Weather in September
Temperature
Frontera Echeverría's average high-temperature in September is a still hot 32.6°C (90.7°F), indicating a subtle variation from August. During September, an average low-temperature of 21.5°C (70.7°F) is observed.Heat index
The heat index in September is calculated to be a burning hot 48°C (118.4°F). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.Always consider that heat index estimations are for light winds and places in the shade. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
