"On long runs we were really strong and practice was really good," said the three-time champion who is 26 points adrift of Mercedes team-mate Nico Rosberg with three races remaining.
"So strangely Q3 was actually my worst session of the whole weekend so far."
Rosberg, who had struggled to be within half a second of Hamilton for most sessions, managed to close to two-tenths on his final run to take second place on the grid.
"It is always a tough battle to pull out perfect laps when it counts, especially on these tyres, but going into this race we have the right strategy and the car is in a good place for the long runs.
"We have had a lot of pace and that is why we believed it was possible to progress on the soft tyres - and we did our long run on the soft tyres.
