Heat index

In August, the heat index is estimated at a very hot 95°F (35°C). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
Heat index evaluations are typically in the context of light winds and shaded environments. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
