Weather in September
Temperature
September brings an average high-temperature of a still hot 30.8°C (87.4°F), showing a slight difference from August's 31.6°C (88.9°F). El Junco's temperature in September lowers to a consistent average of 25.6°C (78.1°F) during the nights.Heat index
For September, the heat index is calculated to be a scorching 40°C (104°F). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', gives an indication of how one might feel in terms of heat after considering humidity. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

The months with the highest UV index are March through October, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health vulnerability from unprotected exposure to Sun's UV rays for the ordinary person.Note: The UV index of 7 in September translates into these instructions:
Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear.
