Weather in September
Temperature
The average high-temperature for September is a warm 85.1°F (29.5°C), closely aligning with the temperature of the preceding month. Alamo experiences an average low-temperature of 68.2°F (20.1°C) in the month of September.Heat index
September's heat index is evaluated at a sweltering 95°F (35°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
