What is the Temperature Method in Ideal Conditions?
Apollo provides two options for generating hourly ratings:
- Feels Like
- Wet Bulb Globe Temperature (WBGT)
Here's additional information about each method.
The Feels Like method uses the Actual and Feels Like temperatures to generate hourly ratings. Feels Like temperature is the same as the heat index, which takes into consideration temperature and humidity and is calculated for shady areas.
One of the cons of using the Feels Like method for athletes is that measurements are taken in shady locations. If you are exposed to direct sunlight, the heat index value can be increased by up to 15 °F (9.44 °C).
Wet Bulb Globe Temperature (WBGT)
The WBGT is a quantitative measure of heat stress in direct sunlight, which encompasses factors such as temperature, humidity, wind speed, sun angle, and cloud cover (solar radiation). The WBGT is used by military agencies, OSHA, and many nations to manage workload in direct sunlight.
The WBGT method is a better tool for athletes to keep track of temperature conditions during the summer because of its increased accuracy when measuring conditions in direct sunlight.
