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
In Des Moines, Iowa, the Des Moines River runs through the city, offering scenic views and opportunities for water-based recreation. However, swimming in the river itself is not widely recommended due to various factors such as strong currents, potential pollution, and the depth of the river. The water temperature in the river fluctuates throughout the year, with cooler temperatures of around 40°F to 50°F (4°C to 10°C) during the winter months. In the summer, the temperature rises to more comfortable levels of around 70°F to 80°F (21°C to 27°C), which could be refreshing but still doesn't make it ideal for safe swimming, particularly due to the river's flow and water quality concerns.
The Des Moines River is known for its strong currents, especially during the spring melt or after heavy rains, which can make swimming dangerous. Additionally, while some local residents may occasionally wade or cool off in the shallower areas, the water quality can be inconsistent. Stormwater runoff and agricultural pollution are common issues, which may impact water safety, especially in terms of bacteria levels, making it unwise to swim in the river without taking proper precautions.
Despite the challenges posed by the river itself, Des Moines offers other water-based activities in designated areas. There are a number of parks and recreational spots with managed ponds, lakes, and swimming areas that provide safe environments for swimming and enjoying the water. For those who enjoy water sports, the river does allow for boating, kayaking, and fishing, but these activities should be done with awareness of the river's natural dynamics and safety considerations.
