Don't let today's cloudy skies fool you - tomorrow will be fine, dry and warm across Otago.
And there's even better news for the weekend, with Boxing Day temperatures expected to hit 30degC inland.
MetService meteorologist Peter Little said a ridge of high pressure was hovering over the Tasman Sea today, moving slowly towards New Zealand.
That high pressure system would bring increasingly fine, warm weather.
While a weak front would brush the southern coast later today bringing a short spell of bad weather, it would be gone by Christmas, Mr Little said.
Tomorrow's temperatures would stay in the low 20s across Otago, with light winds from the southwest hitting coastal regions, including Dunedin. No rain was predicted.
This weekend the weather would go up another notch, with high temperatures across Otago's inland areas and a top of 30degC expected in Wanaka.
While the light coastal breeze would moderate those temperatures in Dunedin, highs were still predicted to be in the low 20s throughout the weekend, he said.
