Phượng Vũ, Vietnam

May, the last month of the spring in Phượng Vũ, is another tropical month, with an average temperature fluctuating between 24.8°C (76.6°F) and 34°C (93.2°F).

Temperature

As May sets, the average high-temperature shows a slight increase, moving up from a hot 30.8°C (87.4°F) in April to a still tropical 34°C (93.2°F). An average low-temperature of 24.8°C (76.6°F) is expected during May.

Heat index

For most parts of May, the heat index is calculated to be a burning hot 49°C (120.2°F). Prudent: Heat cramps and heat exhaustion are likely. Heatstroke becomes imminent with sustained exertion.
Heat index determinations are made taking into account the shade and light air movements. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Humidity

In May, the average relative humidity is 74%.

UV index

May through September, with an average maximum UV index of 7, are months with the highest UV index. A UV Index of 6 to 7 symbolizes a high health hazard from exposure to the Sun's UV radiation for average individuals.
Note: In May, the maximum UV index of 7 suggests this advice:
Resist extreme sun exposure. Guarding against solar damage is essential. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
