September's climate shows a minor adjustment in average high-temperatures to a still tropical 30.2°C (86.4°F) from August's 31.3°C (88.3°F). Tango notes a substantial temperature decline from the daytime peaks throughout September, with an average nighttime temperature of 18°C (64.4°F).

Heat index

For September, the heat index is computed to be a very hot 36°C (96.8°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.
The standards for the heat index are set for locations in shade and under light breezes. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
