Heat index

September's heat index is appraised at a blazing hot 45°C (113°F). Stay alert: Heat cramps and heat exhaustion are expected. Heatstroke is a likely outcome of ongoing activity.
Understanding the heat index involves considering values for shaded locales with light wind. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
