October weather forecast
Kayes, Mali

October welcomes the dry season back to Kayes, reflected in the meagre 8mm (0.31") of cumulative rainfall. The shift from September to October witnesses a decrease in temperature and relative humidity. On the positive side, sunny days increase, allowing for longer daylight hours. Consequently, the UV index starts its ascent back towards the annual average. This month embodies a marked change in weather, initiating the downward curve of rainfall for the upcoming months.

Temperature

October comes with a subtle rise, with the average high-temperature adjusting from a hot 34.8°C (94.6°F) in September to a very hot 38.2°C (100.8°F). Kayes's nighttime temperatures in October reflect a stark contrast to the day's highs, falling to an average low of 26°C (78.8°F).

Heat index

The heat index in October is evaluated at a burning hot 45°C (113°F). Stay vigilant: Heat cramps along with heat exhaustion are expected. Heatstroke may follow prolonged exertion.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

Be proactive in protecting yourself; skin and eyes can be harmed if left unprotected. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes.
