Narrative: While on descent to ZZZ; we checked in with ZZZ Approach and learned that an aircraft had just gone around. Approach stated they went around due to wind-shear on final. Winds at the airport were 190/31G45. After learning about a 20 knot gain and loss on final from that aircraft; we elected to land at flaps 22 to protect the aircraft from over speeding the flaps. While being vectored onto final; we were at 2;100 feet MSL and noted that we had a 77 knot wind at that altitude. We turned final and captured the localizer and glideslope. After configuring the aircraft; we experienced the 20 knot gain and loss but elected to continue as we were above 1;000 feet AGL. We were handed off to Tower and once we changed frequency; Tower was querying an [air carrier] flight in front of us why they went around. They stated it was from wind-shear. We continued on the approach and broke out of the clouds at approximately 500 feet MSL. The entire way down the approach; we experienced moderate to borderline severe turbulence and had airspeed fluctuations of 15 knots. We made it down to the runway; touched down 500 ft past the thousand foot markers and caught a wind gust that lifted us 20 feet above the runway and caused us to float out of the touchdown zone. I immediately initiated a go-around and we climbed to 4;000 [feet]. Due to the turbulence and wind shear; the First Officer and I agreed to not try the approach again. We told ATC we were going to divert to ZZZ1. Our filed alternate was ZZZ1; but I didn't see the point in flying past ZZZ1 to go to ZZZ2. After the go-around we were 300 pounds above our divert fuel. I checked with the Flight Attendant to make sure the passengers were all ok and made a PA that we were diverting back to ZZZ1. After receiving our route and entered it in the FMS; the fuel remaining at ZZZ1 was only 2300 lbs. When we checked on with Center; I declared min fuel to ensure we weren't given any extended vectors into ZZZ1. We continued to ZZZ1 and landed without further incident.




Synopsis: EMB-XRJ 145 Captain reported executing a go-around after a wind gust lifted the aircraft 20 feet above and beyond the touchdown zone.
