About SwellMap

With SwellMap you know you're getting quality forecast information.

The system was developed by MetOcean Solutions, who provide high tolerance weather data to the offshore and marine industry in New Zealand and overseas.

SwellMap uses the latest atmospheric and oceanographic numerical models, and a large computing facility, to produce forecasts which are updated 4 times per day.

All the weather information is made in New Zealand and is presented without human interpretation.

New Zealand is a unique place for weather - the variability and complexity we experience daily means that our population is very aware of the weather outcomes. We must have a higher percentage of 'weather experts' per capita than any other country. Everyone knows that the weather can be very different only 20 km down the road, and that's why WeatherMap provides forecasts at a resolution of 6 to 18 km. This allows us to predict the weather at many of the smaller towns in New Zealand, as well as splitting our bigger cities into smaller weather (and activity) areas.
