Live hydrological sensor reading for Crater Lake.
Fair for boating (74/100), from 4 available inputs. Supporting this: No active official alerts for this lake. 1% chance of precipitation. 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.
Fair for fishing (61/100), from 6 available inputs. Supporting this: 1% chance of precipitation. Sky is clear (2% cloud cover). Working against it: Measured water temperature 37°F. Provisional data. Not available from a verified source for this lake: pressure trend. Confidence is moderate (73%) because some inputs are unavailable or older than ideal.
Poor for kayaking (48/100), from 5 available inputs. Supporting this: No active official alerts for this lake. 1% chance of precipitation. Water temperature is 37°F (combined air+water: 88°F). Cold shock hazard: sudden immersion below 55°F poses serious risk. Confidence is high (90%).
Very Poor / Avoid for swimming (17/100), from 5 available inputs. Supporting this: No active official alerts for this lake. 1% chance of precipitation. Working against it: Measured water temperature 37°F. Provisional data. Immersion shock hazard: water below 55°F poses severe cold shock and rapid hypothermia risk. Air temperature 51°F. Water temperature is 37°F (below 55°F). Severe cold shock and hypothermia hazard upon immersion. Confidence is moderate (77%) because some inputs are unavailable or older than ideal.

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.

Crater Lake currently reports 48°F with wind velocity near 8 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 Crater 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 MFR) high-resolution numerical point-forecast API. LakeRadar uses the official gridpoint for Crater Lake without artificial smoothing or third-party estimates.
