The prospect of a four-day, chocolate-filled Easter long weekend just got a little bit sweeter for Sydneysiders.

Blue skies and mostly above-average temperatures are forecast across the city from Good Friday to Easter Monday, in what is shaping up to be a perfect holiday to get out and about.

A top of 24 degrees is forecast in the city on Good Friday, 22 degrees on Saturday, 24 degrees on Easter Sunday and rising to 26 degrees on Monday.

It will be even warmer in the city's west, where the mercury is expected to reach 26 degrees on Good Friday, 24 degrees on Saturday, 26 degrees on Easter Sunday and rising to 28 degrees on Monday.
