Sumner Bar Surf and Wind Quality by Month (Canterbury, New Zealand)

The charts below show frequency of occurrence of a certain swell or wind in Sumner Bar, broken down by both direction and strength (wave height).

IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.

You can also compare this with Sumner Bar swell conditioned on favourable winds.

Also see overall Sumner Bar surf quality charts (on the guide page) and Sumner Bar surf quality by season.

FEATURE UPDATE: we now show red swell icons for 'open sea' swells that are travelling in an unfavourable direction for the surf break. In places, these swells may still wrap around coastlines and produce smaller waves at some breaks. They are also significant for windsurfers and other water users that tend to venture further off-shore.
