September weather forecast
Eteke, Gabon

In September, Eteke records a significant hike in rainfall compared to August, as conditions start hinting at the incoming wet season. Despite the rise in precipitation, temperatures stay within a fairly consistent range, not deviating much from August figures. In terms of sun exposure, September sees shorter sunshine hours owing to more cloud coverage. The wind speeds in September stay relatively low, showing a slight decrease from August. As we move towards October, weather conditions begin to display an uptrend in rainfall, heralding the start of a new wet season.

Temperature

The introduction of September notes a subtle temperature variation to a still hot 30.5°C (86.9°F) from August's 31.4°C (88.5°F). An average temperature of 21.5°C (70.7°F) marks the nights in September.

Heat index

The average heat index in September is estimated at a sweltering 39°C (102.2°F). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.
Observations indicate that the heat index values are for shady locations with light wind. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Humidity

In Eteke, the average relative humidity in September is 78%.

Note: In September, the maximum UV index of 6 suggests this advice:
Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
