High pressure is weak and mobile at the moment, restricting trade-wind flows in the Coral Sea.

That story continues through the week, with a breakdown of Tradewinds in the Coral Sea and light/variable winds. Great fishing weather for the reef, bad for surf.
The ridge maintaining the SE flow which has been maintaining fun waves for the CQ region is slowly but surely drying up, with a total failure of Tradewinds expected next week, leading to a period of tiny/flat surf.
A broad, angular area of low pressure in the Northern Coral Sea, extending southwards is maintaining good windspeeds in the tradewind fetch at the moment and that is leading to surf punching slightly above it’s weight.
The sheer longevity of the wind field maintain a rideable signal of surf for most days this week.
That will set up a fresh ridge of high pressure along the f/cast region over the weekend.
While the south swell being generated is of no use to the CQ coast, the ridge that develops as the strong high moves into the Tasman brings increased SE winds along the CQ coast and extending out into the Coral Sea later this week.
Meanwhile, out in the South Pacific a sub-tropical low is deepening well E of the North Island with a well aimed fetch expected to be aimed at the sub-tropics generating a long range E’ly groundswell for the weekend.
Low slipping through South Pacific sends good swells to exposed breaks this week, with small background surf before and after.
Unfortunately, the low now moves southwards, dragging the E’ly flow with it, out of the CQ swell window.
