May weather forecast
Nguyên Khê, Vietnam

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

Temperature

The start of May brings a subtle rise in the average high-temperature, moving from a tropical 30.8°C (87.4°F) in April to a still hot 34°C (93.2°F). Nighttime temperature experiences an average drop to a moderately hot 24.8°C (76.6°F) in May.

Heat index

The heat index value for May is evaluated at a blazing hot 49°C (120.2°F). Keep alert: Heat cramps and heat exhaustion are probable. Heatstroke is a potential danger with continued physical activity.
Know that the heat index computations account for shaded terrains and slight winds. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', ties air temperature with relative humidity to produce the perceived temperature sensation. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

UV index

The months with the highest UV index in Nguyên Khê are May through September, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high threat to health from exposure to the Sun's UV rays for the ordinary person.
Note: The daily high UV index of 7 during May translates into the following recommendations:
Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days.
