Miami ties all-time temperature record at 100°F

In August 2026, Miami, Florida, reached 100 degrees Fahrenheit, tying its all-time record set in 1942. This rare occurrence was due to a powerful heat dome affecting the region, which typically prevents such high temperatures due to its coastal location and humid climate. The National Weather Service noted that this reading was significantly above the average high for mid-August, prompting health advisories for residents.
