Those heading to Olympic Park to watch the NRL Grand Final will be treated to ideal spectator conditions with a dry and mild evening forecast.
Minor premiers, the Sydney Roosters, will be taking on the Manly Warringah Sea Eagles on Sunday night to try and take home their first premiership in over a decade. The Sea Eagles on the other hand, will be looking to stamp their authority as the most successful club of the modern era by winning their third premiership in the last six seasons.
Grand Final day itself will be a warm one throughout the Sydney Basin. Temperatures will reach the high twenties along the coast and low thirties in the western suburbs. There will be a bit of cloud around as well, however it will remain dry. Very warm north westerly winds will be gusty at times, reaching around 40km/h during the late afternoon and early evening.
Come kick off time at 7:15pm it will still be reasonably warm at ANZ Stadium with temperatures of around 26-27 degrees. The gusty afternoon winds will have eased as well with winds reaching 30km/h. The temperature will drop throughout the game and by the time the final whistle is blown and it's time to celebrate (or commiserate) it will have cooled to 22-23 degrees. Likewise, winds will continue to ease during the match and will tend westerly ahead an approaching cold front.
The good news is that the cold front isn't expected to move through until after the match has wrapped up. It will also be a generally dry change with isolated showers not coming until the small hours of Monday morning. Those heading straight home after the match should avoid getting wet while those kicking on to celebrate (or drown some sorrows) might get caught in a light shower or two when heading home.
Monday will be a much cooler day with tops in the low twenties along with the odd shower.
