They were among dozens of fires burning across the state with temperatures in some parts of New South Wales breaking records for this time of the year, the NSW Rural Fire Service (RFS) said.

Temperatures across the Mid North Coast region soared to 42-43 degrees in some parts.

On Sunday, a small grass fire was quickly contained at Rosewood Road near Wauchope.

To the north, Forestry Corporation brought two bushfires under control, one at Railway Dam in the Maria River State Forest and the other at Campbells Possum Creek Road, South Kempsey.

To the south, the RFS was called to a two hectare bushfire at Cedar Party Road near Taree, a grass fie at Karaak Flat and a three hectare bushfire along the Bucketts Way at Belbora.

The RFS also sent crews west to Nowendoc to contain a small bushfire.

A southerly change moving up the east coast on Sunday evening was delivering welcome relief after a total fire ban across the entire state.

The RFS described the fire conditions experienced across NSW on Sunday as "dangerous".

The 2019 Black Summer bushfires claimed 26 lives and destroyed 2476 properties.

"What we haven't had in the last few years is grass because of the drought and there's been no grass to grow or burn. That has changed significantly.

"These grass fires are quite dangerous. We need to report them as soon as anyone sees a fire - don't assume someone else has reported it. Call triple zero straight away," NSW RFS Commissioner Rob Rogers said.

Residents across the Mid North Coast are urged to ensure they have a bushfire survival plan in place.

The Bureau of Meteorology has predicted high temperatures across Port Macquarie-Hastings will ease from Monday with the mercury to hover between 27-30 degrees throughout the week.
