Interesting point about the wind being measured at the top of a pole. Yesterday landing at Cambridge in a C152, the crosswind was gusty and around 20kts. I stuck to it down finals but was 90% sure I was going to have to go around, but in the last 20ft or so things calmed down considerably and in the end it was fine. A wind measured at the top of a pole would have suggested it wasn't possible to land a C152 under those conditions.
