AFL grand final weather forecast: Here’s how it’s shaping up in your city

Tens of thousands of fans are gearing up to watch the Sydney Swans and Brisbane Lions face off in the AFL decider at the MCG on Saturday.

Those who aren’t among the lucky ones to make it to the game are planning ways to make the most of the big day, so how is the weather set to hold up?

Several months’ worth of rain is forecast to hit much of the country as a rain band sweeps across this week.

The near-nationwide soaking kicked off in northern WA at the weekend and will spread to the eastern states through to Thursday, according to the Bureau of Meteorology.

But some of the grim weather is set to ease up towards the end of the week ahead of the grand final.

Here’s a state-by-state breakdown of what you can expect.
