Printable Heat Index Chart

I just found this amazing chart that I have to share with you all! It’s a heat index chart and it’s seriously going to save your life this summer. No more guessing when it’s too hot to be outside, just pull up this bad boy and you’ll know exactly what you’re dealing with.

How to Read the Chart

The chart is pretty straightforward, but I’ll break it down for you just in case. The top row is the temperature in degrees Fahrenheit, and the left column is the relative humidity percentage. The numbers in the chart are the heat index (feels like temperature) based on those two factors.

For example, if it’s 90 degrees Fahrenheit and 60% humidity, the heat index is 100. That means it feels like 100 degrees outside even though the actual temperature is only 90.

Why the Heat Index Matters

Knowing the heat index is important because it helps you understand how your body is going to react to the heat. When it’s hot and humid, your body has a harder time cooling down because sweat doesn’t evaporate as quickly. This can lead to heat exhaustion or even heat stroke if you’re not careful.

So, for your own safety, it’s a good idea to avoid being outside when the heat index is above 90. If you do have to be outside, make sure you stay hydrated and take breaks in the shade or air conditioning as often as possible.

Some Other Tips for Staying Cool

Now that you know how to read the heat index chart, here are a few other tips for staying cool this summer:

• Drink plenty of water, even if you don’t feel thirsty
• Avoid alcohol and caffeinated drinks, which can dehydrate you
• Wear loose, light-colored clothing
• Stay in air-conditioned buildings as much as possible
• Use fans to help circulate air
• Take cool showers or baths to lower your body temperature
• Avoid strenuous activity during the hottest parts of the day

Final Thoughts

It’s really easy to underestimate the dangers of hot and humid weather, but it’s important to take it seriously. With this heat index chart and a few simple tips, you can stay safe and comfortable all summer long.

Just promise me you won’t be one of those people who says “but it’s a dry heat!” Trust me, 100 degrees is still 100 degrees, whether there’s humidity or not. Stay cool out there!
