Weather in September

September's heat index is estimated at a tropical 86°F (30°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.Know that the heat index computations account for shaded terrains and slight winds. 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 achieved by amalgamating air temperature with the relative humidity readings. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. 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 hold particular importance for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
