Having started from seventh on the grid on the hard tyres Gasly rose up the order as others pitted, and by lap 44 he was in third place.
Up and down the pitlane drivers were being told that rain was expected but rather than have Gasly wait for a possible opportunity to switch straight to intermediates, the team called him in for medium tyres just a few laps before the rain hit.
He was thus obliged to make a second stop as the rain intensified and take intermediates on his way to an eventual seventh place.
While he was pleased to see Alpine team-mate Esteban Ocon finish third Gasly admitted that he was frustrated by the way his afternoon unfolded.
“I must say I'm really happy for the team,” he said when asked by Autosport/Motorsport.com about the race. “It's a fantastic weekend for us with a podium, also congratulations to the team and to Esteban.
“I must say on my race I'm disappointed and confused because when we're running P3 and I'm going green and we know the rain is coming. I was in the perfect position to just stay long.
“I called on the radio, I wanted to stay long and benefit from the conditions. And then we boxed, and two laps later the rain came. We need to review why we boxed, because there was P3 and P4 on the table for the team, and it would have been a couple more points.
“But once again I don't want to share too much frustration, it's still a beautiful day for the whole team with the podium but we have a couple of things to improve, and we'll do it for next time.”
