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.

RAINBOW'S FOOTPRINT
Tapuae-o-Uenuku is the highest peak in the northeast of the South Island. The name translates from Maori as "footprint of the rainbow". At 2,880 metres it dominates the Inland Kaikoura Range, rising high above the valleys of the Clarence and Awatere Rivers. The first European to sight the mountain was the explorer James Cook, who called it Mount Odin, but later nicknamed it "The Watcher" since his ship seemed to be visible from it at so many points along the coast.
