Temperature

Heat index

July's heat index is estimated at a blisteringly hot 105.8°F (41°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
Remember that heat index calculations are made for conditions in the shade with light wind. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. 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.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
