Weather in September
Temperature
The arrival of September brings an average high-temperature of a still hot 31.4°C (88.5°F), closely following the temperature pattern of August. September nights cool down to an average low-temperature of 24.4°C (75.9°F).Heat index
The heat index in September is calculated to be a fiery hot 39°C (102.2°F). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.Understand that the heat index values take into account shaded locations and mild winds. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. 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 particularly relevant to children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
