A Bit of Hot Weather

Chongqing’s climate in June is characterized by rising temperatures and highly unstable weather conditions. The daytime highs usually range from 26 to 35 degrees Celsius (79-95 degrees Fahrenheit), a bit of a hot level. However, several sunny days feel oppressively hot, with the highest temperature reaching 38°C (100°F), while several rainy days may be noticeably cooler, with temperatures dropping to around 22°C (72°F). Evenings offer a kind of relief. As solar radiation weakens, temperatures drop and river breezes become more active. Nighttime walks along the Yangtze River feel far more comfortable than daytime sightseeing.

In recent years, June in Chongqing tends to be hotter. For example, mid-June 2025 experienced several consecutive days with maximum temperatures exceeding 35°C (95°F), signaling the growing intensity of early-summer heatwaves. Moreover, the humid air enhances the hot feeling, making the perceived temperature even reach around 40°C (104°F) during mid-day hours in the downtown area. If this kind of weather condition occurs during your trip, it’s advisable to drink water frequently, take breaks in shaded spaces, and avoid outdoor exposure for extended hours. 

Regional temperature differences are important to understand when planning your itinerary. Chongqing’s urban core experiences the strongest heat island effect and is thus hotter. In contrast, surrounding districts and mountainous areas such as Wulong, Nanshan, and Jinfo Mountain are typically 2-4°C (4-7°F) cooler, making them ideal for short summer escapes.

The Rainiest Month

 

Lush and Cool Environment

June is one of the wettest months in Chongqing and marks the full arrival of the rainy season. The average precipitation is 211 mm over 7 rainy days. Rainfall is mainly in the form of brief but concentrated downpours in the afternoon or evening. It’s possible to experience heavy thunderstorms, and they can develop rapidly. For example, in June 2025, short-duration downpours could deliver 50-90 mm of rain per hour, triggering secondary hazards such as flash floods and landslides, particularly in mountainous and rural areas. But don’t worry: this is not very common to see. Thus, precipitation won’t cause much disruption to your overall travel experience. However, you are still recommended to pay close attention to the weather alerts just in case. 
 Humidity in June rises sharply, averaging around 80%. When the temperature reaches around 35°C (95°F), it will create a muggy and sticky atmosphere that can make visitors feel very uncomfortable when they stay outside for a long period. 
 June does not offer abundant sunshine, with only 99 sunshine hours monthly. Instead, the sky is often overcast or rainy, with frequent fog in the early morning. Therefore, if you want to watch the city skyline clearly, arrange the activity in the evening. 

Despite limited sunshine hours, it’s not wise to ignore the UV Rays. The average UV index can reach 12, making sun-protective items essential. Even on cloudy days, some ultraviolet rays can penetrate the clouds and harm the skin.
