Weather in September
Temperature
In September, the average high-temperature registers at a still tropical 31.6°C (88.9°F), nearly identical to August's 30.2°C (86.4°F). The low-temperature average for Modire during September stands at a pleasant 22.8°C (73°F).Heat index
September's mean heat index is calculated to be an extremely hot 41°C (105.8°F). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
