Monday update:
Sydney's weather for the October 5 public holiday looks set to be similar to the weekend.
The Bureau of Meteorology forecasts Sydney will reach a top of 33 degrees, and be hot and sunny. There will be light winds becoming west to northwesterly 15 to 20 km/h in the middle of the day then becoming light in the early afternoon.
The temperature for Tuesday will be a high of 29 degrees ahead of a cooler change for Wednesday, when it will be 23 degrees and cloudy with the possibility of rain.
Saturday:
Go to an air-conditioned cinema and watch the movie Everest.
Images of mountaineers stuck in snow and ice are sure to have a cooling effect with temperatures predicted to reach 35 degrees on Sunday.
Buildings with thick walls of sandstone walls like museums and art galleries will also make a good retreat.
NSW Health has tips for staying cool on its website. Drink plenty of water, keep your body and house cool and watch out for children and the elderly. http://bit.ly/1abfmKy
Forecasters said temperatures will be even higher than 35 degrees away from the coast, but it will not be the hottest day of the year.
The heat, expected to extend well into the middle of next week, is due to a slow moving high pressure area centred over the east coast of the country.
On Saturday, Penrith at 35 degrees and Richmond at 34 were hottest and can expect rather higher temperatures on Sunday, while Sydney managed 28 degrees.
Saturday's grand final was the hottest in the AFL's history after Melbourne exceeded its expected maximum temperature.
The temperature reached 31.3 degrees, exceeding the previous hottest grand final day, which was in 1987, when it reached 30.7 degrees.
There are no fire bans in NSW but fire risk is considered 'high' for the eastern half of the state. The Bureau of Meteorology says that the UV Index, predicted to reach 8, is considered 'very high'.
The Bureau of Meteorology was pretty confident of one other thing – the chance of rain before next Thursday is about nil.
