Weather in September
Temperature
The start of September marks an average high-temperature of a still warm 29.7°C (85.5°F), hardly distinguishable from the conditions in August. The average low-temperature, in September, is an agreeable 21.6°C (70.9°F).Heat index
For most parts of September, the heat index is estimated at a very hot 38°C (100.4°F). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.Evaluating the heat index requires understanding its values in the shade and with gentle winds. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'real feel', quantifies the warmth felt when relative humidity is considered. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
