Weather in September
Temperature
The commencement of September brings an average high-temperature of a still tropical 30.4°C (86.7°F), marking an inconsequential divergence from August. Throughout September, Prepedan's nights experience a slight temperature dip to a warm 25.6°C (78.1°F).Heat index
The heat index value during September is computed to be a sweltering 36°C (96.8°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
