*** 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
Greenwood Lake’s surface water temperature varies with the seasons and can change with weather and depth. In spring (April–May) surface readings are commonly in the mid‑40s to around 60°F (7–16°C) as the lake warms. By summer (June–August) temperatures usually peak, often ranging from the upper 60s to upper 70s Fahrenheit (about 20–26°C), with the warmest values in late July and August. Early fall (September–October) typically sees a gradual decline into the 60s°F (15–21°C) as cooling sets in. In late fall and winter the lake can fall to near freezing, commonly 32–45°F (0–7°C) on the surface in cold spells, and ice formation is possible in sustained cold periods.
Swimming in Greenwood Lake is commonly done in the warmer months where public and private beaches and launch areas permit access, but availability and supervision are seasonal. Municipal beaches, where open, often post rules and may provide lifeguards during peak summer hours; many shoreline spots have no lifeguards and boating activity can create hazards. Cold water and sudden temperature changes increase the risk of shock and hypothermia, so swimming is generally safest when surface temperatures are in the comfortable summer range and in areas designated for swimming. Ice and very cold conditions make swimming unsafe and are typically prohibited.
