*** 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
Carter Lake, an oxbow lake adjacent to Council Bluffs in Iowa, experiences marked seasonal shifts in water temperature. In winter the surface can hover around freezing to the low 40s °F (about 0–4 °C), often forming ice in cold spells. Spring brings a steady rise, with typical temperatures from the mid‑40s to mid‑60s °F (7–18 °C) as ambient air warms. By summer the lake commonly reaches the warmest conditions, often ranging from the low 70s to low 80s °F (21–28 °C) on sunny days, though localized variations occur with depth, wind and shading. Fall sees a cooling trend back into roughly the 50s–60s °F (10–20 °C) before winter cold returns. These figures are approximate averages and can vary year to year and across different parts of the lake.
Swimming is allowed in designated recreation areas around Carter Lake, notably the municipal park beach, because those sites are managed for public use and marked for safety. However, swimmers should observe posted rules, as lifeguard coverage, launch zones, boat traffic, water clarity and occasional algal blooms can affect safety and water quality. Seasonal advisories or temporary closures may be issued by local authorities, so checking current notices before entering the water is recommended.
