September weather forecast
Kouta Bouyya, Djibouti

As Kouta Bouyya enters September, the summer's intense heat starts to recede. A gradual drop in temperature and increase in rainfall mark the onset of autumn. Nevertheless, sunshine levels remain above average, balancing the effect of increased rainfall. Even though cyclonic activity increases around this time, causing the wind speed to drop, the overall pressure remains stable. It's a great time for travelers as they can enjoy the beauty of the city without the intense heat of the previous months.

Temperature

As September takes hold, the average high-temperature is a still torrid 35.6°C (96.1°F), nearly mirroring that of the previous month. Kouta Bouyya observes an average nighttime low-temperature of 30°C (86°F) during the month of September.

Heat index

The heat index for September is appraised at a blisteringly hot 44°C (111.2°F). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
