Ahead of today's Sprint the air temperature is 32 degrees C, while the track temperature is 36 degrees.
As you are no doubt aware, in order to secure his third (successive) title, Max Verstappen only needs to score three points this evening, and starting third one the grid one could say that he's already halfway there.
Starting ahead of the Dutchman are the two McLarens, both of whom must really fancy their chances.
The result and championship aside, one thing that will be under scrutiny this evening is the tyres following this morning's announcement from the FIA.
The Sprint is 19 laps and thus far no driver has gone that distance using any of the compounds.
All weekend we have seen surprises courtesy of the wind and track limits, which at times have appeared to work in tandem, especially where the Ferrari's are involved.
A good result from Perez today could delay the inevitable, but with the Mexican starting from eighth it is likely that Max will put us all out of our misery.
