If you look at the arrival schedule between 0650 and 0740 which those flights are scheduled to arrive into HKG, there aren't that many flights operated by other airlines at all. Out of the 18 flights, there were only the SQ1 from SFO, HX from BKK which was delayed till 1653 today, SK from ARN and AA from LAX (arrived 0643 today). After the SK flight arrived at 0724, there wasn't any arrival until CX170 from PER arrived at gate at 0807 so I assume the condition was worst something between around 0715 and 0800.
The thing was with fog you are never sure when exactly they will go away so if the captain predicts it will stay for a while, they might just decide to divert somewhere early, refuel and get the new set of crew so that they can get back once the condition improved.
