Well Beanz,
I was on the Rebel ride today, so we had strong headwinds going up Jamboree, then worse over on Cannon and up Serrano.
Not only headwinds, but gusting sidewinds, from one side, then (when you corrected for one side), you'd be hit by a side wind (or side head) from the opposite side! From there it was East Canyon Rim to Nohl Ranch, then left up the 12% side of Imperial, but at least it was with a tail wind.
Fortunately, all of our riders (at least the ones I saw), were intelligent about it, plus we only hit 30 with the tail wind on the final approach to the park on Jeffrey.
Still, it pays to be extra careful when the winds are that strong and unpredictable.
