The wait for a head high plus set was much longer this morning, but they’re still around. At 0800 swell was S-SSE at close to 13 seconds and heights at sea were 1.5-3 metres. At Dee Why the point was busy and the beach continues to offer mostly closing out shoulder to head plus sets. Tide hits a 1.24m high at 1140, weather should be sunny with a high of 20. Water’s clean and on 20 as well.
The Bureau warns that we could still see the odd long-period sneaker set, but the overall trend is downward. Tomorrow could be a small, south magnets-only sort of day. A fresh late afternoon but short-period south pulse with showery weather is on the cards for Friday.
A strong high pressure system is centred over western New South Wales and will drift slowly eastwards, becoming the dominant influence for the next few days. Then a strong cold front is forecast to cross the state between Thursday and Friday, with strengthening northwest winds ahead of its passage. A deep low pressure system may form off the southern or central coastal waters on Friday morning as the front reaches offshore, and this may bring vigorous south to southwesterly winds and hazardous surf conditions with large and powerful waves across the coast through Friday and Saturday.
