Extreme Heat Frequently Asked Questions (FAQ's)

When does heat become dangerous in Florida?

Florida is naturally a hot location.  It is not uncommon for us to experience temperatures in the mid-to-high 90's during our summers.  However, it is rare for us to exceed 100°F in Tallahassee.  The actual air temperature isn't the only concern.  When you add high humidity levels into the equation, we get Heat Index temperatures that make it feel like 108°F or more.  That's when things get real dangerous. 

How hot does it get in Tallahassee?

Tallahassee, on average, will start to break 90°F for daily high temperatures by late-May or early-June and stay there until mid-to-late September.  It is quite normal to see daily high temperatures up to about 95-98 degrees.  When we start to push 100°F, then we're in for a "real hot" day by local standards.  The all-time record high in Tallahassee is 105°F. 

How often does Tallahasseee see extreme temperatures?

While Heat Advisories can occur almost every year during the summer, we average an Excessive Heat Warning about once every 3-5 years. 

What does Heat Index mean? How can it feel hotter than it actually is?

As if the actual air temperature doesn't get hot enough by itself, the effect of adding humidity into the mix makes it feel a whole lot hotter on the human skin.  We will often refer to this as the "feels like" or "apparent temperature."  The higher humidity levels, the hotter it feels above actual air temperature.  Learn More>>

What are the hazards of excessive heat?

During extremely hot and humid weather the body's ability to cool itself is affected. When the body heats too rapidly to cool itself properly, or when too much fluid or salt is lost through dehydration or sweating, body temperature rises and heat-related illnesses, including dehydration and hyperthermia may develop.

Who is most at risk for heat-related illness?

Infants and children up to four years of age; people 65 years of age or older; people who are overweight; people who overexert during work or exercise; people who are ill or on certain medications. Don't forget pets which are unacclimated to outdoor weather.

Can leaving a child or pet in a parked vehicle be deadly?

Absolutely! Each year, dozens of children and untold numbers of pets left in parked vehicles die from hyperthermia. Hyperthermia is an acute condition that occurs when the body absorbs more heat than it can handle. Hyperthermia can occur even on a mild day. Studies have shown that the temperature inside a parked vehicle can rapidly rise to a dangerous level for children, pets and even adults. Leaving the windows slightly open does not significantly decrease the heating rate. The effects can be more severe on children because their bodies warm at a faster rate than adults. Learn More>>
