BEACHES around Port Macquarie and the Hastings remain open despite the smoke haze that currently blankets the region.

Lifeguard supervisor James Turnham said the situation is likely to remain the same ahead of a Tuesday labelled as being potentially catastrophic.

"(Town Beach and Flynns Beach) are still open at this stage, but we'll take each day as it comes," Mr Turnham said.

Usually weekdays are pretty quiet on the sand and only a few school groups come and go during the day.

"But because school could be cancelled tomorrow and if it ends up being 35 degrees and the smoke isn't too bad we could have a busy day," he said.

"We'll just wait and see what the weather conditions are like. We'll take advice from the other emergency services and follow those."

Mr Turnham said it was difficult to predict whether beaches would be closed tomorrow, but the health of lifeguards would remain the main priority.

"While ever the lifeguards are comfortable being out there the beaches will stay open," he said.

"It is a tricky one because things like this due to smoke don't happen too often, so the health and safety of our lifeguards comes into play.

"If they're not comfortable with the air quality or the smoke and they think their own health is going to be an issue then we'll have to close the beach."

A final decision on beach closures with the mercury set to soar into the mid-30s won't be made until the morning.

"We'll plan on turning up and assessing at 9am," Mr Turnham said.

"It will all depend on the wind direction and whether the smoke is going to affect Town Beach or not.

"We'll try and provide a swimming spot if possible, otherwise if we deem it to be a health and safety issue we won't be putting the flags up."
