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
Dry Lake Number One is a typical shallow prairie lake in South Dakota, so its surface water temperatures change a lot through the year. In spring the lake is cold, often ranging from about 40–60°F (4–15°C) as snowmelt and cool rains freshen the water. Summer is when the surface warms most: typical summer surface temperatures are roughly 60–80°F (16–27°C), and on hot, calm afternoons shallow bays can reach the mid‑80s°F (around 29°C). In fall temperatures fall back into the 40–60°F (4–15°C) band as air cools, and in winter the lake commonly freezes with water at or below 32°F (0°C) under ice cover.
Swimming opportunities depend less on a uniform rule and more on local conditions and regulations. Recreational swimming is physically possible during the warmer months when surface temperatures are comfortable, but whether you should swim depends on access, signage, water quality (turbidity and algal blooms can occur in shallow lakes), and safety resources such as lifeguards. Many small prairie lakes have no formal swim facilities or monitoring, so visitors are advised to check with county or state authorities for advisories, avoid areas with visible algae or debris, and consider that shallow, warm water can heat quickly but may also harbor hazards.
