Water Temperature: Daily Trends, Historical Records, and Forecast
✅ As of today, the minimum water temperature ranges from 79°F (26°C) to 82°F (28°C). This is very warm water, allowing for extended stays without any discomfort. Swimming in these conditions will be particularly enjoyable, making it the ideal temperature range for those who want to relax in the sea. Additionally, water in this temperature range is suitable for children and elderly people, as it is comfortable for prolonged stays. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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
Aurora Reservoir’s surface water temperatures vary widely through the year because of Colorado’s seasonal swings and the reservoir’s depth. In winter the surface often sits near freezing, roughly 32–40°F (0–4°C). Spring warming raises surface readings into the 40s and 50s Fahrenheit, about 4–16°C, though cool spells can persist. Peak summer surface temperatures commonly reach the mid-60s to mid-70s F, approximately 18–24°C, especially on sunny, calm days. In early fall the surface typically cools back into the 50s–60s F (10–18°C). Deeper water remains colder than the surface year-round, so suit choice and exposure time are important considerations.
Swimming at Aurora Reservoir is permitted but generally confined to designated swim areas during the staffed swim season for safety and water‑quality monitoring. Those areas are chosen to separate swimmers from boating and to allow lifeguard supervision and routine testing; outside posted swim times or outside the designated zone, swimming is discouraged because colder temperatures, changing weather, boat traffic, and the risk of hypothermia or winter ice make open‑water swimming hazardous. Visitors should check current local guidance and conditions before entering the water.
