Weather in September
Temperature
September implies a soft temperature shift, with average high-temperatures reducing from August's tropical 87.1°F (30.6°C) to a moderately hot 81.3°F (27.4°C). Throughout the month of September, the nighttime temperature dips to an average of 60.1°F (15.6°C).Heat index
The heat index in September is estimated at a hot 86°F (30°C). With ongoing exposure and activity, one might experience weariness, and heat cramps could ensue.When assessing, remember that heat index measurements are for light winds and shaded spots. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. 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. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
