Narrative: We set up the RNAV Y Runway 21 to ABQ; with a gust; correction of a target ref plus 20. We were cleared for a visual but followed the RNAV. We got some up drafts off the hills so we dropped the gear early and were stabilized with flaps a little more than 2;000 feet above the ground. On the initial stages of approach; the tower was calling wind shifts on our approach with some gusts; and one shear of 20 knots. There were only green returns on the radar with a little visible Virga on the west edge of the valley floor. Shortly after Tower called the winds again; without reporting windshear; then the aircraft in front of us went around. We continued; I was flying and the Captain stated he would call out airspeed trends from the HUD. About 1;800 feet; he called for power even though we were two knots fast. I added a little and speed dropped right back down on target. I was on autopilot with autothrottles so I just overrode them by pushing it up. Around 1;400 feet; he called for power again; then more power. I pushed it up again but this time came within two knots of overspending the flaps. So I disconnected autopilot and autothrottles and picked the nose up slightly; which made us very slightly high on the VASI; two red; one white; and one just starting to turn white. The Captain said the speed vectors trend on the HUD were jumping; so he had the aircraft. Right after I called 1;000 feet; we seemed stabilized. I think about 700 feet the speed jumped up and down. Almost simultaneously I think Captain was pushing power up for a go-around; we got a report of a microburst and then the windshear icon. I said windshear; as I noticed the Captain was already starting to escape. I called our climb of 2000 fpm; then called it again and all indications of shear stopped. We cleaned up; Tower gave us a climb to 9;000 feet and we proceeded to ABQ for to hold and notify Dispatch. The Captain gave me Pilot Flying duties again; as he talked to Dispatch and we evaluated options. We had fuel to hold for a long time; we were tankering. The winds shifted again and Tower asked us if we wanted Runway 8; and we declined. After a few Guinea Pigs; tried and got in without windshear; and the winds stabilized for a while; we joined the pack and landed on 8. At some point I told the Captain I thought I saw the airspeed jump into the red; flap overspeed as we were starting to go around. The Captain said we did not; he never saw an overspeed on the HUD. I thought it was three knots. When we pulled in the gate we had a flap overspeed message; so the Captain called Dispatch/Maintenance to talk it over with them and put it in the book.If I had to do it again; with a wind shift and Virga in the area; I would have gone around the minute the [plane] in front of us did. I talked to an old (carrier) Pilot years ago who said Virga and mountains do not mix.




Synopsis: Air Carrier First Officer described a windshear event on final to ABQ Runway 21 which resulted in a go-around and ultimately a Runway 8 approach and uneventful landing. A flap overspeed occurred during the go-around.
