Modern Weather and Early-Warning Infrastructure

An expanded weather-observation network and restored upper-air observations have improved forecasting, aviation information, and severe-weather preparedness.

Public sources report the installation or upgrading of automatic weather stations across multiple islands and the restoration of the Rarotonga upper-air sounding station in 2026. Work is also progressing toward the Cook Islands’ first weather radar for Rarotonga through climate-finance support — confirm whether the radar is installed, commissioned, or still in delivery, and use the correct status.
