Weather in September
Temperature
Macombe's weather in September indicates an average high-temperature of a still warm 29.3°C (84.7°F), nearly consistent with the 29.7°C (85.5°F) of August. Macombe, during September nights, witnesses an average temperature marginally cooler than its daytime highs, at a still warm 25.1°C (77.2°F).Heat index
For most parts of September, the heat index is computed to be a very hot 35°C (95°F). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
