Weather in September
Temperature
The beginning of September brings a slight decrease in the average high-temperature, transitioning from a tropical 87.6°F (30.9°C) in August to a warm 81.1°F (27.3°C). Throughout September, Sutherland's nights cool down to an average of 63°F (17.2°C).Heat index
The heat index value for September is evaluated at a tropical 86°F (30°C). Uninterrupted activity during exposure could lead to a sense of exhaustion, possibly causing heat cramps.Heat index evaluations are typically in the context of light winds and shaded environments. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
