Weather in September
Temperature
With average high temperatures of 29.8°C (85.6°F) and lows of 19.8°C (67.6°F), September is the warmest month.Heat index
For most parts of September, the heat index is evaluated at a very hot 35°C (95°F). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.Research indicates the heat index considers values in shaded locales and with light winds. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

A UV Index estimate of 6 to 7 represents a high health hazard from unprotected exposure to Sun's UV rays for average individuals.Note: In September, the maximum UV index of 6 suggests this advice:
Take precautions against overexposure. Protection against sun damage is needed. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. Employ a wide-brim hat for potent defense against up to 50% of UV rays. Beware! Reflections from sand and water can intensify the Sun's UV radiation.
