December weather forecast
Vinh Long, Vietnam

Finally, December ushers in a significant change in Vinh Long, wrapping up the year by offering a respite from the preceding months of rainfall. This marked decrease in rainfall, averaging at 15mm (0.59"), points towards the drier months to come. A steady decline in average cloud cover brings longer hours of sunlight impacting positively on day temperatures. With the shift into January, weather patterns suggest a full circle return to similar climatic characteristics that were observed at the beginning of the year. Despite the drop in rain, the wind speed fluctuates around 10km/h (6.2mph), creating a coolness in the atmosphere that is comfortable and welcoming.

Temperature

December, recording an average high temperature of 30.8°C (87.4°F) and a low temperature of 22.8°C (73°F), is Vinh Long's coldest month.

Heat index

December's heat index is computed to be a sweltering 39°C (102.2°F). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.
Note that heat index values are valued for light wind and location in the shade. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Humidity

In December, the average relative humidity is 76%.

Keep in mind that shade structures may not provide complete protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
