September weather forecast
Trà Lâm, Vietnam

September, the first month of the autumn in Trà Lâm, is still a tropical month, with temperature in the range of an average low of 24.2°C (75.6°F) and an average high of 31.7°C (89.1°F).

Temperature

The advent of September brings an average high-temperature of a still hot 31.7°C (89.1°F), almost identical to the preceding month. Trà Lâm experiences a mean low-temperature of 24.2°C (75.6°F) during September.

Heat index

Throughout September, the heat index is computed to be a blisteringly hot 43°C (109.4°F). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.
Data suggests that the heat index is set for environments in shade and with a light wind. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Humidity

August and September, with an average relative humidity of 80%, are the most humid months.

UV index

May through September, with an average maximum UV index of 7, are months with the highest UV index. A UV Index value of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV radiation for the average person.
Note: The maximum UV index of 7 during September leads to these instructions:
Inhibit overexposure. Warding off sun damage is of utmost importance. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
