Summer came early for the long weekend but Novocastrians shouldn't expect the sunny days to last much longer.
While Monday October 7 reached 31 degrees, Tuesday October 8 was likely to see a 10 degree dip in temperature, according to the Bureau of Meteorology.
Locals and holidaymakers alike flocked to Newcastle beaches and took advantage of Monday's warm public holiday.
Avery Grieve, 10, was excited to practise her skills with her brand new snorkel at the Newcastle Ocean Baths.
Her mum, Tessa Grieve, said she walked with her four kids from King Edward Park down to the Bogey Hole, and then along to the ocean baths.
"It has been a cracker day, it's nice weather, the kids are loving it," she said.
"We've been a bit like a tourist in our own home."
Burying his dad under piles of sand, three-year-old Cooper Ward said he was having a lot of fun.
Decked out in a sharks and dinosaurs swimsuit, he said his favourite thing about the beach was "waves and sharks".
His dad, Steve Ward said they were loving the warm weather, and were just trying to keep their three-year-old entertained.
"We moved over from the UK six years ago, so this is like a holiday every weekend for us," Mr Ward said.
Cars lined up to try and nab a park along the coastline, with holidaymaker, Shantel Neville having to park halfway to Nobbys Beach and walk over to Newcastle Beach this morning.
Patrol captain at Newcastle Surf Life Saving Club, Stephen Cook said it had been a good day with whale and dolphin sightings.
"The crowds have been well-behaved and staying pretty close to shore, and conditions today have been excellent," Mr Cook said.
"The temperature has certainly helped bring people out earlier than what they would normally be," he said.
BoM meteorologist, Belinda House said Monday's weather across the Hunter region was around five degrees above average for October.
"We've had high 20s, pushing into 30 degrees right across the Hunter with clear skies for the day " Ms House said.
"Tomorrow we are going to see a much cooler, southerly change and it's going to push across the coast tomorrow morning, and push inland across the Hunter," she said.
Newcastle's temperature was expected to drop to a maximum of 20 degrees with a high chance of showers on Tuesday with Scone forecast predicting a top of 24 degrees.
"We are expecting that southerly change to bring some showers for the Hunter, there is the chance we may see some thunderstorms as well, perhaps more so through the Upper Hunter," Ms House said.
She said the cool change was expected to hang around on Wednesday, with rainy conditions likely.
Late in the week showers were expected to ease with temperatures starting to slightly warm up, she said.
