
Swimming in the Red River of the North at Fargo is not recommended, even though the water can feel mild in midsummer. The river’s slow current may appear calm, but it conceals sudden depth changes, strong undercurrents, and murky visibility. Local authorities discourage swimming due to safety risks and variable water quality. While wading along the shore or taking part in boating and kayaking are common, most residents choose nearby lakes in Minnesota or North Dakota for safe, clear-water swimming. The Red River remains best suited for scenic enjoyment and recreation on the water rather than in it.
