Miami has record-breaking heat. Will it continue into the Fourth of July weekend?

If it feels like it’s been extraordinarily hot outside, you’re right.

Tuesday’s high of 98 degrees, recorded at 1:52 p.m., broke a record in Miami-Dade County. The previous high had been 95 degrees set on June 30, 2015, according to the National Weather Service.

Monday tied for the hottest June 29 at 94 degrees, which was set in 1993.

The higher temperatures have led to higher heat index values, which measures what the temperature feels like when relative humidity is combined with the air temperature, according to the weather service.

Normally, the heat index at this time of year would be from 100 to 105. But South Florida is recording heat index values from 105 to 107, said National Weather Service Meteorologist Steven Ippoliti.

The increase is due to Sahara dust from North Africa in the atmosphere, causing fewer showers and thunderstorms, which naturally cool down the area, Ippoliti said.

Each year, hundreds of millions of tons of soil blow across the Atlantic Ocean from the Sahara Desert in northern Africa, according to NASA.

In Miami-Dade County, the National Weather Service forecast for Wednesday shows a heat index value of 103 and temperature highs near 91. There will also be a 30 percent chance of showers and thunderstorms.

Thursday will see the heat index at 102 and highs near 91 degrees with a 30 percent chance of showers and thunderstorms. Friday’s forecast is a high near 91 and a 10 percent chance of showers and thunderstorms.

Fourth of July weekend festivities may see rain as well. Saturday’s forecast calls for a high near 91 and a 40 percent chance of showers and thunderstorms after 2 p.m.

Sunday’s forecast is a 50 percent chance of showers and thunderstorms after 8 a.m. with a high near 90.

As temperatures rise, authorities are reminding residents to remember the dangers of heat stroke. On Monday, Miami-Dade Fire Rescue took a dog suffering from heat stroke to an animal hospital. The dog had to be supplied with a continuous flow of oxygen.

“Although the circumstances to this particular case are unclear, it is a good opportunity to remind pet owners that our four-legged friends can also suffer from heat strokes,” Fire Rescue said in a statement. “It is always recommended that pets are kept in cool, shady areas where they have access to water. We sure hope for a speedy recovery for this pup.”
