Weather in September
Temperature
A subtle change in temperatures is noted as August gives way to September, with average highs reducing from a sweltering 95.5°F (35.3°C) to a tropical 88.7°F (31.5°C). Navarro observes an average low-temperature of 69.6°F (20.9°C) during September nights.Heat index
For most parts of September, the heat index is calculated to be a torrid 100.4°F (38°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.Note that heat index values are valued for light wind and location in the shade. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
