Samoa is adopting a new weather and climate prediction model, saying climate change is making historical data irrelevant.
The Meteorological Service's principal scientific officer, Tile Tofaeono, said weather predictions have always been dependent on data about historical weather patterns.
Mr Tofaeono said the statistical method has worked well, but with climate change, nothing makes sense anymore.
Samoa is transitioning to a new model being introduced by the South Korea-based APEC Climate Centre, which relies on advanced mathematics gathered from state-of-the-art watchers around the world.
