High pressure systems are looking weak and mobile as befits the changing seasons, tracking NE into the Tasman and bringing a N’ly flow across sub-tropical to temperate regions but holding enough strength in the Coral Sea to generate some small rideable waves from mid-week.
Primary tabs
Our summer-style swell producing pattern has broken down and we’re seeing surf ease into the weekend, becoming tiny into next week as high pressure moves towards Tasmania.
A summer style pattern is seeing tropical moisture dragged down the East coast by a trough and deep E/NE-NE flow from a large high in the Tasman, generating large swells for Central QLD.
We have a strong (1033hPa) high in the Tasman, with a deep E’ly flow through the Coral Sea feeding into a coastal trough along the QLD coast. That trough is drawing down plenty of tropical moisture in the deep onshore flow, and generating sizey, stormy E’ly swells for the sub-tropics.
No change expected to the broad pattern next week with strong high pressure moving into the Tasman and a broad, deep E’ly fetch developing through the Coral Sea, with an embedded trough.
No change to the broad pattern expected next week which is strong high pressure in the Tasman and and deep E’ly fetch developing.
Into the mid next week and we should see some real size about as the persistent E’ly winds generate a fully developed sea state through our near swell window.
SE winds have supplied some just rideable surf through today.
Lovely settled conditions at the moment with a broad area of high pressure in the Tasman and a broad but weak tradewind fetch just moving into a better position S and SW of New Caledonia. That will see some small E/NE swell develop through the end of this week into the weekend.
