HEAVY SWELL WARNING – Wellington South Coast and Wairarapa Coast
Issued: 1.00pm - 28 June 2021
What is happening?
Heavy swells, rising to 6 meters, are expected along Wellington’s South Coast and the Wairarapa Coast between Tuesday evening and Wednesday morning. We expect to see the biggest impacts of these swells coinciding with the high tides that are due around 8:57pm on Tuesday 29 June and 9.22am on Wednesday 30 June.
Although the largest waves are expected between Tuesday evening and Wednesday morning, it is expected that the waves will start building from Tuesday morning. Swell heights of 6 metres are similar to what was experienced on Wellington’s South Coast on 15 April last year.

Hazardous swell and surf and coastal flood warning is issued for:
The WELLINGTON SOUTH COAST area including: Owhiro Bay, Island Bay, Houghton Bay, Lyall Bay, Moa Point, Reef, Flax, Eve and Breaker Bays, Seatoun and Karaka Bays.
Large waves are expected in the inner harbour area, Petone and Eastbourne however the impacts are not expected to be as significant as that for the South Coast. The
