Narrative:

Aircraft X came inbound from the north and I assigned a runway. The last metar was approximately 45 minutes old at the time. After a go-around it appeared to me the aircraft was coming in too fast and the pilot did not question the wind. After clearing him to land a second time the pilot stated this would be a full stop this time. It was not until he was on the ground taxiing to parking that he asked for a wind check at which point we noticed there was a wind shift and the anemometer reading was increasing before our eyes from 6 KTS to 15 KTS. The direction was from 090 to 140 degrees indicating a landing was made on a runway with a tailwind component that does not comply with the 7110.65; and no wind check was given with landing clearance. I should have checked the wind when giving the landing clearance there would have been ample time to have the aircraft enter downwind for the opposite runway.

Title: Tower Controller described a go around event; failure to notice a wind shift and adhere to required tailwind procedures contributed to the event.
