Heat index

During September, the heat index is evaluated at a blisteringly hot 105.8°F (41°C). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Humidity

The months with the highest humidity are August and September, with an average relative humidity of 79%.

Note: The daily high UV index of 7 in September translates into this advice:
Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. The Sun's UV radiation is most potent between the hours of 10 a.m. and 4 p.m. Try to avoid direct sunlight during this time. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
