Weather in September
Temperature
The shift from August to September includes a minor decrease in the average high-temperature, lightly dropping from a very hot 95.7°F (35.4°C) to a tropical 88.7°F (31.5°C). In Trinidad, the average low-temperature during the month of September is a pleasant 68.9°F (20.5°C).Heat index
The heat index for September is calculated to be a sweltering 100.4°F (38°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.When assessing, remember that heat index measurements are for light winds and shaded spots. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Stand by precautions and apply sun safety measures. Evading sunburn is of great importance. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
