As of 0600 the MHL buoy was detecting 1.7 metres of 14 sec SSE swell out at sea. Along Dee Why beach that was translating into the odd waist high bump for the patient and well-positioned people in the water. Tide hits low at 0805 and will then run into a 1.4 m high at 1450. Weather should be partly cloudy and a mild 19 ahead of a late S-SE change this afternoon.
The Bureau says the swell should come up, but not this morning. By tomorrow they’re warning it will ramp up into the 2-3 metre range under partly cloudy skies and with winds from the S-SW at 25-30 kts. Friday should see the wind back off a bit and the swell will be off the peak, but still a reasonable 2-3 metres from the south. The models are showing the quality surf lasting into Saturday morning at this stage. Next week currently looks quiet for the front half, but on Thursday morning when yours truly is getting wheeled into the ear surgery at least one of the long range models is showing very good prospects for pumping and clean conditions under sunny skies…
Have yourself a top old day and go well with your plans!
A slow-moving low over the Tasman Sea continues to direct southerly winds along the New South Wales coast whilst a high south of the Bight extends a ridge to southeast Australia. A cold front will move along the New South Wales coast today bringing a strengthening southerly airstream. The high is expected to move over Tasmania in the wake of the front with a ridge of high pressure extending northwards across the state. Another low will develop over the Tasman Sea and as it moves towards New Zealand the ridge will move over the east of the state before a high centre develops over the northern Tasman Sea on the weekend.
