September proves to be the warmest month, recording an average peak temperature of 31.5°C (88.7°F) and a minimum temperature of 16.2°C (61.2°F).

Heat index

September's heat index is appraised at a very hot 35°C (95°F). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', shows a temperature sensation when both heat and moisture conditions are combined. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
