The introduction of September sees an average high-temperature of a still moderately hot 28.4°C (83.1°F), hardly deviating from August. Salay notes a consistent average low-temperature of 23.7°C (74.7°F) during September nights.Heat index
September's average heat index is computed to be a hot 33°C (91.4°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. 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', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
