It will be a sticky end to 2014 in South East Queensland, with a brutal combination of heat, humidity and moisture.

Brisbane hit 29 degrees at 9am with a predicted top of 34 and relative humidity sitting at 70 per cent.

Brisbane is in for a sweaty end to the year.

Amber Young from the Bureau of Meteorology said people often attributed uncomfortable stickiness to humidity, when what they meant was the "dew point" measure.

"Relative humidity is a measure of how full the air is of moisture, but it doesn't tell us how much moisture is in it," she said.
