May weather forecast
Hương Mạc, Vietnam

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

Temperature

The onset of May marks a slight increase in the average high-temperature, moving from 30.8°C (87.4°F) in April to a still tropical 34°C (93.2°F). Nighttime temperatures hover around an average low of 24.8°C (76.6°F) in May.

Heat index

The heat index in May is evaluated at a burning hot 49°C (120.2°F). Stay wary: Heat exhaustion and heat cramps are possible. Heatstroke can ensue from extended effort.
Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.

Humidity

The average relative humidity in May is 74%.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. 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. Experience reduced UV exposure by about half when donning a wide-brim hat.
