Weather in September
Temperature
Ninh Phụng, Vietnam, experiences a transition to a moderately hot 29.6°C (85.3°F) in average high-temperatures with the arrival of September, not greatly differing from August's 30.7°C (87.3°F). The average low-temperature, in September, is a still warm 24.2°C (75.6°F).Heat index
In September, the heat index is evaluated at a sweltering 36°C (96.8°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', takes into account both air temperature and humidity to illustrate what people actually feel. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
