May weather forecast
Mandalay, Myanmar

In the wake of the intense heat in April, May offers a substantial relief in Mandalay with the onset of the rainy season. Although the temperature range remains high with peaks reaching 36.9°C (98.4°F) and maintaining 27.1°C (80.8°F), it records the highest rainfall in the year reaching 113mm (4.45"). May plays host to a substantial increase in relative humidity, affecting the city's overall climate. Despite long daylight hours, clear visibility may be impeded by heavier cloud presence. Entering into the monsoon season, May exhibits a substantial increase in wind speed, offering a cooling effect against the humid weather.

Temperature

Mandalay experiences an average high-temperature of a still sweltering 36.9°C (98.4°F) in May, subtly different from April's 37.9°C (100.2°F). Mandalay records a mean low-temperature of 27.1°C (80.8°F) in May.

Heat index

Throughout May, the heat index is computed to be a blazing hot 47°C (116.6°F). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.
Observations indicate that the heat index values are for shady locations with light wind. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Humidity

In May, the average relative humidity is 53%.

UV index

The average daily maximum UV index in May is 7. A UV Index value of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV radiation for the ordinary person.
Note: The daily maximum UV index of 7 in May interprets into the following advice:
Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
