Temperature

Esiẹ experiences a transition to a still warm 28.5°C (83.3°F) in average high-temperatures with the arrival of September, not greatly differing from August's 27.8°C (82°F). In September, the average low-temperature is a pleasant 21.2°C (70.2°F).

Heat index

September's average heat index is evaluated at a very hot 35°C (95°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. 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 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
