Weather in September
Temperature
Transitioning from August to September involves a subtle drop in average high-temperatures, descending from a hot 94.6°F (34.8°C) to a still tropical 87.6°F (30.9°C). In September, the recorded average low-temperature is a refreshing 67.5°F (19.7°C).Heat index
The heat index for September is computed to be a very hot 98.6°F (37°C). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. 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 children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Guard against overexposure. Protection from sun-induced harm is essential. Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
