Narrative:

Approximately 10 mi northwest of scottsdale airport, I reported to scottsdale tower that I was inbound for landing with ATIS information. Tower directed me to report wide downwind abeam chauncy ranch for runway 21. (ATIS said runway 3 was active.) believing a runway change was in progress, I next reported right downwind for runway 21 abeam chauncy ranch. I was told to follow an aircraft on left downwind. I reported aircraft not in sight. Next I reported a wide right base for runway 21 and asked where was my traffic. Tower indicated my traffic was on a 1 mi final. I reported that I did not have the traffic in sight. I then turned final for runway 21 and noticed opposing traffic rolling out on runway 3. At this same time, tower called asked for my position and that I was not in sight. I replied that I was on a 1 mi final for runway 21. Tower indicated runway 3 was active for the first time. I went around and entered a left downwind for runway 3. When I told tower that they had directed me to runway 21, I did not receive any acknowledgment. I was then cleared to land runway 3 with no further discussion about this incident.
