A glorious afternoon and evening are expected for much of the country, with the athletics session getting underway in the Olympic Stadium at 7pm.
The BMX deciders take place in London throughout the afternoon and they should be greeted with sunshine and temperatures of up to 26 degrees.
The women's hockey gold medal is decided tonight and the weather will not be an issue, with temperatures remaining as high as 22 degrees.
Finally, the football at Wembley can expect exactly the same story and the football should be the talking point, not the Great British weather.
