Weather in September
Temperature
The arrival of September brings an average high-temperature of a still tropical 30.6°C (87.1°F), nearly identical to August's 31.5°C (88.7°F). Throughout the month of September, Lương Sơn observes an average nighttime temperature of 22.7°C (72.9°F).Heat index
The heat index in September is evaluated at a scorching 41°C (105.8°F). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.Know that the heat index computations account for shaded terrains and slight winds. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
