How windy is Christchurch in summer?
Windfinder’s Christchurch International Airport station averages 10.8 knots in December and January and 10.2 in February, from the east-north-east to east. That is a whole-day average; in June it falls to 6.7 knots.
On the estuary the north-easterly is the predominant wind, usually 12 to 18 knots and sometimes up to 25. The local windsurf guide calls the easterly sea breeze “by far the best”. North-westerlies blow now and then in summer; southerlies are more a winter wind.
Where can you kitesurf in Christchurch?
| Spot | Water | Level |
|---|---|---|
| Avon-Heathcote Estuary | Flat and shallow, about 3 hours either side of high tide | Beginners |
| South Brighton and the ocean beaches | Choppy, small to medium waves | Intermediate |
| Sumner Bar | Undertow that runs south | Intermediate |
The estuary is the place to learn and the busiest water in town. On a good summer day the windsurf guide counts more than 500 windsurfers, sharing the water with three yacht clubs, so follow the right-of-way sign at the windsurf park.
The ocean beaches, such as South Brighton, have waves when you want more than flat water, and they suit surfing too. They are patrolled at weekends and in school holidays.
What should you watch out for?
- Tides: the estuary turns too shallow outside the three hours either side of high tide.
- Crowds and sailing boats on the estuary in summer.
- The ocean beaches are known for potholes and rips.
- At Sumner, an undertow carries you sideways to the south.
The beach details come from an older, undated windsurf guide, so check conditions locally. For another South Island sea-breeze beach, see Nelson.
