Weather in September
Temperature
The shift into September uncovers an average high-temperature of a still tropical 88°F (31.1°C), subtly different from the previous month. Throughout September, the average low-temperature dips to a moderately hot 73.6°F (23.1°C).Heat index
In September, the average heat index is estimated at a blisteringly hot 105.8°F (41°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Heat index specifics point out values are for conditions of shade and a slight breeze. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.
