Extreme fire danger, temperatures in the mid-30s: Far South Coast to swelter through another risky day

A top of 34°C is forecast for Batemans Bay on Tuesday (October 3), while Narooma is facing a top of 32°C.

It's also predicted to get to 32°C in Bega and Merimbula.

A high pressure system off the coast is the culprit behind the unseasonably warm weather; during late September and now into early October, temperatures has risen well above the monthly averages.

Bureau of Meteorology spokesperson Dylan Bird gave a rundown of the weather systems at play.

"Generally speaking, we've got a high [pressure system] over the Tasman Sea, and this approaching cold front from the west," he said.

"Between the two, we have these strong northerly winds which are dragging heat from the interior of Australia into New South Wales. And we've had fairly continuous northerlies over the last week and into early this week.

"It looks like that heat is very much peaking tomorrow in many areas, particularly areas close to the coast.

"Tomorrow we'll see temperatures up to 14 degrees above the average for this time of year - so that's quite warm for the south coast."

With extreme fire danger forecast for the Bega Valley and Eurobodalla shires, advice from the Rural Fire Service NSW is 'take action to protect your life and property'.

It is recommended to check your bush fire plan and ensure that your property is fire ready.

A total fire ban will be in place for the Far South Coast - Eurobodalla and Bega Valley - on Tuesday.

Under a total fire ban, fires out in the open are not allowed.

Activities which can potentially cause a fire or throw sparks, including (but not limited to) welding, grinding or gas cutting, are also prohibited.

Fortunately, residents and visitors (and firefighters) can expect some relief as a cold front swings through later in the week, Mr Bird explained.

"It's going from hot to cool... the [cold] front will reach the south east early on Wednesday, and with that it looks like temperatures will swing back in that direction," he said.

"Looking at average temperatures, those will be between two to six degrees below the monthly average."

Out on the water, conditions are more of a mixed bag: wind warnings are likely for much of the NSW coast, and potentially some serious surf conditions in the south.

A strong wind warning is already in place for the state's marine areas as of Monday (October 2), and is set to stay that way tomorrow.

"We're also likely to issues a hazardous surf warning for the Batemans and Eden Coasts for late Wednesday to early Thursday," Mr Bird added.
