Weather in May

May, the last month of the autumn in Boyolali, is another tropical month, with temperature in the range of an average low of 24.5°C (76.1°F) and an average high of 31.3°C (88.3°F).

Temperature

The beginning of May reveals an average high-temperature of a still tropical 31.3°C (88.3°F), showing minimal deviation from the previous month. The month of May records an average low-temperature of 24.5°C (76.1°F).

Heat index

Throughout May, the heat index is evaluated at an extremely hot 42°C (107.6°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.
In terms of the heat index, values are set with light wind and shade conditions in mind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

The average relative humidity in May is 79%.

January through December, with an average maximum UV index of 7, are months with the lowest UV index. A UV Index value of 6 to 7 symbolizes a high health risk from exposure to the Sun's UV radiation for ordinary individuals.
Note: A daily high UV index of 7 in May leads to these guidelines:
Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Enhance your sun protection with tightly woven, yet airy clothing.
