My recommendation would be to try and listen to the LIVEATC.net recording (if available) for your flight/airport of landing. Try and see if ATC directed the pilot to go around (they might even state the reason why like traffic not clearing, separation issues, ground traffic issues, etc). Or perhaps the pilot made the call for a missed approach due to winds, clouds, etc.
At my airline we keep internal records for go-arounds/missed approaches for engine cycle calculations and FOQA records. I don't know of any public database of this info. From a pilot's perspective it's all random. I have gone 8 months without a missed and then had 3 within one week. Keeps things interesting!
