He used his time-off over the weekend to head to Coachella.
Hamilton came within touching distance of winning a chaotic Australian Grand Prix last time out.
But Max Verstappen and Red Bull once again proved to be too quick as he his second race of the season.
Hamilton’s P2 result meant he secured his first podium of the season to lift him up to fourth in the driver standings.

He will be hoping Mercedes can consolidate the improvement they showed in Australia by continuing to close the gap to Red Bull.
However, Mercedes, who have admitted their car design is wrong, are not set to bring any car upgrades until May’s Emilia Romagna Grand Prix.
Hamilton himself has revealed his frustrations of the motor he is racing in this term, and now 63-year-old Austrian Berger, who competed in 14 F1 seasons, has urged him to look for a new team.

He told Marca: “If Lewis can’t get a competitive car at Mercedes and also if Red Bull’s doors are closed, why not try Ferrari in case they don’t want to give it up?
“Maybe he can fix the problems they have. A driver’s commitment with a team it doesn’t mean anything, nobody reveals their cards.”
Berger added: “All racing drivers want to drive for Ferrari at least once in their life.
“Almost all the best drivers in history have been there at some point.
“Ayrton Senna didn’t go because he knew that I couldn’t win there, maybe the same thing will happen with Lewis.”
Meanwhile, Hamilton has learned his 2008 F1 title could be under threat after Felipe Massa revealed he is considering legal action over the Crashgate scandal.
This is after comments made by ex-F1 supremo Bernie Ecclestone regarding the deliberate crash of Nelson Piquet Jr at the Singapore Grand Prix.
