Be sure to check this heat index chart before you head out in the heat of summer, because when the temperature is high and accompanied by high humidity, it can feel a lot warmer than the thermometer indicates.
The combination of high temperature and high humidity reduces your body's ability to cool itself. For example, the heat you feel when the actual temperature is 90ºF with a relative humidity of 70% is 106ºF. When the heat index is high, drink plenty of water and spend the midday hours someplace cool!
As the days begin to shorten,
the heat begins to scorch them.
–Weather proverb
