"The northwesterlies will shift a little more northerly on Wednesday, so they will ease off a little bit."
The rain would "gradually ease away" during Thursday morning, Crabtree said.
"That means a relatively fine afternoon, but the winds will shift more westerly and pick up."
Crabtree said the weather would be more settled on Friday, with cloud and the chance of a few showers later in the day.
"Those showers should clear out by the weekend. I don't know if I'd call it beach weather, but it's definitely a chance to get outside," she said.
"There'll be relatively warm overnight temperatures for the next few nights as well, with 18C for Monday and 16C for Tuesday. It cools off a little bit after that and temperatures become pretty average for this time of year.
"You'll be in the mid-20s range for the next couple of days, and that will drop down to the [lower] 20s over the weekend."
It was looking "more hopeful for a summery period" for the start of next week, Crabtree said.
"We've got a ridge of high pressure moving over the country, but it's a little bit uncertain how much that settled weather will continue into the latter part of next week."
