May weather forecast
Lashio, Myanmar

May sets the stage for the onset of the monsoon season in Lashio, Myanmar. As the city prepares for significant rainfall, there is a marked shift from the warm and dry climate of the earlier months. Rainfall sees a substantial increase to 78mm (3.07") over more days, signalling the start of the wet period. Nevertheless, the city remains warm with an atmosphere that is rich with the aroma of wet soil and blossoms. While the temperatures continue to be on the higher end, the light breeze provides a reprieve from the heat.

Temperature

As May takes hold, the average high-temperature is a still tropical 31.8°C (89.2°F), nearly mirroring that of the previous month. May nights bring a significant cooling from the heat of the day, with averages of 19.3°C (66.7°F).

Heat index

During May, the heat index is computed to be a very hot 38°C (100.4°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to 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.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Note: The maximum daily UV index of 6 in May converts into the following recommendations:
Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
