“It’s going to be a warm one across Sydney and New South Wales,” Hines said.
“We are forecasting to reach 36 degrees at the stadium and if that comes through it will make it the hottest grand final on record, topping the 34.7 degrees in 2014.
“It’s looking to be a scorcher on the field.”
That’s a whopping 14 degrees above the average October maximum of 22.2 degrees, and not far short of the October record of 38.2 degrees (in stats going back to 1858).
Total fire bans have been issued for greater Sydney, the Hunter, the far south coast and across north-western NSW – with the fire danger rating also sitting at extreme in those areas.
Hines said hot, gusty north-westerly winds are expected to cross the state today, increasing the risk of fires.

“We have all the ingredients for the high fire danger,” he said.
“We have the warm sunny conditions, but as the day goes on, we will see the wind pick up across coastal areas and we will see the hot and dry winds build – which means the fire risk increases.”
