Enhancing the warm weather, the humidity takes a slight downturn from April's levels, making daily life bearable in the tropical city.

With this month, Vinh starts witnessing persistent summer winds that provide relief from the soaring temperatures. Rainfall levels see an uptick from April as summer showers become a common sight.

Temperature

May's arrival brings a slight change in high-temperatures, adjusting from a warm 29.8°C (85.6°F) in April to a hot 32.9°C (91.2°F). Throughout May, the average low-temperature in Vinh dips to a moderately hot 25.7°C (78.3°F).

Heat index

Throughout May, the heat index is calculated to be a blisteringly hot 44°C (111.2°F). Watchful: Heat cramps and heat exhaustion are predicted. Continued exertion could lead to heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
