Weather in September
Temperature
The commencement of September brings an average high-temperature of a still tropical 34.4°C (93.9°F), marking an inconsequential divergence from August. In September, the temperature drops to an average of 25.5°C (77.9°F) at night.Heat index
The heat index in September is computed to be a burning hot 48°C (118.4°F). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
