O‘ahu Community Heat Map

On August 31, 2019, the O‘ahu Community Heat Assessment, lead by the City & County of Honolulu Office of Climate Change, Sustainability & Resiliency and community volunteers, collected heat and humidity data across O‘ahu in one of the largest heat campaigns of the year. In early February 2020, the group released their results and promoted their story to local press.
