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
Cold Springs Reservoir in Oregon typically has cool water year-round, with surface temperatures that vary by season. In spring (April–May) surface readings commonly range from about 40–55°F (4–13°C) as runoff and cooler air keep the lake brisk. Summer highs (June–August) often bring the warmest surface water, roughly 60–70°F (15–21°C) on sunny days, though deeper water stays noticeably colder. In fall (September–October) temperatures generally fall back to about 45–60°F (7–16°C). Winter conditions can drop the reservoir near freezing, roughly 33–42°F (0–6°C), especially where ice forms or cold inflows dominate.
Swimming at Cold Springs Reservoir is generally allowed because the site is used for multiple recreational purposes, including boating and angling, and is managed to permit public access. Nonetheless, some shorelines or access points can be posted or temporarily closed for irrigation operations, safety around boat traffic, or hazardous banks and submerged structures. The water’s cool temperature year-round increases the risk of cold shock and hypothermia, so swimmers should be cautious, avoid extended immersion outside peak summer warmth, consider a wetsuit in cooler months, and heed local signs and guidance before entering the water.
