Heat index

The heat index value during July is estimated at a blazing hot 114.8°F (46°C). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.
The metrics for the heat index are tailored for both shady environments and light winds. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', combines both the air temperature and the humidity level to give a perceived human temperature. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Prevent overexposure. Protection from the sun's harmful effects is needed. 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. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
