Gales out of Bass Strait get more of a NW tilt o/night into Sat morning which should generate another round of N’ly windswell.
Primary tabs
The more N’ly tilt in winds across Bass Strait later tomorrow and o/night into Fri should lead to another burst in N’ly windswell for Fri.
The pattern of strong, zonal W’lies tied to polar lows and embedded cold fronts and weak mobile high pressure won’t offer much for NETas but we will see some small NE swells generated by radial spread from gales out of Bass Strait this week.
The coming period will become slow as the zonal westerly pattern kicks in across the state.
More small NE windswell pulses on offer next week, but the zonal flow is expected to strafe Tasmania with strong and gusty W-W/NW winds for most of next week so surfing conditions will be rugged.
A deeper fetch now operating near New Zealand longitudes is better aimed at Pacific targets (some to Fiji, most to Tahiti) with some strong sideband S/SE groundswell due tomorrow.
Tues should see better quality S-S/SE groundswell fill in from the deeper fetch in New Zealand longitudes.
Plenty of size Sun as the Tasman Sea trough of low pressure gets supported by a deeper southerly fetch associated with a complex polar low.
Winds off the Tasmanian coast and up into Bass Strait are tending more N’ly over the short term producing some small NE windswell.
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. That will be too far north to generate any meaningful swell for NETas under current modelling.
