Weather in September
Temperature
With the start of September, Upton measures an average high-temperature of a still tropical 87.3°F (30.7°C), not significantly differing from August's 91.4°F (33°C). Upton observes an average low-temperature of 67.3°F (19.6°C) during September.Heat index
September's heat index is computed to be a torrid 100.4°F (38°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. 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 extremely vital to babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
