Weather in September
Temperature
September marks a gentle change in average high-temperature, declining from August's hot 94.6°F (34.8°C) to a still tropical 88.3°F (31.3°C). During September, the nighttime temperature averages of 67.1°F (19.5°C).Heat index
The heat index for September is estimated at a very hot 100.4°F (38°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. 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 hold particular importance for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
