Weather in September
Temperature
As Flora welcomes September, the average high-temperature records at a still tropical 87.4°F (30.8°C), marking an insignificant deviation from the prior month. Flora reports an average low-temperature of 67.3°F (19.6°C) during the nights of September.Heat index
For most parts of September, the heat index is calculated to be a sweltering 100.4°F (38°C). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
