Weather in April

April ushers in a spell of delightful weather in Hue, characterized by warmer temperatures and a substantial strengthening of sunlight hours.

The beginning of April records an average high-temperature of a hot 30.3°C (86.5°F), almost echoing the conditions of the previous month. Huế's nights in April experience an average temperature drop to a moderately hot 23.3°C (73.9°F).

Heat index

April's mean heat index is calculated to be a very hot 38°C (100.4°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. 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 meaningful for babies and toddlers. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
