Red weed, little swell and warming conditions.
Port Macquarie Lifeguard spokesperson Blake Polverino says swimmers should probably head to Lighthouse Beach during this week.
Despite the continued north easterly winds and red weed, there are still many swimmers keen to have a dip and find some relief from the increasingly warm weather.
"All beaches are looking okay for this week, particularly in the morning," he said.
"Flynns Beach still has a lot of red weed - but most other beaches are not too bad.
"But there will be north easterly winds returning through this week, which will mean that Lighthouse Beach is your best bet."
Mr Polverino said swimmers should swim to their ability, obey all warning signage posted by lifeguards and volunteer surf lifesavers and swim to waist deep only.
"And swim between the flags too," he added.
Meteorologist with weatherzone Tom Hough says this week will feature mostly sunny skies with temperatures climbing into the low 30s.
"Monday will see a maximum temperature of up to 30 degrees - which is two degrees above the average for January," he said.
"Tuesday and Wednesday will increase a further one degree while Thursday and Friday will climb further to 32 and 33 degrees.
"The minimum temperatures will be around 20 to 21 degrees throughout this week - that is also two to three degrees above the average for this time of the year."
Mr Hough said hot air is moving ahead of a low pressure trough being funneled down from the north west interior of Australia.
He said north easterly winds will dominate throughout the week.
"Monday will see winds at around 20 kilometres per hour but reaching 25 to 30km/h toward the end of the week.
On the waters, Monday will see significant wave heights of around 2 metres; 2 to 3 metres on Tuesday and Wednesday and Friday increasing to 3 to 3.5 metres.
An easterly swell will prevail for Monday and Tuesday before turning north easterly on Wednesday to Thursday.
The swell will be around 1 to 1.2 metres before dropping to 1 metre on Wednesday.
