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 Two, like many small prairie lakes in South Dakota, experiences a wide range of surface water temperatures through the year. In spring the water commonly warms from near-freezing after ice-out to roughly 45–65°F (7–18°C) as air temperatures rise. Peak summer conditions often produce the warmest readings, with surface temperatures typically between about 70–82°F (21–28°C) on warm sunny days and occasionally higher in shallow areas during heat waves. By early autumn the lake cools back toward 50–65°F (10–18°C), and in winter it usually reaches around freezing at 32°F (0°C) where ice forms, with colder air able to maintain ice cover until thaw.
Swimming opportunities depend less on a fixed prohibition and more on local access, water quality and safety conditions. In warm months people can and do swim when surface temperatures are comfortable, but there are often no formal lifeguards, maintained beaches or facilities at small prairie lakes, and ownership or county rules may restrict contact recreation. Algal blooms, vegetation, soft muddy bottoms and fluctuating water levels can make swimming inadvisable at times, so visitors should check local signage, water clarity and official guidance before entering the water and always consider personal safety and hypothermia risk even on warm days.
