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
South Fork Reservoir in Nevada typically has cool to cold water for much of the year because of its elevation and seasonally variable inflows. Surface temperatures in spring and early summer often sit in the mid-30s to mid-50s °F (about 2–13 °C) as snowmelt and cool runoff dominate. By mid- to late summer the surface can warm into the mid-60s to mid-70s °F (roughly 18–24 °C) on warm, sunny days, with the warmest readings usually occurring in July and August. As autumn returns and air temperatures fall, surface values drop back into the 40s and 50s °F (around 5–15 °C), and in winter the water is frequently near freezing, typically in the low 30s to low 40s °F (0–5 °C) where open water persists.
Swimming at South Fork Reservoir is generally permitted as a recreational activity at many reservoirs in Nevada, but access and specific rules can vary by land manager or season. The main reasons people are allowed to swim are that reservoirs are used for public recreation and there is no widespread prohibition in many areas; however, swimmers should be cautious because cold water can cause shock and rapid loss of body heat, there may be sudden drop-offs, boat traffic, and occasional water-quality advisories. Visitors should check local signage or contact the managing agency before swimming and take standard safety precautions.
