I'll be arriving at HEL's Terminal 2 on 17 Sep 06:00 (flying onward at 17:10).
This means that after taking a bus to Helsinki, I'll arrive quite early to the vicinity of the central train station.
1. Can you suggest what to do in central Helsinki at around 07:30 (in mid September) ?
2. A Google search suggested that HEL's temperature in September is 8.7-14.3 °C: is that data correct?
