Weather in September
Temperature
Leroy starts September with an average high-temperature of a still tropical 88.5°F (31.4°C), a minor shift from August's 92.1°F (33.4°C). Throughout the month of September, Leroy observes an average nighttime temperature of 68°F (20°C).Heat index
The average heat index in September is appraised at a blisteringly hot 104°F (40°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
