What will the weather be for Taylor Swift's Sydney shows?

Fans are preparing for round two as Taylor Swift rests up in Sydney ahead of four back-to-back three-hour Eras Tour performances.

Swift has flown in from Melbourne after performing in front of about 288,000 fans at the MCG over three nights, which were the biggest crowds of her career.

Swifties in Victoria were treated to a warm and dry three nights but fans heading to the Sydney shows might not be quite as lucky.

Here's what we know about the weather forecast for Swift's Sydney shows.

Friday night (February 23)

The Bureau of Meteorology (BoM) is predicting a "very high chance of showers, most likely in the afternoon and evening" on Friday.

There is also a chance of a thunderstorm and southwesterly winds.

The chance of rain is 90 per cent and 2 to 15mm is predicted.

The maximum temperature is 35 degrees.

Although a rainy performance might not be ideal, Swift danced through her Eras Tour show when it poured in Massachusetts for the full three hours last year.

Saturday night (February 24)

BoM predicts the Saturday night show will be cloudy and there is a medium chance of showers but it will most likely be during the morning.

The maximum temperature is 25 and the minimum temperature is 18 degrees... so maybe think about bringing a jacket.

Sunday (February 25)

Sunday only has a 10 per cent chance of rain and is expected to be partly cloudy.

The temperature is a maximum of 25 and a minimum of 17 degrees.

Monday (February 26)

On Monday there is a 30 per cent chance of a shower "most likely later in the day", according to BoM.

The day is due to be a mostly sunny 28 degrees and a minimum of 16 degrees.
