*** 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
Many Point Lake in north-central Minnesota shows pronounced seasonal shifts in water temperature. In spring (roughly May–June) surface temperatures typically run about 40–60°F (4–16°C) as ice melts and the water mixes; in summer (late June–August) the surface commonly warms to about 68–78°F (20–26°C), with occasional warm spells pushing into the low 80s°F (~27–28°C) on hot days. In early fall (September–October) temperatures decline to roughly 50–65°F (10–18°C) as cooling and turnover occur, while winter months (December–March) usually bring ice cover and water beneath the ice near 32–39°F (0–4°C). Deeper layers remain colder year-round and lakes can stratify, so temperatures below the thermocline are substantially lower than surface readings.
Swimming is generally allowed during the open-water season and many visitors swim when surface temperatures are in the comfortable summer range, but access can be governed by local rules, posted advisories, or resort policies. Water quality, underwater hazards, weather and lack of lifeguards can affect safety, and colder spring or fall water—below about 60°F (15°C)—increases hypothermia risk and shortens safe swim time. In winter the ice prevents normal swimming except at organized, supervised ice-swim events with proper safety measures. It’s best to heed local signage and guidance about beach closures, water-quality notices and safety conditions.
