RESIDENTS on the Northern Rivers are urged to monitor weather reports and health advice as heatwave conditions are expected to continue on Sunday.
The Bureau of Meteorology warns temperatures are generally expected to increase over the weekend and will stay high into Monday.
"We've had a sustained period of light winds from central Australia," A BOM spokesperson told The Northern Star on Sunday.
"That's allowed allowed heat to build up, and a north westerly wind is bringing that hot air over NSW, predominantly over central and southern parts of NSW.
"Today, temperatures in the mid-40s are expected in Sydney and in the Northern Rivers, temperatures will be in the mid-30s, and tomorrow temperatures will be similar.
"Grafton will have 35-36 degrees for a few days in a row, Lismore will be around the 33 mark.
"On the coast we're at the high 20s or low 30s, and that's because of the effect of a sea breeze."

Police reminded motorists it's not only an an offence for children or pets to be left unattended in a vehicle, it can be deadly.
Despite the recent warnings, in December a dog died after being left in a car at Rose Bay, and in a separate incident a 32-year-old man was arrested and charged at a Guildford hotel after he allegedly left a six-year-old boy in a car.
Some residents are at higher risk of heat illness, especially if they are older, live alone or are socially-isolated.
Tourists, campers, and other holidaymakers who are in unfamiliar environments are urged to take extra care, especially when swimming.
