The last month of the spring, May, is another warm month in Nga Yiu Ha, China, with an average temperature ranging between max 28.8°C (83.8°F) and min 24.5°C (76.1°F).

Temperature

Observing a slight rise in May, the average high-temperature shifts from April's warm 25.6°C (78.1°F) to a still moderately hot 28.8°C (83.8°F). In May, Nga Yiu Ha temperatures settle at a low of 24.5°C (76.1°F) during the nights, reflecting a minor change from daytime highs.

Heat index

The heat index value during May is evaluated at a very hot 35°C (95°F). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.
In reference to the heat index, it's for places in shade and with a slight wind. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. 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 are particularly important for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Note: A typical high UV index of 7 in May suggests the following recommendations:
Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
