Big and windy for Sun with fresh to strong SW-S winds early, tending strong S’ly all day.
Primary tabs
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
Monster high pressure has barely budged since Wed, maintaining a S-SE flow right up the Eastern Seaboard, with a coastal trough ensuring plenty of unstable, rainy weather.
With a widespread E-SE wind field in the Tasman at a minimum we’ll see moderate amounts of E/SE-E swell through the first half of next week with another round of fun surf on the Points.
A trough of low pressure NE of the North Island is deepening today but moving southwards at a clip through the swell window with reduced swell potential compared to Fridays notes.
At issue is a trough in advance of a major high pressure ridge. At a minimum, the trough will charge up a SE surge along the NSW coast with an increase in S/SE-SE swell later Tues and into Wed
