Live hydrological sensor reading for Loon Lake.
Good for boating (83/100), from 4 available inputs. Supporting this: Wind 9 mph from the west-southwest. No active official alerts for this lake. Not available from a verified source for this lake: visibility and conditions, verified water access. Confidence is moderate (84%) because some inputs are unavailable or older than ideal.
Good for fishing (77/100), from 6 available inputs. Supporting this: Wind 9 mph from the west-southwest. 0% chance of precipitation. Not available from a verified source for this lake: pressure trend. Confidence is moderate (72%) because some inputs are unavailable or older than ideal.
Fair for kayaking (58/100), from 5 available inputs. Supporting this: Wind 9 mph from the west-southwest. No active official alerts for this lake. Water temperature is 47°F (combined air+water: 118°F). Cold shock hazard: sudden immersion below 55°F poses serious risk. Confidence is high (90%).
Very Poor / Avoid for swimming (27/100), from 5 available inputs. Supporting this: No active official alerts for this lake. 0% chance of precipitation. Working against it: Measured water temperature 47°F from a representative gauge 14.1 mi away. Provisional data. Immersion shock hazard: water below 55°F poses severe cold shock and rapid hypothermia risk. Water temperature is 47°F (below 55°F). Severe cold shock and hypothermia hazard upon immersion. Confidence is moderate (75%) because some inputs are unavailable or older than ideal.

Loon Lake currently reports 69°F with wind velocity near 15 mph from the SW. Atmospheric forecasts and 24-hour hour-by-hour wind timelines are updated hourly from the National Weather Service gridpoint matching the lake's coordinates.
At Loon Lake and surrounding mountain valleys, diurnal heating of the surrounding terrain causes strong thermal pressure differentials known locally as afternoon breezes (such as the Washoe Zephyr at Lake Tahoe). Wind speeds typically peak between 1:00 PM and 5:00 PM before calming near sunset.
For stand-up paddleboarding (SUP), canoeing, and light kayaks, winds under 7 mph (light breeze) offer the safest, glassiest surface conditions. Between 8–14 mph, small wavelets develop, suitable for sailboats and powerboats. Winds exceeding 15 mph create steep whitecaps and rapid drift; winds over 21 mph warrant small craft warnings.
All weather and wind telemetry is fetched directly from the National Weather Service (NOAA - WFO STO) high-resolution numerical point-forecast API. LakeRadar uses the official gridpoint for Loon Lake without artificial smoothing or third-party estimates.
