Weather in September
Temperature
The start of September marks an average high-temperature of a still moderately hot 27.2°C (81°F), hardly distinguishable from the conditions in August. Throughout September, the average low-temperature dips to a refreshing 16.1°C (61°F).Heat index
September's heat index is evaluated at a hot 30°C (86°F). Remaining active during long-lasting exposure could cause fatigue, leading to heat cramps.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
