There were a couple of folks bobbing hopefully next to the rocks at Dee Why point before 0800. The wind was coming from the NW at 7-8 kts and the swell out at sea was 1.4 metres at 9 seconds from the south. As the day heats up to the high of 31(!!), the wind will swing to the NE and the swell should pick up a little and by tomorrow morning it could be in the waist plus range as it swings to the NE. The GFS shows it picking up more on Wednesday and going around to the south on Thursday as it gets into the 2+ metre range – but with SE wind.
Go well with your Monday!
A high pressure system over the Tasman Sea currently extends a ridge towards New South Wales, and is directing generally northerly winds over most coastal areas. This pattern is very slow-moving, and northerly winds will persist through the first half of the week, increasing as a cold front approaches. This front is forecast to bring a southerly change to southern parts of the coast later Wednesday, extending to the north during Thursday. Following this, a new high pressure system is expected to drift across from the west at the end of the week.
