Weather in September
Temperature
September's onset brings a negligible change in high-temperatures, falling from a hot 94.6°F (34.8°C) in August to a warm 85.8°F (29.9°C). During September, the temperature tends to dip to an average of 66.9°F (19.4°C) at night.Heat index
In September, the average heat index is calculated to be a tropical 93.2°F (34°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Always consider that heat index estimations are for light winds and places in the shade. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
