Weather in September
Temperature
The shift from August to September coincides with a small decrease in the average high-temperature, down to a still tropical 31.2°C (88.2°F) from a hot 34.8°C (94.6°F). Throughout September, an average nighttime temperature of 21.2°C (70.2°F) is experienced.Heat index
September's heat index is calculated to be a fiery hot 37°C (98.6°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.It is essential to grasp that the heat index's numbers are for shade and light wind settings. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', gives an indication of how one might feel in terms of heat after considering humidity. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating 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.
