Temperature

The transition into September in Guinguineo notes an average high-temperature of a still hot 33.8°C (92.8°F), revealing a mild distinction from the 33.7°C (92.7°F) in August. An average temperature of 24.8°C (76.6°F) marks the nights in Guinguineo, Senegal, in September.

Heat index

Throughout September, the heat index is calculated to be a blazing hot 48°C (118.4°F). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'felt air temperature' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values remain especially vital for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Resist overexposure. Safeguarding from solar damage is indispensable. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
