Image: MetServiceA balmy Dunedin November is set to turn into a sweltering start to summer, with temperatures expected to reach the high 20s this weekend. The same weather patterns that have brought a record run of 25degC-plus days to Cromwell have brought a run of six 20degC-plus days to Dunedin, which started on November 25. The run of hot weather was also heating up the ground, which made temperatures even warmer again. At Dunedin Airport the average temperature for November had been 13degC, which was 1.5degC higher than the average of 11.5degC. Dunedin's sweltering start to summer could be a sign of things to come, as Niwa is predicting La Nina will bring warmer than usual conditions across the South Island.
