Wind was out of the north at around 10-15 kts and the tide was dropping to a low around 1140, when I checked the situation for the first time today. It was around 0800 and at that stage the MHL buoy was showing a couple metres of NE wind swell with a period of 7 seconds. As my picture shows, there were sets into the chest high range along Dee Why beach. But the water looks pretty ordinary following days of heavy rain. We’ll need at least a day or two of sunshine to knock off the pathogens in the upper layers of the water column.
The NE’r will work its way up into the 20-30 kt range this afternoon and that should mean the potential for some activity in the north corners.
This morning’s swell models are showing the NE wind swell sticking around through tomorrow and then we go back into southerly conditions once again for a few days before the energy moves more to the SE toward the end of the week – and possibly ramps up into the overhead range around Thursday.
The Bureau says we can expect have late rain after a day of partly cloudy conditions.
Have yourself a great Sunday!
A low pressure trough over inland NSW is moving northeast as a high pressure system strengthens in the Bight. A high pressure system in the southern Tasman Sea extends a ridge to the New South Wales north coast. A southerly change is expected to the far south coast later today as the trough moves northeast. This change will extend gradually to the far north coast by early Tuesday.
