The Sydney games weren't THAT hot, LOL! A couple of the days had temperatures in the low 30C+ range, but basically it was just lovely warm weather 25-30C, and clear skies. There was one night when it rained heavily, but it stopped by early morning and the day itself was only overcast - I remember going out to the showjumping and the grounds were wet, but not slippery because of the good surface.
