Weather in September
Temperature
Southmont experiences a transition to a still tropical 87.1°F (30.6°C) in average high-temperatures with the arrival of September, not greatly differing from August's 90.9°F (32.7°C). Southmont records an average low of 67.3°F (19.6°C) throughout the nights in September.Heat index
The heat index value during September is estimated at a torrid 98.6°F (37°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
