Month-by-month weather, crowd levels, and the best (and worst) windows for Guilin, Yangshuo, and Longji.
Bottom line: April-May and September-October are best: mild weather, full rivers, and green karst. July-August is hot but lush; December-February is cold, sometimes grey, and quiet with few tourists. Avoid National Day (early October) and the Spring Festival.
Guilin's scenery is good all year, but comfort and crowds vary a lot. The guide below helps you pick a window and pack right.
| Month | Temp | Rain | Crowds | Recommendation |
|---|---|---|---|---|
| Jan | 5-12C | Low | Low | Quiet, cold, cheap |
| Feb | 7-14C | Low | Low-Med | Pre-Spring Festival calm |
| Mar | 11-18C | Med | Med | Greening, pleasant |
| Apr | 16-23C | Med-High | Med-High | Great weather |
| May | 20-27C | High | Med | Lush, fewer crowds than Oct |
| Jun | 23-30C | High | Med | Wet but green |
| Jul | 25-33C | High | High | Hot, domestic peak |
| Aug | 25-33C | High | High | Hot, afternoon storms |
| Sep | 22-30C | Med | Med-High | Excellent, golden start |
| Oct | 18-26C | Low-Med | High | Best weather, busiest |
| Nov | 13-21C | Low | Low-Med | Cool, quiet, good |
| Dec | 7-15C | Low | Low | Cold, few tourists |
Bottom line: September is one of the two best months of the year. Summer's heat and rain ease off, the karst light turns clear and golden, Longji's rice ripens toward its late-September harvest, and the October peak-season crowds and prices have not arrived yet. Aim for mid-to-late September for the best combination of weather, colour, and space.
Early September still carries a touch of summer — daytime highs around 30°C and occasional afternoon showers — but by mid-month the humidity drops and the days settle into a comfortable 22-30°C. Mornings and evenings turn pleasantly cool, especially on the water and at Longji's higher elevation. Rainfall is well below the June-August peak, though a late-season storm or typhoon remnant can still pass through, so keep one flexible half-day in the plan. Pack light, breathable layers, a packable rain shell, comfortable walking shoes, and sunscreen; a thin fleece earns its place for sunrise starts at the terraces or an early Li River cruise.
September is the smart alternative to October. You get essentially the same clear, golden light while hotels and the Li River cruise stay at normal-season rates, and the viewpoints are busy but not packed. The two caveats: the first cool weekend can bring a short domestic wave, and if the Mid-Autumn Festival holiday falls in late September (the lunar date shifts each year), expect a brief bump in travellers and book your rooms a little earlier. Compared with the first week of October, when prices can roughly double, mid-September is one of the best value windows of the year. Treat pricing as indicative and confirm current rates when booking.
Do not plan around the very start of the month if you dislike heat — the first week can still feel like August. Watch the forecast for late typhoon remnants, which mostly mean a day of heavy rain rather than a washed-out trip. And if your dates are flexible, avoid running straight into the National Day holiday on October 1: the last couple of days of September can see the first wave of domestic travellers positioning for Golden Week, so schedule Longji or the Li River cruise earlier in your trip rather than at its tail.
Start early to use the cool light: a morning bamboo raft or e-bike loop on the Yulong River, a late-morning climb such as Moon Hill while the air is still mild, a long lunch, and a sunset viewpoint such as Xianggong Hill or the Xingping 20-yuan bend. Slot Longji as a full day — roughly 2.5 hours each way — and keep the harvest as its centrepiece. Ready-made structures are in the 3-day, 5-day, and 7-day itineraries, and the weather by month page has the detailed temperature and rainfall tables.
Source & verification: September conditions are typical climate patterns for the Guilin region, not guarantees. Temperatures, rain, and festival dates vary year to year; check the short-range forecast before outdoor bookings.
Spring (Mar-May): the karst turns green, rivers fill, and misty mornings make the best photos. April-May are the most comfortable months; pack a light rain layer. Late February to mid-March also brings the Yangshuo rapeseed flower season along the Yulong River.
