New report confirms 2025 among Hawai'i's driest, warmest on record

In 2025, Hawaiʻi experienced its second-driest year in more than a century, alongside persistently above-average temperatures throughout the year—a stark reality detailed in the inaugural Hawai'i Annual Climate Report 2025. Published by the University of Hawai'i Sea Grant College Program, this first-of-its-kind report uses plain language, along with easy-to-interpret maps and figures, to summarize statewide rainfall, temperature, and drought conditions over the past year.
