Cold, windy, clean

Hello Friends,

Cold and windy start to the day, but the skies were largely clear and the south swell has picked up overnight. At 0730 it was dead south at 3 metres with an average period of 9 seconds. Wind is straight offshore at 20-25 kts and it’s clearly holding a fair amount of the swell offshore. Sets at Dee Why point were around the shoulder to head high mark, but pretty inconsistent. It’s a foot or two bigger up the beach and the sets are considerably more frequent.

The offshores are set to swing gradually around to the south by midday and then the Bureau tells us that we’ll be seeing 35-45 kts.

Tide was low at 0730 and will hit a modest high around 1420.

Swell is expected to build from the present 3-5 metres to 5-6 metres by dark and then to stick around at about that level through tomorrow.

Unfortunately, surf options look like being pretty limited thanks to the powering southerlies – which are forecast to be strong through Sunday and into early next week.

Definitely not beginner material this weekend.

Go well with your Friday one and all!
