Weather in September
Temperature
The move into September indicates a slight reduction in the average high-temperature, down from August's fiery hot 96.1°F (35.6°C) to a hot 87.6°F (30.9°C). Throughout the month of September, Richland Hills witnesses an average temperature of 70°F (21.1°C).Heat index
During September, the heat index is calculated to be a very hot 95°F (35°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.Data suggests that the heat index is set for environments in shade and with a light wind. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
