Temperature

May introduces a minor temperature shift, with average high-temperatures adjusting from April's moderately hot 27.3°C (81.1°F) to a tropical 31°C (87.8°F). An average low-temperature of 25.3°C (77.5°F) is observed during May nights.

Heat index

The average heat index in May is calculated to be an extremely hot 41°C (105.8°F). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.
Heat index determinations are made taking into account the shade and light air movements. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'real feel' or 'feels like', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Humidity

In May, the average relative humidity is 80%.

Rainfall

In Mễ Xá, during May, the rain falls for 20.4 days and regularly aggregates up to 103mm (4.06") of precipitation. In Mễ Xá, during the entire year, the rain falls for 205.9 days and collects up to 966mm (38.03") of precipitation.

UV index

The months with the highest UV index 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 average individuals.
Note: A daily high UV index of 7 in May leads to these guidelines:
Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
