Sunday is unfolding as a great day for sport, including the Bathurst 1000 and the SANFL Grand Final. The weather is ripe for entertaining battles on the V8 car race and the last aussie rules game of the season. Sunshine and gentle winds will dominate both Bathurst and Adelaide for one of their biggest sporting days of the year. Cold mornings will turn into sunny, mild afternoons. Tens of thousands of spectators at each event will be donning sunnies, hats and sunscreen as they peel off the layers into the warming afternoon. Bathurst's Mt Panorama is steadily warming up after a chilly start to the day. Shortly after sunrise the sound of unzipping tents and swags was greeted by a temperature of only four degrees, one degree below average for this time of year. For the start at 10:30am it should be about 13 degrees, warm enough to heat up the tyres and get drivers setting fast early lap times. By about midday it will have reached 15 degrees and the wind chill will have virtually diminished, making it one of the most pleasant afternoons the race has seen in recent years. top of 18 degrees is likely, one degree below average, conducive for a fast race. At Football Park in Adelaide it was also a nippy start to the day, as cool as six degrees at sunrise. Much like in Bathurst, it will warm up to about 18 degrees this afternoon and the wind will hardly have an impact. This should make it an entertaining contest between the Norwood Redlegs and West Adelaide Bloods for the South Australian National Football League Premiership.
