Central Otago is a land of extremes: it is the coldest, driest part of New Zealand. The seasons are sharply defined: summers are hot and low in humidity; winter mornings are often misty, the days cloudless and windless and the nights freezing. Alexandra, for example, has the lowest average annual rainfall (340mm) recorded anywhere in New Zealand, is the least windy and has 148 frosts annually (only Lake Tekapo, with 149, has more). Ophir, 27 km away, holds the record for the lowest air temperature recorded - minus 21.6 deg C in mid-1995 - but it also held the highest reading (35.2 deg C in 1959) until 42.4 deg C was recorded at Rangiora, in Canterbury in 1973.
Spring warms the soil and fruit tree blossom dominates the district�s orchard areas. Temperatures range from minus 3 to 20 deg C, with 10 frosts a month. Average rainfall is 28mm a month and sunshine 206 hours.
In summer, daylight lasts as long as 10pm. Temperatures range from 10 to plus 30 deg C on several days. Rainfall averages 38mm a month and sunshine is 227 hours.
Autumn is brilliant as the extensive orchards and poplar shelterbelts turn red, yellow and gold. Temperatures range from minus 3 to 24 deg C. Rainfall averages 30mm a month with 11 frosts monthly and 150 hours of sunshine.
Winter brings a temperature range of minus 6 to 15 deg C, and average monthly rainfall of 15mm, 25 days frosts and 107 hours of sunshine per month during the short days
