Weather in September
Temperature
With the onset of September, a modest change to a still warm 28.7°C (83.7°F) from August's 28.8°C (83.8°F) is noted in high-temperature. Nighttime temperatures hover around an average low of 23.3°C (73.9°F) in September.Heat index
In September, the heat index is evaluated at a tropical 34°C (93.2°F). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.

A UV Index estimate of 6 to 7 represents a high health risk from unsafe exposure to UV radiation for the average person.Note: The maximum UV index of 6 during September leads to these instructions:
Persist in precautions and follow sun safety policies. Keeping sunburn at bay is imperative. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. To cut down UV radiation exposure by about half, sport a wide-brim hat. Beware! The reflection of water and sand dramatically increases exposure to the UV rays.
