May weather forecast
Shenzhen, China

In May, notable weather oscillations continue to take place in Shenzhen. The rainfall tally spikes to an impressive 237mm (9.33"), spanning over fifteen days, marking the descent into the monsoon season. Moreover, progressively rising temperatures pave the way for summer, subjected to concurrent growth in humidity. Succinctly, May represents a stage of increasing weather extremes in Shenzhen.

The shift from April to May in Shenzhen sees a slight increase in the average high-temperature, transitioning from 26.3°C (79.3°F) to a still moderately hot 29.5°C (85.1°F). Shenzhen's average low-temperature is measured at a still moderately hot 23.6°C (74.5°F) during May.

Heat index

The heat index value for May is appraised at a torrid 37°C (98.6°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.
From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
