A pair of weak cold fronts are expected to pass over Tasmania in the short term, generating small S swells which will overlap with the last pulses coming from the polar low now SE of New Zealand. A dynamic, troughy pattern looks set to unfold over the weekend.
Primary tabs
High pressure is approaching Tasmania with a weak trough expected to linger in the Tasman and across the North Coast over the weekend and lead to mostly light breezes, especially Sun. A complex polar low is approaching the NZ corridor and although the frontal progression looks a notch less favourable for swell production up the East Coast we’ll still see S’ly groundswell pulses over the weekend
Local swell sources dry up but polar lows better aimed at Pacific targets will send some long period S swell up the pipe over the weekend and early next week before a more subdued outlook takes hold.
The remnants of the weekend’s low pressure trough are currently being reinforced by another cold front and expected to form a broad low pressure system in the Tasman in the short term which will supply some fun waves this week with an easing trend into the weekend.
Big and windy for Sun with fresh to strong SW-S winds early, tending strong S’ly all day.
Backed by a strong high we’ll see very tight coastal pressure gradients with strong to potentially gale force S’lies Sat and a large windy S swell.
We’ll see some small S/SE-SE swell as the new high pressure ridge builds a windfield in the Coral Sea and Northern Tasman but this will be smaller and weaker than previous swells of this ilk
We’ll see some long period S swell filter into NENSW across Sat a’noon at S facing beaches, holding through Sun.
The resulting high pressure ridge is leading to deep onshore flows and a trough along the coast is expected to move offshore Sun and form a broad trough of low pressure early next week.
In fact, it becomes reinforced by a new high and this peanut high straddling Tasmania will hold a firm ridge along most of the Eastern Seaboard with another working week of SE winds, gradually backing off into the weekend. A stalled trough looks to linger off the coast bringing plenty of unstable weather and possibly windows of lighter winds
