Welcome to race day for the 14th round of the 2009 FIA Formula One World Championship, the Singapore Grand Prix.

It will settled, with an ambient temperature high of 29 degrees Celsius, and humidity to match.

The race will run over 61 laps of the 5.073-kilometre (3.152-mile) circuit, or 309.316 kilometres (192.209 miles). It starts at 2000 hours local time, which is eight hours ahead of GMT.

There have been several changes to the track. The pit entry has been realigned to leave the track before Turn 22, and the pit exit has been realigned to join the track after the first corner. There are new kerbs on the entry to Turns One and Five, and a new surface between Turns Five and Seven.

The second and third apexes of Turn 10 have been moved left and right respectively to make the chicane slower, and the three apexes of Turn 10 have been redesigned in order to reduce the risk of a car being damaged if it crosses them. The apexes of Turns 13 and 14 have been tightened slightly. And the wall around the outside of Turns 22 and 23 has been moved closer to the track.
