Guilin Weather in August

Season: Summer 
Overview: 
1. Guilin’s weather in August is pretty hot. Most people cannot even stand to stay outside for over half an hour during midday. 
2. August witnesses considerable rainfall in Guilin, but don’t worry, this won’t significantly affect your outdoor explorations. 
3. August is not suitable for Guilin travel, as it is the peak travel month, and the weather is extremely hot. 
August is in peak summer in Guilin, with daytime highs ranging from 35 to 39°C (95-102°F). The extreme highs can occasionally rise up to 42°C (108°F). During the peak heat hours between 11:00 and 16:00, many visitors find it difficult to stay outdoors for more than half an hour. 

What’s worse, it’s common to experience several consecutive hot days with highs at least exceeding 37°C (99°F). These extended heat waves can make the city feel quite oppressive and sticky, especially when combined with high humidity. 

Although temperatures drop slightly at night, with nighttime lows of 23-27 degrees Celsius (73-81 degrees Fahrenheit), the air often remains muggy. As humidity still lingers after sunset, evening walks are probably not as cool as you imagine, though they are more manageable than midday outings. 

Luckily, mountainous areas enjoy a much cooler climate in August, with an average temperature 3-5°C (5-7°F) lower than urban areas. Another way to escape the summer heat is to visit karst caves, where the average temperature remains about 18-20°C (64-68°F) for the whole year.

August is part of Guilin’s rainy season, with an average precipitation of 173 mm from 15 rainy days. Most rain falls in the form of short showers of relatively low intensity, rarely impacting your outdoor plans. But heavy downpours may happen occasionally. These bursts often last one or two hours and then stop quickly. However, they can temporarily disrupt your plans for river activities. On the one hand, sudden downpours may turn the Li River and Yulong River muddy and yellowish, making the scenery less attractive. On the other hand, rising river levels would possibly cause short suspensions of bamboo rafting and boat cruises. 

It’s necessary to check the weather forecast: in addition to heavy downpours, there is also a risk of typhoons in August. 

Besides, you also need to know that Guilin’s summer weather changes rapidly, and weather forecasts are not always reliable. So, always carry a compact umbrella with you. 
 Guilin in August experiences a pretty humid climate, with an average humidity of 78%. After rainfall, this figure can even rise to 90%. Humidity is actually one of the most challenging aspects of Guilin travel. When the sky is clear, high humidity and strong sunlight can make the perceived temperature much higher than the actual reading. Visitors can easily get heat exhaustion during prolonged outdoor activities. Even when showers temporarily lower the temperature, the increased moisture often makes the air feel somewhat uncomfortable. 
 August’s daylight in Guilin gradually shortens, but is still relatively long, from approximately 13 hours and 15 minutes to 12 hours and 40 minutes per day. However, since the weather of Guilin in August is muggy and uncomfortable, especially during midday hours, you are still advised to include not too many attractions in your daily trip for a better travel experience. 

Sunshine remains strong with the peak UV index reaching 11, and sunlight duration reaches 7 hours per day. River surfaces intensify exposure by reflecting sunlight. For a bamboo rafting event, it’s best to choose a raft with a huge umbrella and apply sunscreen.
