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.

It's a Fact...
TO EAT CRAYFISH
The seaside township of Kaikoura takes its name from the legend of the mythical warrior Tamatea-Pokai-Whenua who, while chasing some of his runaway wives, stopped along the way to make a meal of crayfish. Although the township's name means "to eat crayfish", it is said that its full name is Te Ahi-kai-koura-a-Tamatea-pokai-whenua, meaning "the fire which Tamatea-Pokai-Whenua made to cook crayfish".
