Buma, Sierra Leone

Temperature

September's presence marks an average high-temperature of a still moderately hot 28.4°C (83.1°F), subtly varied from August's 27°C (80.6°F). Buma's temperature in September lowers to a consistent average of 21.5°C (70.7°F) during the nights.

Heat index

September's heat index is appraised at a very hot 35°C (95°F). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. The Sun's UV radiation is most intense from 10 a.m. to 4 p.m. Try to avoid direct sun exposure during these hours. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
