Weather in September
Temperature
As September commences, the average high-temperature subtly reduces, transitioning from a tropical 94.6°F (34.8°C) in August to a still hot 88.7°F (31.5°C). Nighttime temperatures hover around an average low of 68°F (20°C) in September.Heat index
The heat index in September is evaluated at a blistering 104°F (40°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.In terms of the heat index, values are set with light wind and shade conditions in mind. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its 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. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
