Temperature

The start of September sees the average high-temperature at a still tropical 31°C (87.8°F), showing little difference from August's 31.3°C (88.3°F). Char Alexander in September observes a slight diminution in temperature from daily highs, recording a low-temperature average of 26.7°C (80.1°F).

Heat index

In September, the average heat index is calculated to be an extremely hot 41°C (105.8°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are quite important for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Humidity

The average relative humidity in September in Char Alexander is 80%.

Note: The daily high UV index of 7 in September translates into this advice:
Continue precautions and advocate sun safety advice. Deterrence of sunburn is indispensable. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
