Weather in September
Temperature
The arrival of September suggests a slight decrease in the average high-temperature, moving from a sweltering 95.5°F (35.3°C) in August to a hot 88.7°F (31.5°C). During September, the nighttime temperature in Richland averages of 69.6°F (20.9°C).Heat index
The average heat index in September is estimated at a very hot 100.4°F (38°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.The standards for the heat index are set for locations in shade and under light 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 'real feel' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. As body temperatures escalate without effective heat release, one might face dehydration threats.
