September weather forecast
Quảng Kim, Vietnam

The first month of the autumn, September, is still a tropical month in Quảng Kim, Vietnam, with an average temperature ranging between max 30°C (86°F) and min 18.7°C (65.7°F).

Temperature

Quảng Kim's weather in September indicates an average high-temperature of a still hot 30°C (86°F), nearly consistent with the 31°C (87.8°F) of August. Throughout the month of September, the average temperature dips to a refreshing 18.7°C (65.7°F) at night.

Heat index

In September, the average heat index is estimated at a very hot 37°C (98.6°F). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Humidity

In Quảng Kim, the average relative humidity in September is 77%.

Rainfall

In September, the rain falls for 20.4 days. Throughout September, 69mm (2.72") of precipitation is accumulated. Throughout the year, there are 188.3 rainfall days, and 770mm (30.31") of precipitation is accumulated.

Sunshine

The average sunshine in September is 10.2h.

UV index

The months with the highest UV index are March through September, with an average maximum UV index of 6. A UV Index reading of 6 to 7 represents a high health hazard from unsafe exposure to UV radiation for the ordinary person.
Note: A maximum high UV index of 6 in September translates into the following recommendations:
Fend off overexposure. Sun protection is vital. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
