Weather in September
Temperature
The ushering in of September brings an average high-temperature of a still moderately hot 29.7°C (85.5°F), closely mirroring the 29.7°C (85.5°F) of August. In the month of September, the average low-temperature usually rests at a pleasant 22.2°C (72°F).Heat index
Throughout September, the heat index is evaluated at a very hot 39°C (102.2°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.Always consider that heat index estimations are for light winds and places in the shade. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. 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 are highly critical to babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
