April marks a distinct seasonal transition in Ho Chi Minh City. There's a remarkable surge in rainfall to 78mm (3.07") from the previous 17mm (0.67"), signaling the onset of the wet season. Despite this, temperatures remain high, averaging around 35°C (95°F) through the day, and humidity levels start to creep upwards. Nonetheless, the city's vibrant life goes on unabated, with locals and tourists alike adapting to the tropical showers. While it might not be the typical dry season, April in Ho Chi Minh City has its unique appeal with its wet, warm, and humid weather.

Temperature

The arrival of April brings an average high-temperature of a still torrid 35°C (95°F), closely following the temperature pattern of March. Ho Chi Minh City records a steady low-temperature average of 26.3°C (79.3°F) during April.

Heat index

For April, the heat index is estimated at a burning hot 48°C (118.4°F). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.
Always consider that heat index estimations are for light winds and places in the shade. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. 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. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
