Weather in September
Temperature
A minor adjustment in Kawelu's average high-temperature is noted with the start of September, touching a still warm 29°C (84.2°F) from August's 28.1°C (82.6°F). Kawelu documents a substantial deviation from daytime highs with a consistent low-temperature of 16.8°C (62.2°F) during September nights.Heat index
September's mean heat index is calculated to be a tropical 31°C (87.8°F). Remaining active during long-lasting exposure could cause fatigue, leading to heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