Summer (Jun-Aug): hot and humid with afternoon thunderstorms. The landscape is at its most lush and the rivers fullest, but domestic tourists peak in July-August. Start early, rest at midday, and hydrate.
Autumn (Sep-Oct): widely considered the best time - cool, clear, and golden. October is the most popular and can be crowded; September is the smarter pick.
Winter (Nov-Feb): cold, sometimes near freezing, with grey low-cloud days. You get empty sights and low prices, but the Li River can look muted and Longji's fields are drained and brown.
Not every month suits every kind of trip. Match your travel style to the season.
Yangshuo sits about 65 km south of Guilin and shares the same broad climate, but the experience on the ground is not identical. The town is wrapped in karst peaks and sits lower and more open than the city, which changes how the weather feels even when the forecast looks the same.
| Period | What Yangshuo is like | Verdict |
|---|---|---|
| April – May | Warm, green, comfortable riding weather; occasional showers | Best for cycling and first visits |
| June – July | Hot, humid and the wettest window; river levels can rise fast | Expect rain; rafting may pause |
| August | Still hot, fewer downpours than July, busier with domestic travel | Workable, start early |
| September – October | Clearest skies, comfortable temperatures, golden fields | Best overall |
| November – March | Cool and quiet, flat light, cold mornings on the water | Cheapest, least colourful |
The rain caveat. June and July bring the heaviest rainfall, and this is when the Li River and Yulong River can rise quickly. Bamboo rafting is sometimes suspended after heavy rain, and the riverside paths turn slippery. If you are travelling in this window, build in a flexible day and check conditions locally before booking rafting or a climbing session.
Best months for Yangshuo specifically: late April to May and September to October. You get comfortable temperatures for cycling, the clearest light on the karst, and the terraces either flooded or golden depending on which end you pick. For month-by-month temperatures and rainfall figures, see our Yangshuo and Guilin weather by month.
Yangshuo in detail. Yangshuo sits lower and more open than Guilin, holds more humidity, and is far more exposed to rain because almost everything you do there is outdoors. We cover all of that month by month — including what the wet season does to rafting and cycling — in the dedicated best time to visit Yangshuo guide.
The terraces change completely through the year. May-June is the mirror-flooded planting season - the tiered fields fill with water and reflect the sky. Late September to early October is the golden harvest, when the rice ripens to amber. Both windows are spectacular and draw photographers. Avoid late winter, when the fields are drained and brown. Our Longji guide has village-by-village detail.
| Period | What the terraces look like | Verdict |
|---|---|---|
| April – early June | Flooded mirror fields before planting; dramatic sunrise reflections | Best for classic photos |
| July – August | Solid lush green as the rice fills in | Good, hazier light |
| Late Sept – mid Oct | Golden rice before the cut; clearest air | Best weather, busiest |
| November – March | Bare or lightly flooded terraces, mist, occasional snow up top | Cheapest, least colourful |
Longji sits about 95 km north of Guilin and roughly 2.5 hours away, so it deserves its own planning rather than being squeezed into a Yangshuo day. Full village, ticket and access detail is in our Longji Rice Terraces guide, and the transport options are covered in how to get to Longji.
Want to do more than look? During the golden harvest (roughly late September to mid-October) you can join villagers to actually cut the rice — a short, family-run experience unique to this window. Our Longji rice harvest experience guide covers when it runs, how to book, what it costs, and what to wear.
The Li River is fullest after spring and summer rain, which makes the peaks greener and the cruise more dramatic. In late autumn and winter the river is lower and calmer - still beautiful, just less voluminous. Cruises run year-round, but the famous "sea of peaks in mist" shots are most likely in spring and early summer.
If photos are the point, time your visit: May-June for flooded terraces and lush green peaks after rain; September-October for golden rice and clear autumn light; winter for moody mist but bare terraces. The Li River "sea of peaks in cloud" shot is most likely on a spring or early-summer morning after rain. Sunrise at Longji and the 20-yuan viewpoint near Xingping are the iconic frames worth building a day around.
