Weather in September
Temperature
With the onset of September, Devine experiences a modest temperature adjustment, with the average high-temperature gently receding from a torrid 97.3°F (36.3°C) in August to a hot 90.1°F (32.3°C). Devine, in September, experiences an average temperature of 72.1°F (22.3°C) at night.Heat index
In September, the average heat index is computed to be a scorching 104°F (40°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Heat index details are generally centered around shaded locations and a mild breeze. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
