Weather in September
Temperature
September's average high-temperature is a still tropical 31.5°C (88.7°F), maintaining a close comparison with August's 32.6°C (90.7°F). Lai Hạ records an average low-temperature of 23.9°C (75°F) throughout the month of September.Heat index
In September, the heat index is appraised at a scorching 43°C (109.4°F). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially vital to children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Rising body temperatures due to excess heat retention could signify impending heat disorders.
