As mentioned on Fri, a series of fronts pushing up from Heard Island bring quite an active week of mid-sized surf but finding windows of cleaner conditions will be a challenge.
A large high is now moving into the Tasman Sea and strengthening- that will be the main synoptic feature this week- setting up a deep ridge and a strong E’ly pattern through the Tasman Sea.
Further north an interior upper trough and potential coastal trough/surface low will combine to drive an intense E/NE to NE wind flow through the Coral and Northern Tasman Sea, generating a large swell for the CQ coast.

Generally light variable winds all week should keep conditions clean across all coasts.
Solid surf from the NE then holds through next weekend as a large fetch of E/NE to NE winds extends through the Tasman Sea.
GFS has the more bullish outlook, with a trough or potential surface low forming off the Fraser Coast and tracking south through Fri13th- energising a long E to NE fetch through the Central Tasman to Coral Sea. In effect, it’s a slightly less energised version of the June 2016 Black Nor-Easter set-up.
A generally poor weekend with fun surf Monday and a better swell for Wednesday.
That high will set up a ridge through the week and essentially be the “anvil” for any trough or low pressure development in the Tasman or Coral Sea. A coastal trough off SEQLD/Fraser Coast and interior upper trough combine through the start of next week to increase SE/E winds, initially in the Coral Sea.
