Heat index

For September, the heat index is computed to be an extremely hot 104°F (40°C). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

The average relative humidity in September is 74%.

Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
