Weather in
Tianjin in
August is a near replica of
July, maintaining the summery zeal although with slightly less rainfall. The amount of daylight hours diminishes, but the UV index is still at a peak. Temperatures remain almost identically high as they oscillate between 21.9°C (71.4°F) and 30.2°C (86.4°F).
Temperature
As Tianjin transitions from July to August, the average high-temperatures adjust to a still hot 30.2°C (86.4°F), nearly the same as the previous 31°C (87.8°F). During August, the temperature is averaged to a low of 21.9°C (71.4°F) at night.
Heat index
The average heat index in August is estimated at a sweltering 37°C (98.6°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
Humidity
With an average relative humidity of 77%, August is the most humid month.
Rainfall
In Tianjin, in August, during 10.2 rainfall days, 146mm (5.75") of precipitation is typically accumulated. In Tianjin, during the entire year, the rain falls for 63.8 days and collects up to 544mm (21.42") of precipitation.
Daylight
In Tianjin, the average length of the day in August is 13h and 40min.

Sunshine
The average sunshine in August is 7.2h.
UV index
June through August, with an average maximum UV index of 9, are months with the highest UV index. A UV Index of 8 to 10 symbolizes a very high health vulnerability from unsafe exposure to UV radiation for the ordinary person.
Note: In August, the maximum UV index of 9 suggests this advice:
Taking safety measures is non-negotiable; skin and eyes can be swiftly affected if neglected. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration. A broad-spectrum sunscreen of SPF 30+ should be used liberally and reapplied every two hours or post an outdoor workout or swim.
