It's a scorcher!

COOMA has baked in searing heat in the first week of the New Year and it is set to continue.

Heatwave conditions have taken grip of much of Australia.

In Cooma the heatwave is forecast until today (Tuesday) with temperatures cooling off on Wednesday to 25 degrees.

Scorching weather began on Friday with a high of 35 degrees.

On Saturday the mercury rose to 37.8 degrees- the hottest day in two years.

The hot conditions continued on Sunday with a top of 36.5 degrees.

Temperatures were expected to reach 35 degrees on Monday and Tuesday, making five days of heatwave conditions for Cooma with temperatures at least 5 degrees above average.

Bureau of Meterology issued a warning last Thursday for extreme heat across the country.

Senior Meteorologist with the Weather Channel Tom Saunders said the hot temperatures will combine with low humidity and strengthening winds to cause severe to extreme fire dangers over most of the state.

A colder southwesterly change is predicted to spread through the southern inland on Tuesday afternoon and a southerly change will push up the southern coast.

Southern NSW Local Health District is reminding residents to take care to avoid heat stroke and dehydration.

Director of the SNSWLHD's Public Health Unit Tracey Oakman said every year, in Australia, hot weather and heatwaves cause illness, hospitalisations and sometimes even deaths.

"Signs of heat-related illness include confusion, dizziness, fainting, nausea, vomiting, weakness, headaches and loss of sweating," Ms Oakman said.

"People showing any of these signs should seek urgent medical attention."
