Sichuan is located in southwestern China and features diverse and complex terrain, encompassing four major landscape units: the Chengdu Plain, the Western Sichuan Plateau, the mountainous areas of southern Sichuan, and the hills of northeastern Sichuan. This diversity creates a climate where weather conditions can vary within a short distance. For travelers, every season offers destinations worth visiting, but the most suitable time is October. In October, Sichuan enjoys its most stable climate, richest landscapes, and most comfortable conditions. This guide details in the best time to visit Sichuan, covering the climate in October, landscapes, travel advantages, helping you formulate a Sichuan travel plan based on the month and weather.
The Overall Climate of Sichuan in October
Comfortable Temperatures
October is a climatic turning point in Sichuan. The hot, humid conditions of summer largely end in late September, while the cold, damp chill of winter has not yet arrived. In October, the Chengdu Plain has average temperatures ranging from 15°C to 22°C. Days are warm and comfortable, with slightly cool mornings and evenings. You avoid the summer heat above 35°C and the cold, damp feeling of winter. The Western Sichuan Plateau has average temperatures of 5°C to 15°C. Days are sunny, and although nights drop to 0°C to 5°C, the plateau’s dry climate makes the perceived temperature higher than the actual reading. Southern Sichuan has average temperatures of 16°C to 25°C, and northeastern Sichuan has 14°C to 23°C, all falling within the most comfortable temperature range for the human body.
Sunny Days
October is one of the least rainy months of the year in Sichuan. The Chengdu Plain receives about 40 mm of average rainfall, only one third of the amount in July and August. The rainy season on the Western Sichuan Plateau ends in late September, and in October the rate of sunny days exceeds 70%, with the highest visibility of the year. Southern and northeastern Sichuan also see significantly less rainfall in October compared to summer. This stable weather means you do not need to carry heavy rain gear, worry about scenic area closures due to heavy rain, or face flight delays, allowing outdoor activities to proceed with almost no weather restrictions.
Ideal Air Quality
The stable airflow and greater number of sunny days in autumn make October the month with the best air quality in Sichuan. The Chengdu Plain typically suffers from heavy smog due to its geography, but in October, frequent cold air movements at moderate intensity help disperse pollutants. The Western Sichuan Plateau has pure air in October, with excellent visibility under blue skies and white clouds. The clear, translucent light in October is suitable for outdoor hiking and breathing fresh air.
Mount Siguniang in October
The Landscapes of Sichuan in October
Mount Siguniang
Mount Siguniang is located in Xiaojin County, Aba Prefecture. Shuangqiao Valley is the most suitable valley to visit in autumn, with colorful forests everywhere, where snowy peaks and vibrant foliage complement each other. Changping Valley requires a hike or horse ride to enter, where the October scenery of colorful forests and snowy mountains is even more pristine. Haizi Valley is famous for its alpine lakes. In October, the lake waters, golden meadows, and reflections of snowy mountains create stunning pictures.
Daocheng Yading
Daocheng Yading is located in Garze Tibetan Autonomous Prefecture. In early October, the meadows at Luorong Pasture turn golden, with Yangmaiyong and Xianuoduoji snow mountains standing magnificently against the blue sky and white clouds. Milk Lake sits at 4,600 meters, its waters milky white. In October, Milk Lake is surrounded by golden meadows and snow mountains, reaching its peak beauty for the year. Five Color Lake sits at 4,700 meters, its waters displaying multiple colors under sunlight. October has a high rate of sunny days, making it the best month to view Five Color Lake.
Jiuzhaigou Valley
The colorful forests of Jiuzhaigou reach their peak from mid October to late October. The leaves of larch, birch, and poplar trees turn golden yellow, orange red, and russet brown, creating a strong contrast with the blue green lake waters. Five Flower Lake shows its richest color layers against the backdrop of the colorful forest, with lakebed sediments and algae displaying shades of blue, green, yellow, and purple. Long Lake is the highest and largest lake in Jiuzhaigou. In October, Long Lake is surrounded by golden and red colorful forests, with mirror like reflections. Mirror Lake offers its clearest reflections on windless mornings, with reflections of both the colorful forest and snowy mountains appearing simultaneously on the water surface.
Huanglong
Huanglong is about 100 kilometers from Jiuzhaigou and is usually visited together with it. The travertine pools of Huanglong still have abundant water in October, displaying blue green colors. Five Color Pond is the core landscape of Huanglong, with hundreds of travertine pools of varying sizes stacked in layers. In October, the water colors are at their most vibrant. The surrounding larch and fir trees turn golden yellow in October, creating a strong contrast with the blue green pool waters. The waters of Zhengyan Pond vary richly in color, from light blue to deep green, and are most brilliant under October sunlight.
Downtown Chengdu
The weather at the Chengdu Research Base of Giant Panda Breeding is suitable in October, with pandas spending more time outdoors than in summer, increasing your chances of seeing active pandas. Kuanzhai Alley and Jinli see many visitors in October, but the cool climate makes it pleasant to sit in outdoor courtyards enjoying Sichuan cuisine and gaiwan tea. Heming Teahouse in People’s Park remains a popular spot for locals to relax and drink tea in October, with ginkgo trees beginning to turn yellow in late October. The Chengdu Museum and Jinsha Site Museum see fewer visitors in autumn, making them suitable for a half day of detailed exploration.
