Weather in September
Temperature
September notes an average high-temperature of a hot 30.3°C (86.5°F), subtly differing from August's 29.4°C (84.9°F). September nights in Libertad are marked by an average temperature drop to an enjoyable 19.8°C (67.6°F).Heat index
September's heat index is appraised at a very hot 35°C (95°F). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

May through December, with an average maximum UV index of 6, are months with the lowest UV index. A UV Index estimate of 6 to 7 represents a high health risk from unprotected exposure to Sun's UV rays for ordinary individuals.Note: The UV index of 6 in September translates into these instructions:
Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. A wide-brimmed hat provides unparalleled sun protection for sensitive areas like the eyes, ears, and neck.
