Why It Matters

Elevated nighttime temperatures prevent the body from recovering from daytime heat exposure, which increases the health risk for residents without adequate air conditioning.

Key Facts

  • Summer nights in Florida are warming nearly twice as fast as summer days.
  • Heat index values are forecast to potentially exceed 105 degrees Fahrenheit next week.
  • High-pressure systems are expected to cause extreme heat across much of Florida, including Miami, through next weekend.
  • Record high minimum temperatures are possible due to a lack of overnight cooling.
  • Consecutive hot nights prevent the body from recovering from daytime heat exposure.
  • Residents without adequate air conditioning are at higher risk during periods of sustained overnight heat.
