Weather in September
Temperature
An average high-temperature of a still tropical 30.4°C (86.7°F) marks September, exhibiting a close resemblance to the conditions in August. September in Sierra Morena sees the temperature falling to a mean low of 25.2°C (77.4°F).Heat index
September's mean heat index is calculated to be a fiery hot 39°C (102.2°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.

Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
