Clerk of the course Michael Prosser said on Wednesday afternoon: "We got off lightly as there have been heavy showers around and it's breezy and sunny at the moment.
"The GoingStick has eased to 6.8 from 7.3 and I've changed the going with the final furlong and a half slightly slower."
Prosser added: "The forecast is dry for the start of Thursday with some more showers coming through after racing. The course has taken a lot of rain but is in fantastic condition and we've kept this strip especially and it's in top shape."
The feature race on the opening day is the Princess of Wales's Goldsmith Stakes and trainer William Haggas has been delighted to see the rain fall in recent days for his leading fancy Harris Tweed.
"He's very well and it's been showery here today so that should suit him. He likes softer ground," the trainer said.
The wet British weather continues to frustrate Ortensia's trainer Paul Messara, although his mare will line up in the Darley July Cup on Saturday regardless of the conditions.
"It's mid-range slow by Australian standards," Messara told Sydney's Sky Sports Radio. "If the weather forecast is right, with two days racing prior to our race it could end up more like a heavy. She gets through it but she doesn't thrive.
"But quite a few of the fancied runners don't like it so the field could drop away a bit. Bated Br eath doesn't want it wet at all."
He added: "I think the most important thing is balance and getting into a rhythm early. I think we would be willing to sacrifice a position to get her balanced because that is the most important thing.
"Where we draw and how many starters there are will play a major role. The first 600 metres will be about about balance and getting her into a rhythm. She has had two goes on the July course and attacked the downhill part of the straight really well."
