Out at sea the ocean is pretty rugged looking this morning, but inshore the light (and cold) westerly was keeping things comparatively clean in the south corners. After peaking at close to 5 metres last night, as of 0700 swell was 3.7 metres from 175° (basically dead south) at nearly 11 seconds apart. So waves were in the waist and a bit range at Collaroy and 2x that at Dee Why. High tide was at 0600 this morning and is now dropping to the low at 1130. Swell should fade slowly during the day, but not by a huge amount. Tomorrow should see a few more surf options for the early as we get into the chest to head high range at magnets. Thursday is fade out day with maybe a few little fun ones in the morning. Right now the weekend looks potentially hopeful on some modelling…
A few piccies for you…
A deep low pressure system lies over the Tasman Sea, while a high is centred near the Bight. The pressure difference between these systems is generating vigorous south to southwesterly winds along the New South Wales coast. Rough seas and an increasing swell are accompanying these winds. Conditions are forecast to ease today and Wednesday as the low moves further away to the east, and the high drifts overhead. Late on Thursday and during Friday a southerly change is expected as a front clips the south.
Forecast for Tuesday until midnight
