A troughy pattern exists through the Northern Tasman down to the South Coast with the remnants of TC 10P (named by JTWC but remained a cyclone for less than a day) drifting in a SW direction from out near New Caledonia. A small low pressure cell near the South Coast is slowly drifting south leaving a variable flow in it’s wake across the f/cast region.

Weak high pressure sits in the Tasman now, directing freshening NE winds across the Central/Southern NSW Coast as a trough and front approach from the W and SW. The trough will bring a robust S’ly change to the NSW Coast through Thurs, extending up into the sub-tropics during Fri. S’ly winds and swell quickly build in the wake of the trough.

We’ve got a weak, blocking pattern with high pressure (1025 hPa) right smack bang in the middle of the Tasman directing an onshore flow along the Eastern Seaboard. NE across Temperate NSW and SE-E in the sub-tropics. Warm SST (sea surface temperatures) are helping morning land breeze development so conditions should be relatively clean through the early sessions.

We currently have a weak, troughy pattern in the Tasman Sea, with continuing instability across the tropics in the wake of an active, monsoon pattern. High pressure is expected to drift south of Tasmania this week, with a typical Summer NE wind pattern becoming established. Remnants of low pressure near New Zealand are offering up minor fetches out of Cook Strait (currently) and near the South Island which will supply a few small pulses of swell this week.
