The arrival of September sees a recorded average high-temperature of a still hot 30.3°C (86.5°F), without divergence from the previous month's conditions. Nampicuan experiences an average low-temperature of 22.6°C (72.7°F) in month of September.

Heat index

September's average heat index is calculated to be a scorching 40°C (104°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Note: The maximum daily UV index of 7 in September converts into the following recommendations:
Guard against overexposure. Protection from sun-induced harm is essential. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
