Sydneysiders awoke to perfect beach weather this morning but the day has turned grey, and there are showers on the way.
Warm northerly winds ahead of a trough brought Sydney's warmest night in over a week, cooling to just 21 degrees in the city, which is four above average.
Beachgoers were treated to light winds and bright sunny skies in the morning, as well as 20 degree waters. The air temperature warmed to 27 degrees by 9am in the city, while Camden tipped 29 degrees and Gosford reached 30.
The beach weather was only short-lived though, thanks to a southerly change that arrived with the trough causing it to drop to 21 degrees just after 10am. Skies turned grey and winds became gusty, reaching 69km/h on the harbour and 87km/h at the airport, sending beach umbrellas flying.
For the rest of Sunday it will be cloudy with a few light showers and the chance of thunderstorms, more likely in the west. Southerly winds will ease slightly during the evening but remain gusty well into Monday morning, especially along the coast.
During Monday a high pressure ridge will build along the NSW coast, maintaining moist south to southeasterly winds with the chance of showers until the middle of the week.
