May weather forecast
Mengla, China

May, the last month of the spring in Mengla, is another hot month, with an average temperature ranging between min 18.8°C (65.8°F) and max 30.6°C (87.1°F).

Temperature

Mengla experiences a subtle adjustment in high-temperatures to a still tropical 30.6°C (87.1°F) with the onset of May, maintaining near parity with April's 31.3°C (88.3°F). Mengla's nighttime temperature during May is consistently averaged at a comfortable 18.8°C (65.8°F).

Heat index

The heat index value during May is computed to be a sweltering 37°C (98.6°F). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.
The standards for the heat index are set for locations in shade and under light breezes. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
