April weather forecast
Như Quỳnh, Vietnam

April is a hot spring month in Như Quỳnh, Vietnam, with temperature in the range of an average high of 30.8°C (87.4°F) and an average low of 21.8°C (71.2°F).

Temperature

The start of April brings a subtle rise in the average high-temperature, moving from a moderately hot 26.8°C (80.2°F) in March to a tropical 30.8°C (87.4°F). An average low-temperature of 21.8°C (71.2°F) marks the nights throughout April.

Heat index

The average heat index in April is computed to be a sweltering 39°C (102.2°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Humidity

The average relative humidity in April is 77%.

Rainfall

In April, the rain falls for 14.8 days. Throughout April, 32mm (1.26") of precipitation is accumulated. Throughout the year, in Như Quỳnh, there are 182.1 rainfall days, and 615mm (24.21") of precipitation is accumulated.

Note: The maximum UV index of 6 during April translates into these guidelines:
Deflect overexposure. Sun protection is a necessity. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades.
