September weather forecast
Nouna, Burkina Faso

As Nouna transitions from August to September, rainfall begins to ease, reducing significantly down to 37mm (1.46"). The wet season starts to show signs of wrapping up, as relative humidity decreases and cloud cover begins to recede. Despite the decline in rainfall, the prevailing temperatures remain relatively cool, a respite from the warmer months at the year's start. Sunshine returns to the forefront, providing warmth and brightness to the dissipating rains. September thus marks the onset of the transition period before the dry season kicks in again.

Temperature

With the advent of September, Nouna's high-temperatures adjust to a very hot 35°C (95°F), closely aligning with the preceding month. An average low-temperature of 24.9°C (76.8°F) is observed during September nights in Nouna.

Heat index

September's average heat index is evaluated at a burning hot 45°C (113°F). Prudent: Heat cramps and heat exhaustion are likely. Heatstroke becomes imminent with sustained exertion.
Heat index data is primarily for areas with shade and subjected to light winds. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.

Boost your sun resistance with garments that are densely woven yet spacious.
