Weather in September
Temperature
September's onset introduces a mild reduction in the average high-temperature, from a hot 94.1°F (34.5°C) in August to a still tropical 88.3°F (31.3°C). Throughout September, an average nighttime temperature of 66.9°F (19.4°C) is experienced.Heat index
September's mean heat index is appraised at a fiery hot 102.2°F (39°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.Realize that the values for the heat index are set for shaded places and light winds. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
