Narrative:

Aircraft X was on final to runway 28 left following aircraft Y; by about 4 mile visual approach/separation. At about 600 feet aircraft X advised they were going around. Local control asked the reason and the pilot stated 'wake turbulence.' I coordinated the go around with the departure coordinator.at the time; there was a quartering tailwind; ideal for the wake turbulence remaining active in the trailing aircraft's flight profile.
