Orlando - Since 1980 dew points have been on the rise during the summer

The hottest weeks of the summer are often referred as the Dog Days. Legend has it that Sirius, the brightest star of in the sky (not the Sun), rises and sets as the same time as the Sun and the synchronization of these two stars make for some extra hot weeks. This celestial match usually occurs between July 3 and August 11.

Of course that is just a legend, but inevitably, Central Florida (and some parts of Central United Stated) has definitely started to feel the effects of summer and already registered the hottest temperatures of the year so far.

Dry air cools and warms faster, but moist air is able to maintain the heat through the day and night. Although sweat is a cooling process in our bodies, the added ‘extra’ moisture during the summer months makes it more difficult for our bodies to cool off. Not only making it very uncomfortable but it could also be deadly if the right precautions are not taken. Heat is the leading cause of weather-related deaths in the country, each year averaging about 600 fatalities.

In the last 35 years, statistics show that summers in Orlando have been getting hotter; therefore increasing moisture content. The combination of high temperatures and high moisture content, dew points, are often fatal if the right measures are not taken when doing summer activities.

The increase in temperatures signal to the increase in greenhouse gases. It more heat occurs, then an increase in water vapor does too. This leads to stickier conditions, higher dew point. Ultimate this could lead to higher death tolls.
