The rain abated before the start of the session at 13:30 local time, but the pitlane remained closed while track workers attempted to clear off standing water, preventing any running in the early stages.
With 39 minutes left on the clock, the pitlane finally opened, avoiding a repeat of the 2023 scenario where fans witnessed just five minutes of FP1 action due to CCTV issues.
Mercedes driver
Lewis Hamilton was first out on intermediates for a few sighter laps while Sauber’s
Valtteri Bottas had the less popular full wets bolted on, but he soon followed Hamilton’s lead as it became clear the track was ready for the green sidewalled inters.
As more drivers ventured out on the slowly drying circuit, Bottas’ team-mate
Zhou Guanyu caused a brief red flag by losing control over his
Sauber and clattering the outside Turn 5 wall with his rear-left corner.
Following a quiet spell, there was a late flurry of activity in the final six minutes when a clear dry racing line encouraged most drivers to go out on soft slicks.
After slipping off the track in Turn 2, Leclerc briefly took over the lead from team-mate Sainz, before
McLaren man Norris went top with a 1m24.425s.
Sainz reclaimed second from Leclerc, with Hamilton taking fourth ahead of world champion
Max Verstappen in the Red Bull.
Red Bull’s Perez and the second Mercedes of
George Russell rounded out the top ten.
Alpine reserve driver Jack Doohan got little enjoyment out of taking over Esteban Ocon’s car for FP1, with the Australian restricted to three laps without setting a time.
Zhou and Williams’
Alex Albon also finished the session without a lap time on the board.
More rain is expected for Friday afternoon’s second practice session which follows at 5pm local time.
