Good for boating (85/100), from 4 available inputs. Supporting this: Wind 5 mph from the south-southeast. Gusts to 12 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 (82/100), from 6 available inputs. Supporting this: Wind 5 mph from the south-southeast. Measured water temperature 57°F from a representative gauge 6.9 mi away. Provisional data. Not available from a verified source for this lake: pressure trend. Confidence is moderate (72%) because some inputs are unavailable or older than ideal.
Good for kayaking (85/100), from 5 available inputs. Supporting this: Wind 5 mph from the south-southeast. Gusts to 12 mph. Confidence is high (90%).
Poor for swimming (42/100), from 5 available inputs. Supporting this: Air temperature 91°F. 0% chance of precipitation. Working against it: Measured water temperature 57°F from a representative gauge 6.9 mi away. Provisional data. Cold water hazard: thermal protection recommended below 60°F. Water temperature is 57°F (below 60°F). Immersion requires thermal protection. Confidence is moderate (75%) 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.

Lake Sonoma currently reports 84°F with wind velocity near 10 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 Sonoma 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 MTR) high-resolution numerical point-forecast API. LakeRadar uses the official gridpoint for Lake Sonoma without artificial smoothing or third-party estimates.
