Weather in September
Temperature
The onset of September results in a small decrease in the average high-temperature, moderately receding from a tropical 90.9°F (32.7°C) in August to a moderately hot 84.6°F (29.2°C). September nights cool down to an average low-temperature of 63.5°F (17.5°C).Heat index
The heat index value for September is evaluated at a tropical 93.2°F (34°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are essentially critical for children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
