Summer took a short break yesterday morning, when some areas of Central Otago received a touch of frost.
MetService meteorologist Cameron Coutts said it was due to a cold air mass that moved across the country after the passage of a cold front.
He said many places in Central Otago had minimum air temperatures as low as 2degC-3degC yesterday morning and minimum grass temperatures in some areas were below zero.
''Oamaru and Tara Hills both had light frosts.
''Tekapo got down to 0.4 degrees and Alexandra got down to 2.6 degrees and anywhere higher than Alexandra could have had frosts,'' Mr Coutts said.
On average, Queenstown had two days of frosts in December ''but these averages are weighted towards temps from the previous century, when the climate was slightly colder, and the climate is gradually warming now,'' he said.
The forecast for today is for a return to summer weather, morning temperatures set to be much warmer because of a high moving in with light winds and no cloud.
