Heavy and prolonged rain a fortnight ago, followed by strong southerly winds, uprooted numerous trees, making the area and its tracks unsafe for public use.
''In these conditions, trees are highly vulnerable to wind-throw due to their root anchorage being compromised.
Approximately six pockets of trees have blown over along the walking tracks, with other trees damaged or leaning dangerously, creating hazardous conditions,'' Waitaki District Council recreation manager Erik van der Spek said.
A range of work would be required to make the area safe again for public use, including felling unstable and leaning trees, cutting up fallen trees and clearing debris off tracks.
''Consideration will also be given to the option of felling a larger area of trees that are now vulnerable to further damage from strong winds in the future,'' he said.
Signs and ''Danger: Keep Out'' tape had been put up at entrances.
While the cape was closed, alternative locations for dog-exercising included Fenwick Park, the rail corridor between Saleyards Rd and Weston and coastal areas between Oamaru and Kakanui.
''We realise this is disappointing for users of the cape, which is a hugely popular recreational destination, and apologise for the closure. We will keep the public posted on when we will be reopening this area,'' he said.
