Sydneysiders can look forward to the coldest temperature of the year so far on Monday morning.

A strong cold front will cross the Harbour City on Sunday morning, although hardly any rain expected from this system.

The airmass behind the front will be significantly drier, which means it will feel a few degrees colder than the actual temperature when also factoring in the breeze.

The mercury will plummet overnight Sunday into Monday, due to clear skies and offshore winds associated with a building high pressure ridge.

Temperatures for most inland areas are expected to dip to around 7-8 degrees at around dawn on Monday, including Richmond, Penrith and Parramatta; this represents around 4-5 degrees below average for mid-April.

Sydney Observatory Hill should see a minimum of around 10 degrees on Monday, with just the coastal fringe of the city will remaining comfortably in double figures, due to the warming effect of the ocean.
