KEVIN STENT/Stuff The Bluebridge ferry struggles out of the harbour entrance last April. Tomorrow’s waves are forecast to be bigger. (file photo) South coast communities – including Ōwhiro Bay, badly damaged by waves in April last year – would face the worst of the swells. Some coastal areas in Wellington Harbour, such as Eastbourne and Petone, would also see big waves. Tuesday’s waves are forecast to be bigger than those in April 2020, which required evacuations in some coast suburbs. MetService has issued a heavy-swell warning for the south coast that starts at 6am on Tuesday and ends 41 hours later, at 11pm on Wednesday.
