Temperature

September's arrival shows an average high-temperature of a still hot 30.1°C (86.2°F), echoing the conditions of August. During September, Cuyab's temperature falls to a steady low-temperature average of 24.8°C (76.6°F).

Heat index

September's mean heat index is computed to be a very hot 39°C (102.2°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are largely significant for babies and toddlers. 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.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Note: In September, the average maximum UV index of 7 translates into the following recommendations:
Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
