May weather forecast
Ban Chiang, Thailand

The last month of the spring, May, is another tropical month in Ban Chiang, Thailand, with an average temperature varying between 27.3°C (81.1°F) and 34.8°C (94.6°F).

Temperature

The start of May sees the average high-temperature at a tropical 34.8°C (94.6°F), showing little difference from April's 36.2°C (97.2°F). Throughout the month of May, the nighttime temperature dips to an average of 27.3°C (81.1°F).

Heat index

May's mean heat index is evaluated at a blazing hot 45°C (113°F). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. 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 remain especially vital for babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

The average daily maximum UV index in May is 7. A UV Index value of 6 to 7 symbolizes a high health hazard from exposure to the Sun's UV radiation for the ordinary person.
Note: The maximum daily UV index, 7 in May, converts into the following recommendations:
Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. 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. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
