A south to southwesterly wind change will continue to move along the NSW coast today as a trough and associated cold front move into the Tasman Sea. Winds will tend northerly again and strengthen from Thursday as a high pressure system drifts across the coastal waters. Winds will shift west to southwesterly again over the weekend as a stronger cold front moves over NSW coastal waters, with southwesterly winds persisting into early next week as a series of fronts brush the south of the state.
