A north-westerly wind is blowing across the region at 41 kph, pulling in hot, dry air.
The NSW Ambulance Service is urging people to stay hydrated and not underestimate the heat.
“Make no mistake, everyone in the community should understand heat can kill - sunburn, dehydration and heat exposure can lead to heat stroke," Acting Chief Superintendent Ian Johns said.
10am UPDATE: Emergency service crews have gathered at the Illawarra Rural Fire Service headquarters in Albion Park Rail.
They are monitoring weather conditions from the command centre and are poised to react the moment a fire breaks out.
Illawarra zone RFS Superintendent Richard Cotterill said representatives from numerous agencies, including police, the State Emergency Service (SES), Marine Rescue and the Volunteer Rescue Association (VRA), were on standby at the base.
‘‘All the agencies are here at the command centre so we’ve established very robust communication between all the services,’’ he said.
RFS crews and police are also working to prevent fires from breaking out.
‘‘We’re working with police to do additional patrols in certain areas to make sure people aren’t doing the wrong thing,’’ he said.
‘‘National parks are closed and we’ll be patrolling those areas.’’
Mr Cotterill said RFS community engagement teams would be roaming across the region throughout the day to provide information and advice to residents.
Representatives from Wollongong, Shellharbour and Kiama councils, the Sydney Catchment Authority, NSW National Parks and Wildlife Service, the NSW Department of Agriculture and Department of Community Services are also in attendance at the command centre.

Although no roads are closed, the RFS are urging residents to avoid the area.
Should the fire escape containment lines, a rapid spread towards the east would occur.
Residents living or holidaying in the Wandandian, Sussex Inlet, Swanhaven, Cudmirrah and Berrara areas should move to a built up area such as Nowra or Ulladulla town centre for the day.
