May weather forecast
Phượng Trì, Vietnam

The last month of the spring, May, is another tropical month in Phượng Trì, Vietnam, with an average temperature ranging between max 34°C (93.2°F) and min 24.8°C (76.6°F).

Temperature

May's arrival coincides with a marginal rise in the average high-temperature, moving from April's tropical 30.8°C (87.4°F) to a still hot 34°C (93.2°F). Nightly temperatures drop to an average low of 24.8°C (76.6°F) in May.

Heat index

For most parts of May, the heat index is computed to be a life-threatening hot 49°C (120.2°F). Prudent: Heat cramps and heat exhaustion are likely. Heatstroke becomes imminent with sustained exertion.
One should consider that heat index numbers are for shaded settings and light wind. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Take precautions and adopt sun safety practices. Protection against sunburn is obliged. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
