Last Saturday we experienced a Santa Ana winds "event."
I went out riding and encountered very strong wind gusts. Some of the gusts, especially the gusts coming down Potrero Road were strong enough to temporarily stop my forward movement.
When I downloaded my Garmin date (Garmin 510) it showed an elevation gain of over 3,100 feet.
On Sunday I repeated the same ride, taking the exact same course. The Garmin date for Sunday's ride showed an elevation gain of less than 1,200 feet.
The only difference between the two days were the strong wind gusts on Saturday's ride.
BTW, I do that ride on a regular basis and the elevation results are always the same.
My question(s) then is: do strong wind gusts affect elevation readings and, if so, then why?
