Weather in September
Temperature
September heralds a minor drop in average high-temperature, sliding from August's sweltering 95.5°F (35.3°C) to a hot 88.7°F (31.5°C). Throughout the month of September, Bryan sees a steady low-temperature average of 70.3°F (21.3°C).Heat index
September's heat index is estimated at a fiery hot 102.2°F (39°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Heat index's context suggests values are appropriate for shady areas and slight breezes. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. 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 are extremely significant for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
