Weather in September
Temperature
The advent of September brings a subtle shift in temperature, with the average high moving from a sweltering 97.3°F (36.3°C) in August to a hot 90.7°F (32.6°C). During September, El Carro records an average temperature of 75°F (23.9°C) at night.Heat index
September's heat index is computed to be a blistering 107.6°F (42°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. 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.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. 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. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

Persist in precautions and follow sun safety policies. Keeping sunburn at bay is imperative. 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. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
