Weather in September
Temperature
The arrival of September suggests a slight decrease in the average high-temperature, moving from a very hot 95.5°F (35.3°C) in August to a hot 89.1°F (31.7°C). Montgomery experiences a steady low-temperature of 70.2°F (21.2°C) throughout September.Heat index
The heat index for September is calculated to be an extremely hot 105.8°F (41°C). Undertake additional safety actions, risk of heat cramps and heat exhaustion is significant. Persistent activity may induce heatstroke.Know that the heat index computations account for shaded terrains and slight winds. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. 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. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
