South Florida could break a hot temperature record on Friday.

Forecasters are calling for a high of 95 in the early afternoon. If the mercury hits that mark, it will break a record set on this date on June 16, 2011, according to National Oceanic and Atmospheric Administration’s climatological daily records.

The record low for this day, by comparison, was 80 degrees on June 16, 1984.

Ah, for the 80s!

Heat advisory

South Florida remains under a heat advisory until 7 p.m. Friday. The advisory was issued and extended on Wednesday, the first time the National Weather Service in Miami used its new lower threshold that forecasters and Miami-Dade officials approved in May.

Even with an aerator working hard to cool off the waters of the University of Miami’s competitive 50-meter outdoor pool, a high heat index and temperatures in the 90s made it hard to beat the heat on June 15, 2023.
