Weather in September
Temperature
September notes an average high-temperature of a still tropical 87.1°F (30.6°C), subtly differing from August's 90.9°F (32.7°C). During September nights, Robinsons witnesses a consistent average temperature of 67.5°F (19.7°C).Heat index
The average heat index in September is appraised at a sweltering 98.6°F (37°C). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.One should consider that heat index numbers are for shaded settings and light wind. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
