Darwin has sweated through its hottest January day on record.
The weather bureau reported a temperature of 36.1 degrees Celsius at 1:30pm today, the highest January temperature since record keeping began in 1941.
It was the second day of record heat in the Northern Territory capital.
Yesterday the temperature reached 36C, breaking the previous January record of 35.6C set in 1985.
Humidity levels have swung between about 50 per cent and 70 per cent on both days.
Senior forecaster Graham King says the mercury began falling this afternoon after the arrival of a sea breeze but tomorrow is expected to bring another possible record breaking day.
"Temperatures just keep rising," he said.
"There has been no cloud cover out there and there is a lot of dry air around."
The hottest day recorded in Darwin happened in October 1982 when the temperature hit 38.9C.
Mr King says there is unlikely to be any relief from the heat until the end of the week.
"We will probably be waiting now for the monsoon to develop later in the week," he said.
