Tide’s low at @0825 and high at @1505.
A strong, slow-moving high pressure system over the Tasman Sea extends a ridge into northeastern New South Wales, while a weakening trough lies off the southern coast. Northerly winds are expected to increase significantly during Thursday ahead of a vigorous cold front approaching from the west, and are likely to remain fresh to strong as the front crosses the coast during the weekend.
