September weather forecast
Bita, French Guiana

September sees another major climatic shift, as Bita experiences the highest temperature of 33.7°C (92.7°F) for the year. Despite the heat, a drastic reduction in humidity makes the warmth more bearable. The wind speeds increase further, cooling down the warm afternoons. The amount of sunshine reaches its zenith due to lesser clouds in the sky. The smallest monthly rainfall of 21mm (0.83") for the year marks this as the driest month.

Temperature

A minimal variation is noted in Bita's average high-temperature at the onset of September, reaching a still tropical 33.7°C (92.7°F) from August's 32.3°C (90.1°F). Bita reports an average nighttime low-temperature of 21.8°C (71.2°F) in September.

Heat index

In September, the average heat index is evaluated at a burning hot 49°C (120.2°F). Take caution: Heat exhaustion and heat cramps are probable. Heatstroke may be imminent with ongoing effort.
Understand that the heat index values take into account shaded locations and mild winds. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Persist with safeguards and heed sun safety doctrines. Keeping sunburn at bay is of prime importance. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
