Introduction to the Heat Wave
Wednesday is forecast to be the hottest day of the year so far, as South Florida looks at high temperatures reaching into the low-90 degrees.
Normal for this time of year is to have high temps in the upper-80s.
Current Temperature Records
So far, the hottest it’s been is 91 degrees, which we’ve hit twice this month, on the 14th and 17th .
Wednesday our area is to hit 93 to 94 degrees. The final temperature will be determined by whether the winds can shift from the south to the west Wednesday afternoon fast enough for us to get much warmer than the low 90s.
Historical Temperature Records
The current record for this date is 95 degrees in Miami and 96 degrees in Fort Lauderdale. Both of these records were hit back in 2008.
Heat Safety Awareness
As we continue observing Heat Safety Week, #MDFR reminds you that certain populations are more vulnerable to the effects of extreme heat.

Heat Index and Expected Conditions
Regardless if we hit the record high temp, the feel-like conditions will be into the triple digits.
We could have heat index values near 105–but not for the duration needed for heat alerts. To hit that criteria, we’d need to stay at 105 for two or more hours.
But, it will be the hottest we’ve felt as temperatures climb near record highs.
Managing the Heat
The heat will impact those working outdoors for extended periods of time along with anyone that is sensitive to the heat. Taking breaks in the air conditioning and drinking lots of water or electrolytes will help manage the heat impacts on our bodies.
After Wednesday, rain chance increase, and this will help break up some of the extreme heat.
Conclusion
In conclusion, Wednesday is expected to be the hottest day of the year so far, with temperatures reaching into the low-90s. It is essential to take necessary precautions to manage the heat, especially for vulnerable populations. Stay safe and stay informed.
