I am a new Private Pilot and the Altitude issue still confuses me. Imagine flying a small Cessna and planning a flight from Watsonville CA to Lake Tahoe CA.
Watsonville is 100' above sea level. So SURFACE setting of Windy is ok to check the winds at the surface level.
But Lake Tahoe airport is almost at 6,300' above sea level...
So, when I want to get an idea the winds on the surface at Lake Tahoe do I need to set my slider to 6000' level or should I leave the slider at Surface setting?
