Weather in September
Temperature
Nueva Esparta registers an average high-temperature of a still hot 31.7°C (89.1°F) at the commencement of September, closely related to the preceding month. Throughout September, the average low-temperature records at an agreeable 22.1°C (71.8°F).Heat index
Throughout September, the heat index is appraised at a blistering 44°C (111.2°F). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