Guilin follows the standard Chinese holiday calendar. Around Longji, the Yao and Zhuang communities mark the rice cycle with harvest celebrations and traditional clothing festivals, often in autumn - colorful but busier. There is no fixed-date international event that drives travel here, so your timing is mostly about weather and holidays rather than a festival calendar.
March-April and late September-November are the sweet spots: good weather with fewer tourists than October. If you can travel mid-week and skip the National Day week, you get lower hotel rates and emptier viewpoints. This is also the easiest time to book a specific riverside resort without a long lead time, and trails and rafts feel relaxed rather than crowded.
Two local events shape the calendar. The Longji Red Rice Festival (usually late September) and the spring ploughing rituals (April) draw domestic photographers to the terraces, but they are small and rural — they add atmosphere more than crowding. The bigger force is the national holiday schedule: National Day (Oct 1–7) and Chinese New Year (late Jan/Feb) send hundreds of millions of domestic travelers across the country, and Guilin–Yangshuo is a top destination. Avoid those two weeks if you can; prices can double and major sites get jammed. The weekly rhythm also matters: Friday–Sunday is noticeably busier than Monday–Thursday, so if your dates are flexible, arrive midweek for shorter lines at the Li River cruise and Yulong River rafts.
Karst landscapes photograph best in soft, low light. Aim for 7:00–9:00 am for mist on the river and warm side-light on the peaks, and 5:00–6:30 pm for golden-hour glow on the limestone. After rain, the hills turn a deeper green and low cloud wraps the tops — the most dramatic shots often come the morning after a downpour. Avoid harsh midday sun, which flattens the relief. For the terraces, the reflecting-water period (early May) and the golden harvest (late September) are the two can't-miss windows.

April, May, September, and October are best - mild temperatures, green karst, and full rivers. October is the most popular and can be busy; May offers lush scenery with fewer crowds.
Avoid the first week of October (National Day) and the Spring Festival period - prices double and crowds peak. July-August is hot and humid but fine if you tolerate heat and afternoon storms.
December to February is cold (sometimes near freezing), grey at times, and quiet. You get low prices and empty sights, but the Li River can look muted and some rural spots feel bare.
May-June for the mirror-flooded planting season, and late September to early October for the golden harvest. Avoid late winter when fields are brown and drained.
Yes. Spring and summer (after rain) bring fuller, greener rivers and dramatic peaks; late autumn and winter are lower and calmer. Cruises run year-round regardless.
Spring/autumn: light layers and a rain jacket. Summer: breathable clothes, sunscreen, and an umbrella. Winter: a warm coat, especially for early-morning cruises and Longji.
Yes — it is one of the two best months. Summer's heat and rain ease, the karst light turns clear and golden, and Longji's rice ripens toward the late-September harvest, all before the October peak-season crowds and prices. Early September can still feel summery, so aim for mid-to-late in the month, keep one flexible half-day for a passing storm, and avoid running straight into the National Day holiday at the very end.
Late September, if you can manage it. It combines the best of the two classic windows: the clear, golden autumn light that October is famous for, and the tail of the lush green season, without October's peak prices and National Day crowds. Longji's terraces turn gold from late September and the harvest atmosphere adds something no other month offers. If late September is impossible, take May: the hills are at their greenest, the rice paddies are flooded into mirrors, and crowds are moderate — the trade-off is a higher chance of rain, so build in one flexible day. October itself is beautiful but book everything well ahead and skip the 1-7 holiday week entirely. April is the quieter third choice, with mild weather and fresh growth, though the light is flatter for photography.
September-October for golden rice terraces and mild weather. April-May for blooming flowers.
Hot and rainy, but also peak season. Book everything in advance.
Once you choose a month, match it to a 3, 5, or 7-day itinerary.
