Weather in May

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

Temperature

May signals a minor shift in the average high-temperature, moving from April's 30.8°C (87.4°F) to a still hot 34°C (93.2°F). The average temperature drops to a warm 24.8°C (76.6°F) during the night in the month of May.

Heat index

May's mean heat index is appraised at a blazing hot 49°C (120.2°F). Alert: Heat cramps and heat exhaustion are likely to occur. Prolonged exertion can lead to heatstroke.
Consider that heat index readings are for situations in the shade and light wind. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Humidity

The average relative humidity in May is 74%.

Act on precautions and pay attention to sun safety recommendations. Avoidance of sunburn is obligatory. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
