Sun, sand and Santa ... it's the perfect combination this Christmas Day with Brisbane expecting "hot and humid" conditions and a top of 33 degrees, according to the Bureau of Meteorology.

However, a refreshing sea breeze has been forecast to lower temperatures by several degrees along the coast on Monday, but the bureau warns the cool winds will precede potentially severe storms, so beach-goers need to be ready to move the festivities indoors during the late afternoon.

BoM meteorologist James Thompson said a "humid air mass" was expected to accompany the heat, with Brisbane set to swelter through a sticky Christmas day.

The top of 33 degrees was higher than predicted earlier this week and four degrees above the monthly average. Brisbane has not reached 32 degrees on Christmas Day since 2005, when the city reached a peak of 33.4 degrees.
