May weather forecast
Kim Bảng, Vietnam

As May commences, Kim Bảng experiences its peak temperatures. It is among the hottest months with a recorded 32.9°C (91.2°F) average high temperature, up from 29.8°C (85.6°F) in April. The transition to the hot weather is accompanied by a slight drop in humidity and an increase in the monthly rainfall. Despite the intensifying heat, the amount of sunshine remains significant with daylight reaching its yearly maximum of 13.1 hours. Hence, sunscreen is a must to fend off the robust UV index rating of 7.

Temperature

The onset of May brings a minor temperature shift, with the average high-temperature moving from a moderately hot 29.8°C (85.6°F) in April to a hot 32.9°C (91.2°F). An average low-temperature of 25.7°C (78.3°F) is noted during the nights in May.

Heat index

In May, the average heat index is evaluated at a scorching 44°C (111.2°F). Watchful: Heat cramps and heat exhaustion are predicted. Continued exertion could lead to heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Humidity

In May, the average relative humidity is 73%.

UV index

The months with the highest UV index are April through September, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high threat to health from unprotected exposure to Sun's UV rays for the average person.
Note: A daily high UV index of 7 in May leads to these guidelines:
Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. To cut down UV radiation exposure by about half, sport a wide-brim hat.
