Why it matters

Heat-related deaths remain a persistent public health issue in Maricopa County, even as the county has seen declines in recent years. This first death of 2026 highlights the ongoing challenges the region faces in protecting vulnerable populations from extreme heat.

The details

  • An eight-day streak of triple-digit temperatures from March 18 to 25 produced the hottest March days ever recorded, with highs reaching 105 degrees on three consecutive days.
