Hello Friends,
Nothing much doing at Dee Why this morning. The atmosphere was too thick for my usual start of the day snapshot but there wasn’t anything to take a picture of so far as I could tell. Wind was light SE at 0700 and the MHL buoy was showing about a metre from the east at about 8 seconds apart.
According to the forecast the wind will be out of the south by lunch and it’ll be blowing 20-25 kts. As that happens, the average height of the wind swell at sea will swing around to line up with the wind direction while also building up to about 2 metres. As a matter of interest, the average height down at Eden popped up into the 3 metre range early this morning.
This morning’s batch of swell forecast interpretations is still showing a long period pulse for Thursday. Unfortunately we’re told by the Bureau that the wind will be SE at 10-15kts. Not a great recipe sadly. And it looks as though the generally onshore winds are set to be part of our lives for at least the next week.
Ah well, at least the water has been getting warmer. Summer is coming friends!
Go well with your Tuesday plans everybody.

Weather Situation
A stationary high pressure system over the northern Tasman Sea extends a ridge into northern New South Wales. This high pressure ridge is weakening ahead of a cold front that is currently situated over southern New South Wales. A trough ahead of the front has brought a southerly change to the coast just north of Sydney. The front is forecast to sweep across southeast during today and Wednesday, extending the southerly change to most of the New South Wales coast before it weakens into a trough over the north. Following this, the next high is forecast to move from the Bight to the southern Tasman Sea mid-week, establishing an onshore airstream.
