Temperature

The average high-temperature during September is a very hot 35.9°C (96.6°F), almost matching the conditions of the preceding month. Throughout September, Fatao witnesses a consistent average low-temperature of 26.3°C (79.3°F).

Heat index

During September, the heat index is computed to be a blazing hot 45°C (113°F). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Take the necessary steps to protect yourself; unprotected skin and eyes are vulnerable to damage. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
