Hamilton, Taupo, Rotorua
As this region is sheltered by high country to the south and east, it has less wind than many other parts of New Zealand. Being inland, a wide range of temperature is experienced. Warm, dry and settled weather predominates during summer. Typical summer daytime maximum air temperatures range from 21°C to 26°C, rarely exceeding 30°C. Winters are cool and this is normally the most unsettled time of the year. Typical winter daytime maximum air temperatures range from 10°C to 14°C.
