May weather forecast
Thanh Chương, Vietnam

May, the last month of the spring in Thanh Chương, is a tropical month, with an average temperature varying between 25.7°C (78.3°F) and 32.9°C (91.2°F).

Temperature

With the onset of May, Thanh Chương's average high-temperature experiences a slight rise, moving from April's warm 29.8°C (85.6°F) to a tropical 32.9°C (91.2°F). Thanh Chương in May experiences a low-temperature average of 25.7°C (78.3°F).

Heat index

The average heat index in May is calculated to be a blisteringly hot 44°C (111.2°F). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Note: A maximum high daily UV index of 7 during May translates into the following directions:
Act on precautions and pay attention to sun safety recommendations. Avoidance of sunburn is obligatory. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
