Weather in September
Temperature
The onset of September brings with it an average high-temperature of a still warm 28.5°C (83.3°F), showing a negligible variation from the month before. Throughout the month of September, Kokamau observes an average nighttime temperature of 23.4°C (74.1°F).Heat index
September's heat index is computed to be a tropical 34°C (93.2°F). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.Records show heat index calculations are tailored for shaded regions and mild winds. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
