Overview: 
1. Chengdu’s weather in June features hot mid-day hours and cooler nights.
2. June marks the rainy season in Chengdu, bringing frequent showers and occasional thunderstorms. But they won’t impact your trips significantly. 
3. June is not a bad month for the Chengdu tour: the weather is okay, the tourist number hasn’t reached its peak, and the travel cost is manageable. 
 In June, Chengdu’s climate is a little hot, with daily highs ranging from 28°C to 33°C (82-91°F). But don’t worry, this month, the number of days with temperatures exceeding 35 degrees Celsius (95 degrees Fahrenheit) typically does not exceed one per year. However, in exceptional years, such as 2025, the number of such hot days reached 7 in June, with daily highs soaring to 41°C (106°F) occasionally, when it's best to avoid staying outside for too long during midday. Rainy weather may cool down the temperature a little. 

There is a considerable temperature difference between day and night. After sunset, temperatures drop significantly to a comfortable 17-22°C (63-72°F). Therefore, make sure to check the weather forecast in advance and adjust your clothing accordingly if you plan to go out in the early morning or at night. 

Destinations near Chengdu, like Mount Qingcheng, offer temperatures lower than those in the city center. Its lush vegetation and waterfalls make it an ideal summer retreat. 
 June marks the beginning of the rainy season in Chongqing. The precipitation remains at a moderate level, which is 107 mm over 15 rainy days on average. You might experience light rain, moderate rain, heavy downpours and thunderstorms. 

Light showers and moderate rain usually have a limited impact on your outdoor activities, as long as you carry umbrellas. However, intense rainfall events are frequent, in the form of brief but strong downpours, thunder, and winds. They often trigger urban flooding and geological hazards like mudslides, making outdoor recreation inadvisable. Historical data shows June recorded a maximum hourly rainfall of 60 mm. Therefore, it’s always a good idea to check the forecast regularly and adjust your travel plans accordingly. 
 Due to the increasing precipitation in June, Chengdu experiences a quite humid climate, with an average humidity level of 76%. Fortunately, the air doesn’t feel unbearable most of the time. Just try to avoid going out at midday. 
 June boasts the longest daylight hours of the year, averaging 14 hours daily. This allows visitors to have a relaxing trip without rushing through tightly packed travel plans. But remember to check the opening hours of each attraction ahead of time when planning your trip.

Although sunshine hours are short, lasting only about 4 hours, don't overlook the fact that the UV index peaks at 11. Sun protection is essential.
