Live hydrological sensor reading for Lake Cushman.
Excellent for boating (97/100), from 4 available inputs. Supporting this: Wind 5 mph from the west-southwest. Gusts to 7 mph. 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 (78/100), from 6 available inputs. Supporting this: Wind 5 mph from the west-southwest. 1% chance of precipitation. Not available from a verified source for this lake: pressure trend. Confidence is moderate (80%) because some inputs are unavailable or older than ideal.
Fair for kayaking (71/100), from 5 available inputs. Supporting this: Wind 5 mph from the west-southwest. Gusts to 7 mph. Water temperature is 48°F (combined air+water: 100°F). Cold shock hazard: sudden immersion below 55°F poses serious risk. Confidence is high (90%).
Very Poor / Avoid for swimming (21/100), from 5 available inputs. Supporting this: No active official alerts for this lake. 1% chance of precipitation. Working against it: Measured water temperature 48°F from a representative gauge 8.2 mi away. Provisional data. Immersion shock hazard: water below 55°F poses severe cold shock and rapid hypothermia risk. Air temperature 52°F. Water temperature is 48°F (below 55°F). Severe cold shock and hypothermia hazard upon immersion. Confidence is high (85%).

Mirror-like to gentle rippled water. Optimal conditions for paddleboarding, kayaking, swimming, and beginner water skiing or wakeboarding.
Pleasant breeze with small wavelets. Great for sailing, pleasure cruising, pontoon boats, and trolling for trout and bass.
Moderate waves with whitecaps likely. Requires skilled boat handling; kayaks, canoes, and stand-up paddleboards should stay close to sheltered bays.
Steep waves, cold spray, and hazardous open water. Avoid small craft voyages. Always check official National Weather Service lake wind advisories.

Lake Cushman currently reports 55°F with wind velocity near 4 mph from the SE. 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 Lake Cushman 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 SEW) high-resolution numerical point-forecast API. LakeRadar uses the official gridpoint for Lake Cushman without artificial smoothing or third-party estimates.
