Don't know but assume you're confused by the virtually zero wind and good viz.
Mrs C had two go arounds the other week, in similar conditions. The first was because a cabin crew seat belt was jammed in the cockpit door and said cabin crew couldn't secure them self for landing. The other was (and I'm guessing here based on Mrs C's description) due to not being stable on the second approach, which appeared to come of a quick night circuit.
The point? There are many causes for a missed approach.
