Fiji Revives Ancient Weather Wisdom to Predict Cyclones

When wild yam vines creep along the ground in July, Fijian farmer Marika Radua knows a hurricane is coming between November and April. If the vines shoot upward, the islands will likely stay safe.

For generations, Pacific islanders have used nature as their weather forecast. Bees acting strangely, bananas flowering at odd times, and green turtles nesting further inland all signal that a cyclone might be approaching.

Now, science is catching up to what grandparents have known for centuries. In 2024, Fiji's Meteorological Service announced it would officially integrate traditional environmental knowledge into its forecasting systems, calling the pairing "a total package."

The country joins Vanuatu, Tonga, Samoa, Niue, and the Solomon Islands in a groundbreaking project that treats ancient wisdom as valuable data. Vanuatu even launched an app called ClimateWatch where islanders can report natural warning signs they observe.

On Vanua Levu, Fiji's second largest island, Radua teaches farmers to watch for nature's subtle shifts beyond normal seasonal patterns. The farmer and climate resilience expert has compiled centuries of cultural wisdom into a seasonal calendar that helps growers know when and where to plant.

The timing couldn't be more critical. The Pacific Ocean spans thousands of islands, many too remote for expensive weather monitoring equipment. Gaps in meteorological data mean some communities might not receive official warnings in time.

"You're looking at the biggest ocean in the world," says Siosinamele Lui, climate traditional knowledge officer at the Pacific Regional Environment Programme. "You don't have monitoring equipment on every island."

Since 2016, Pacific islanders have been reporting early warning signs directly to the Pacific Meteorological Desk via calls, messages, and social media. Researchers are studying how these traditional indicators correlate with weather events before building them into official climate models.

The approach isn't instant. Scientists need years of data to match traditional indicators with modern forecasting. But for remote communities, observing the land around them provides crucial preparation time that satellite data might miss.

The Ripple Effect

This fusion of old and new is transforming how the world thinks about climate resilience. Countries that once dismissed traditional knowledge as folklore now recognize it as sophisticated environmental science passed down through stories, songs, and careful observation.

The project is helping farmers return to traditional agricultural methods too, planting multiple crops at different times instead of modern monoculture. This diversity makes communities more resilient while keeping them attuned to nature's warnings.

"It's not just about traditional knowledge, it's about living in harmony with nature," Radua says. As climate change accelerates extreme weather across the Pacific, that harmony might be exactly what saves lives.
