Weather in September
Temperature
A mild drop in Elmo's average high-temperature is observed in September, transitioning from a very hot 95°F (35°C) in August to a tropical 87.8°F (31°C). An average low-temperature of 68.9°F (20.5°C) is observed during September nights.Heat index
The heat index in September is appraised at a torrid 96.8°F (36°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.Consider that heat index readings are for situations in the shade and light wind. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
