A similar thing happened to me, after having completed 3 hours flying after my skills test. It was also the first time I had taked Mr B up with me. Having never experienced it before it was pretty nerve racking, especially on short final, and having a passenger for the first time.
I was set up so nicely on the centreline in a very slight xwind (about 2-3kts I seem to remember), and then suddenly at about 60 feet, I got caught out. A gust of wind pushed me way off the centreline into the helicopter circuit area, and then we got a hell of an updraft followed by a sudden downdraft. The ASI was all over the place. I tried to get it back onto the centreline but whatever I tried to do, the aircraft did the opposite. Just as I had decided to go around, the wind settled down again, and we slowly drifted back onto the centreline. We landed safely a bit further down the runway than planned, not needing the go around after all.
I wet my pants. And so did Mr B.
