Weather in September
Temperature
With September's arrival, Niamana's weather records an average high-temperature of a still moderately hot 28.7°C (83.7°F), marking little difference from August's 28°C (82.4°F). During September, Niamana's temperature falls to a steady low-temperature average of 20.5°C (68.9°F).Heat index
In September, the average heat index is evaluated at a fiery hot 35°C (95°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Observations indicate that the heat index values are for shady locations with light wind. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', binds temperature metrics with humidity values to give a sense of the actual warmth. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are highly critical to babies and toddlers. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.

A UV Index estimate of 6 to 7 represents a high threat to health from exposure to the Sun's UV rays for average individuals.Note: A maximum daily UV index of 6 during September morphs into the following directions:
Shun overexposure. Protection from sun ravages is indispensable. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
