Weather in September
Temperature
In Cogo, September's average high-temperature stands at a still moderately hot 27°C (80.6°F), closely related to the preceding month. September's average low-temperature is a still warm 23.6°C (74.5°F), reflecting a minor difference from the day's peak temperatures.Heat index
The heat index for September is computed to be a hot 30°C (86°F). With prolonged exposure and constant activity, one might feel exhausted and experience heat cramps.Always consider that heat index estimations are for light winds and places in the shade. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. 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. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
