What's the weather going to do on Christmas Day?

ONE week out from Christmas Day, and we've now got an idea of the forecast and there is cause for celebration.

By the looks of it, you can start cementing those plans for a beach or backyard barbecue.

Bureau of Meteorology forecaster Craig Ryan said the weather leading up to Christmas would be warm and could potentially continue for the big day.

"It's expected mostly sunny conditions over next few days but a change is coming through on Wednesday or Thursday where we will see a bit of rainfall and a slight drop in temperature,” Mr Ryan said.

"At this stage rainfall will be about 8-10mm along the coast, but we may see larger totals inland.”

But he said any rain will clear early on in the weekend, followed by hot and sunny conditions on Christmas Eve, where temperatures will sit "in the low to mid 30s”.

Christmas Eve looks to be a warm one for Lismore with a top of 34C and Casino with a top of 36C and sunny conditions.

Along the coast will be a few degrees cooler on Sunday where temperatures will top 31C for Ballina and Byron Bay.

Before then temperatures will soar as a severe heatwave sweeps the Northern Rivers today and tomorrow.

Temperatures will reach 34C tomorrow and 35C Wednesday in Lismore, but will sit in the low 30s along the coast.

It will drop to low-intensity after Wednesday where things will cool slightly and bring a dusting of rain before a sunny weekend.
