Heat index

For September, the heat index is computed to be a blisteringly hot 43°C (109.4°F). Vigilance: Heat cramps and heat exhaustion are likely. The likelihood of heatstroke increases with continued activity.
Bear in mind that the heat index values are determined for shaded areas and light breezes. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. 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. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.

The average relative humidity in September is 72%.

Remember, devices such as parasols or canopies might not provide complete sun protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
