May weather forecast
Vũ Xá, Vietnam

The last month of the spring, May, is a tropical month in Vũ Xá, Vietnam, with an average temperature varying between 33°C (91.4°F) and 25.3°C (77.5°F).

Temperature

The shift from April to May introduces a subtle increase in the average high-temperature, moving from a moderately hot 29.5°C (85.1°F) to a hot 33°C (91.4°F). Vũ Xá records a mean low-temperature of 25.3°C (77.5°F) in May.

Heat index

The average heat index in May is evaluated at a life-threatening hot 46°C (114.8°F). Vigilance: Heat cramps and heat exhaustion are likely. The likelihood of heatstroke increases with continued activity.
The heat index's values are generally associated with conditions in shade and light breezes. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