Leshan Giant Buddha
The Leshan Giant Buddha is located in Leshan City and is the largest cliff side stone carved Buddha in China. October temperatures are suitable, without the summer heat above 35°C or the cold river wind of winter. Visitors can choose to hike up for a view of the Buddha’s head or take a boat on the river to see the full body. In October, the water levels at the confluence of the Min River, Qingyi River, and Dadu River are stable, making boat tours safer and more comfortable.
Mount Emei
Mount Emei is one of the four sacred Buddhist mountains in China. October temperatures on Mount Emei are suitable, around 18°C to 22°C at the base and 5°C to 10°C at the summit. Climbing to the Golden Summit avoids the intense heat of summer and the snow blocked paths of winter. The Golden Summit’s Samantabhadra statue and sea of clouds appear more frequently in October, with visibility significantly better than in summer. Temples such as Baoguo Temple, Fuhu Temple, and Qingyin Pavilion appear more rustic and ancient against the backdrop of autumn colors.
The Advantages of Sichuan in October
Temperature Advantage
In July, August, and September, temperatures on the Chengdu Plain and in southern Sichuan often reach above 35°C. Visitors to the Leshan Giant Buddha scenic area suffer through the stuffy heat and intense sunlight by the river, while hiking Mount Emei requires significantly more physical exertion than in October. Additionally, Daocheng Yading experiences frequent afternoon rainfall in July and August, with the three sacred mountains fully visible less than 30% of the time. In contrast, traveling to Sichuan in October means you do not need to worry about these issues at all. During this season, temperatures on the Chengdu Plain drop to around 25°C, the rainy season ends on the Western Sichuan Plateau, and sunny days are common.
High Altitude Adaptation Advantage
The climate on the Western Sichuan Plateau in October is most friendly for first time visitors to high altitude areas. Compared to winter, daytime temperatures in October are higher, and perceived temperatures are much higher than winter even at elevations above 4,000 meters, so your body does not have to cope with severe cold while adapting to altitude hypoxia. Compared to summer, humidity in October is lower, and common altitude sickness symptoms like chest tightness and difficulty breathing are less severe in dry conditions. Although the temperature difference between day and night on the Western Sichuan Plateau is large, layering your clothing allows you to wear a light jacket during daytime hikes and add a down jacket at night.
Smooth Travel Advantage
In October, all scenic areas and roads in Sichuan are in optimal condition for travel. The long hiking route at Daocheng Yading is open, allowing visitors to hike from Luorong Pasture to Milk Lake and Five Color Lake, an experience impossible in winter. Balang Pass at Mount Siguniang is free of snow concerns, so self driving visitors can go directly from Chengdu via Wolong to Rilong Town without detours. All boardwalks and viewing platforms at Jiuzhaigou are open. High altitude passes like Zheduo Mountain and Jianziwan Mountain are free from snow blockages, and the Western Sichuan small loop and Daocheng Yading route are completely clear. No scenic areas close or reduce their opening scope due to weather or road conditions in October.
Crowd and Price Advantage
October includes the National Day holiday, and the first seven days are indeed the peak for crowds and prices. However, between October 10 and 25, crowds quickly return to normal levels. Waiting times at Jiuzhaigou drop from 2 to 3 hours during National Day to 20 to 30 minutes. The long hiking route at Daocheng Yading no longer requires queuing at narrow sections. Kuanzhai Alley and Jinli in downtown Chengdu return to normal density. Hotel prices in popular accommodation areas like the entrance to Jiuzhaigou and Yading Village drop by 30% to 50% compared to National Day. This period completely overlaps with the peak of the colorful forests.

Tips for Sichuan Travel in October
Booking
October is the peak travel season of the year in Sichuan, and tickets for popular scenic areas like Jiuzhaigou, Daocheng Yading, and Mount Siguniang are in high demand. Regular tickets for Jiuzhaigou must be booked 14 days in advance through the official WeChat public account. With daily visitor limits, tickets for mid October usually sell out within one hour of release. Daocheng Yading tickets open for booking 7 days in advance. It is recommended that you complete your ticket booking as soon as your itinerary is confirmed, and not wait until after arriving in Sichuan.
Accommodation
In October, accommodation prices around the Western Sichuan Plateau and Jiuzhaigou are 50% to 100% higher than usual. It is recommended that you book hotels one month in advance and choose options with free cancellation to accommodate itinerary changes. If you are on a budget, you can choose to stay in small towns 30 to 50 kilometers from the scenic areas, where prices are usually lower. Chengdu and Leshan have more accommodation options, with prices notably affected by National Day.
Altitude Sickness
Most destinations on the Western Sichuan Plateau have elevations exceeding 3,000 meters, and some hiking routes at Daocheng Yading exceed 4,500 meters. It is recommended that you avoid strenuous exercise, alcohol, and hot showers within 24 hours of arriving at high altitude areas. You may take Rhodiola rosea a week in advance (results may vary), and carry portable oxygen canisters and common medications. If you experience severe headache, vomiting, or difficulty breathing, descend to a lower altitude immediately and seek medical attention. October is the season with the largest temperature differences between morning and evening on the Western Sichuan Plateau, and catching a cold can worsen altitude sickness symptoms.
