Fine conditions with the subtropical high pressure ridge to the south. Afternoon sea breezes as the southeasterly pressure gradient bends with solar heating, the sea breeze would be rather strong particularly over coastal and riverside suburbs.

Moist onshore flow establishes on Thursday leading to plenty of clouds and the chance of showers.

A weak cold frontal passage on Friday brings some showers to the region and still slight chance of showers with stratocumulus clouds in the wake of the cold frontal passage on Saturday. Fine conditions again thereafter as subtropical high pressure ridge builds to the south.
