Windshear gets more interesting with higher winds. I've seen 20 kt. fluctuations on final.
Once arrived at a field with a humongous North crosswind spilling over a ridge just North of the E-W runway and proceeded to have my fillings shaken loose on final
Just about full rudder to keep it straight; then as I came below the trees, the crosswind disappeared and I had to make a very fast uncorrection
The airport operator knew I was coming and drove out to watch the "fun"
