Weather in September
Temperature
The commencement of September brings an average high-temperature of a still tropical 31.4°C (88.5°F), marking an inconsequential divergence from August. During September, Bula Atumba's temperature falls to a steady low-temperature average of 19.5°C (67.1°F).Heat index
For most parts of September, the heat index is estimated at a very hot 37°C (98.6°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Given the heat index, its values are aligned with shaded sites and gentle winds. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. 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 of high significance for children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
