Because much of the Marlborough region is sheltered by high country to the west, south and in some areas to the
east, it is New Zealand's sunniest region.
Warm, dry and settled weather predominates during summer. Winter days often start with a frost, but are usually
mild overall. Typical summer daytime maximum air temperatures range from 20°C to 26°C, but occasionally rise above
30°C. Late winter and early spring is normally the most unsettled time of the year.
Typical winter daytime maximum air temperatures range from 10°C to 15°C. Annual hours of sunshine average at least
2,400 hours. High temperatures are frequent in Blenheim and may be accompanied by föhn winds from the northwest,
characterised by the distinctive "wave" cloud formations.
