May weather forecast
Dongguan, China

May marks the onset of summer in Dongguan, the months of heavier rainfall, and weather conditions typical of Asian tropical climates. Thunderstorms and heavy rains can be anticipated, yet the city remains brightly illuminated under plentiful sunshine hours. The rise in temperature, in association with increased humidity, contributes to the steamy conditions typical of this period. A significant escalation of 113mm (4.45") rainfall can be recorded in May, considerably above April's average.

Temperature

As April transitions into May, a subtle temperature shift is observed, with average highs adjusting from a moderately hot 27.3°C (81.1°F) to a hot 30.5°C (86.9°F). Nighttime temperature dips to a mean of 23.9°C (75°F) during May.

Heat index

In May, the heat index is appraised at a fiery hot 39°C (102.2°F). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.
Consider that heat index readings are for situations in the shade and light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', offers an insight into how hot it feels when we factor in moisture content. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
