It will be clear skies and light winds tonight as the Wallabies and All Blacks battle it out in the first Bledisloe Cup Test in Sydney.
Sydney turned it on today, with sunny skies allowing the mercury to climb to 24 degrees in both the city and the west. Northwesterly winds were gusty though, reaching 60km/h on the harbour.
Those heading out to watch the game tonight can expect cool and crisp conditions. The winds will have eased significantly, combining with clear skies to allow the mercury to plummet.
It will have dropped to about 14 degrees by kick-off, with relative humidity sitting around 50%, causing spectators to don their scarves and jerseys.
Skies will remain clear throughout the match, with no chance of rain meaning slippery fingers can't be blamed on a wet ball.
By the time the last siren sounds and fans start to funnel out of the stadium, it will have dropped closer to 12 degrees, making for a chilly journey home.
For those who choose to kick on after the match to celebrate or commiserate, it will drop to about 10 degrees in the city and as low as 4 degrees in Campbelltown by the early hours of Sunday morning.
Under these conditions it should be an exhilarating game for players and spectators alike.
