Weather in September
Temperature
The arrival of September brings an average high-temperature of a still tropical 88.5°F (31.4°C), subtly diverging from August's 91.9°F (33.3°C). The nighttime temperature dips to an agreeable 69.1°F (20.6°C) on average during September.Heat index
In September, the average heat index is evaluated at a blistering 105.8°F (41°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are largely significant for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
