Cotton farmers of Moree in northern NSW have suffered through 36 straight days of at least 35 degrees Celsius, as heat records are broken across the state.

The agricultural town has experienced more than double the number of consecutive sweltering days than the previous record set in 1981.

Cotton farmer Sean Young said the recent weather was taking its toll.

"This heatwave's absolutely roasting the cotton and it's chewing up our natural resources, mainly water," he said.

"We've got cotton now and it's at that stage now where it really needs a drink."

Fellow cotton farmer Dick Estens said he was forced to complete 11 irrigation cycles when ordinarily, no more than nine would be done.

"We've lacked summer storms, you know, cotton love storms," he said.

"We live on hope in the farming game, if the people of Bondi can give us a little rain dance that would be good."

But a cool reprieve is unlikely, with Moree forecast for another week where temperatures sit each day at between 40C and 44C.

Mayor Katrina Humphries said enduring the tough weather was simply part of agricultural life.

"This is the mighty Moree plains, this is the most agriculturally productive shire in Australia," she said.

"We just get on with life because that's what we have to do. There's no point whinging about it."

The town's aquatic centre has experienced a dramatic increase in patronage since the heatwave began in January.

The centre's cheif executive, Scott Hawkins, said he was surprised many were still accessing the naturally heated baths.

"The water is naturally heated so we moderate the amount of water that goes through the artesian pools, but there's still a massive amount of tourists and locals alike who still go into the artesian water," Mr Hawkins said.

"Obviously not in the absolute heat of the day but they're still well patronised in the morning and evening."

People are also travelling far and wide to get some reprieve from record-breaking hot weather across the state's north.

Mr Hawkins said he was expecting a big week ahead with locals not the only ones trying to cool down.

"We've got a lot of people who are travelling from Narrabri or Goondiwindi or Warialda for the day as well," he said.

"So we are getting a lot more people from around our area coming to partake in everything we offer here as well."

Air conditioning under the pump

Meanwhile, air conditioning units in homes and business across the region are struggling to keep up in the searing heat.

Moree-based repairer Mark Davis has reported a 30 per cent increase in the number of jobs he was being called out to.

Mr David said he was being called to areas across the state's north, travelling as far Brewarrina, Collarenebri, Mungindi and even across the Queensland border to Dirranbandi, with his team regularly working 12-hour days.

"We're doing some pretty massive hours and they're occasionally doing it pretty darn tough in the roof, bearing in mind inside a roof you can add 22 degrees to outdoor ambient," he said.

"So when people say it's 29 degrees in my office I can't work, I'd love to invite them up into my office."

Mr Davis was also expecting another big working week with the weather forecast ahead.

"I can't see it getting any easier. I would love a reprieve but that doesn't look like it's on the horizon as yet," he said.

"So yes we're expecting a tough week."
