Weather in September
Temperature
The onset of September notes an average high-temperature of a still warm 29.3°C (84.7°F), subtly shifted from August's 29.7°C (85.5°F). Nighttime readings in Dufort during September register a minimal drop from daytime highs, averaging at a still warm 25.3°C (77.5°F).Heat index
Throughout September, the heat index is evaluated at a sweltering 35°C (95°F). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.In the scope of the heat index, its values resonate with shade and light wind conditions. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. 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 remain especially vital for babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
