MADEIRA, May 9, 2014 (AFP) - After the whole of Thursday's action was cancelled due to the foggy conditions, Friday saw a late start and an early finish with around half the 144-man field yet to begin their first rounds.
All in all it was a miserable start to the European Tour's 1,500th official event at the Clube de Golf do Santo da Serra venue located 700 metres above sea level.
Henry had enough time to fire four birdies in his opening five holes.
A bogey at the 17th hole, his eighth after teeing off at the tenth, stalled his progress but he bounced back with a birdie at the 18th followed by three more at the second, third and seventh.
That moved the 27-year-old Scotsman to seven under par but he struggled to back to back bogeys at the eighth and ninth, finishing two shots clear of Andrew Marshall, Pedro Oriol of Spain and Martin Weigele.
Leading first round scores in the Madeira Islands Open, Santo da Serra, Portugal on Friday (GBR/IRL unless stated, par 72).
Note: Tournament shortened to 54 holes after fog wiped out Thursday's action.
