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.

FYFFE HOUSE
Robert Fyffe established Kaikoura's first shore whaling station and the home he built in 1842 is today known as Fyffe House. The house was built using native timbers with lath and plaster interior walls and mud and straw insulation. The house still rests on its original whalebone foundations. Fyffe House was bequeathed to the Historic Places Trust in 1981 and is the town's oldest building, remaining virtually unchanged from its whaling era origins.
