April weather forecast
Tây Hồ, Vietnam

April in Tây Hồ, Vietnam, is a tropical spring month, with an average temperature fluctuating between 21.8°C (71.2°F) and 30.8°C (87.4°F).

Temperature

The shift into April is accompanied by a modest temperature increase, with the average high-temperature edging up from a moderately hot 26.8°C (80.2°F) in March to a tropical 30.8°C (87.4°F). Throughout April, Tây Hồ records an average temperature of 21.8°C (71.2°F) at night.

Heat index

The heat index in April is calculated to be a torrid 39°C (102.2°F). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
