A cold front moves north over the country on Monday, delivering cooler temperatures and showers to parts of the South Island and lower North Island. Behind it, a ridge of high-pressure builds, leading to several days of settled weather.

The cold front will also generate hazardous marine conditions, with large, long-period southerly swells affecting the eastern coastlines from Otago to Gisborne. Long-period swells carry more energy, allowing waves to travel further inland and surge higher up beaches than usual. These conditions may cause significant coastal impacts, including ferry cancellations, road closures, and, in some locations, evacuations. People in affected areas should follow advice from local authorities.

Heavy Swell Warnings are in place until mid-Wednesday.

Hazardous swells set to impact eastern New Zealand early this week.

A powerful southerly swell is expected to affect eastern coastlines from Otago to Gisborne through to midweek, bringing large waves and dangerous coastal conditions.

These long-period swells carry significant energy, allowing waves to surge further up beaches, over coastal roads, and into low-lying coastal areas than usual.

Potential impacts include:
⚠️ Dangerous conditions near the coast
⚠️ Coastal inundation and wave overtopping
⚠️ Ferry disruptions and transport delays
⚠️ Local Road closures in vulnerable areas

If you're heading to the coast, stay well back from the water's edge and keep up to date with advice from local authorities and the latest Heavy Swell Warnings at www.metservice.com/warnings.
