Weather in September
Temperature
With average high temperatures of 27.3°C (81.1°F) and lows of 26.1°C (79°F), September is the coldest month.Heat index
During September, the heat index is appraised at a tropical 30°C (86°F). Prolonged exposure and physical activity might induce exhaustion, potentially causing heat cramps.One should consider that heat index numbers are for shaded settings and light wind. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
