April weather forecast
Kỳ Anh, Vietnam

April, like March, in Kỳ Anh, Vietnam, is another warm spring month, with an average temperature ranging between min 22.9°C (73.2°F) and max 29.2°C (84.6°F).

Temperature

The arrival of April witnesses a small shift in the average high-temperature, moving from 25.8°C (78.4°F) in March to a still moderately hot 29.2°C (84.6°F). An average low-temperature of 22.9°C (73.2°F) is observed during April nights.

Heat index

During April, the heat index is estimated at a sweltering 35°C (95°F). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.
In the scope of the heat index, its values resonate with shade and light wind conditions. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

Humidity

The average relative humidity in April is 79%.

Persist in precautions and follow sun safety policies. Keeping sunburn at bay is imperative. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades.
