May weather forecast
Foshan, China

May brings about the transitional phase into the scorching summer months in Foshan. The climate is no longer just warm; the hot days are now making their presence felt, especially during the afternoons. Despite it not being peak summer yet, the sun is still a dominant factor. With a steep increase in rainfall to 284mm (11.18") spread over 18.3 days, it's evident now that the long-drawn rainy season that defines Foshan's summers is upon the city.

Temperature

With the beginning of May, Foshan's average high-temperature sees a minor increase, transitioning from a warm 25.7°C (78.3°F) in April to a still moderately hot 29.3°C (84.7°F). Foshan records an average temperature drop to an agreeable 22.7°C (72.9°F) in May.

Heat index

The heat index in May is evaluated at a fiery hot 37°C (98.6°F). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.
From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.
