Twelve months of temperatures, rainfall, and humidity - and what each month means for your trip.
Bottom line: Guilin has a humid subtropical climate: hot wet summers, mild dry autumns, and damp chilly winters. The most comfortable months are October and November (18-26 C, low rain); the wettest are May and June, when rainfall can exceed 300 mm a month.
Understanding the rainfall pattern matters more than the temperatures here. Guilin sits in the monsoon belt, so the year divides into a wet first half and a drier second half. That single fact explains most of the difference between a trip of blue skies and one of mist, cancellations, and muddy terrace paths.
| Month | Avg high / low | Rainfall | What to expect |
|---|---|---|---|
| January | 12 / 5 C | about 60 mm | Coldest month, damp and grey, fewest crowds |
| February | 14 / 7 C | about 80 mm | Warming slowly, misty, Spring Festival crowds possible |
| March | 18 / 11 C | about 130 mm | Spring begins, showers return, greenery comes back |
| April | 23 / 16 C | about 200 mm | Warm and wet, mist over the river, good for photos |
| May | 27 / 21 C | about 300 mm | Heavy rain begins, terraces flood, humid |
| June | 30 / 24 C | about 320 mm | Wettest month, frequent downpours, flooding risk |
| July | 33 / 26 C | about 200 mm | Hot and humid, afternoon storms, school holidays |
| August | 33 / 26 C | about 170 mm | Still hot, typhoon influence, fewer rainy days |
| September | 30 / 23 C | about 80 mm | Rain drops sharply, one of the best months |
| October | 26 / 18 C | about 70 mm | Clear skies, comfortable, peak season |
| November | 21 / 13 C | about 60 mm | Dry and pleasant, cool evenings, golden terraces |
| December | 15 / 8 C | about 40 mm | Driest month, chilly mornings, quiet |
Spring is green, warm, and increasingly wet. March is pleasant with light showers; by May the region is in full monsoon mode. The upside is atmosphere - mist on the Li River and water-filled rice terraces are the images people travel here for, and both are spring phenomena. The downside is cancelled outdoor plans and slippery paths, so build indoor alternatives like caves or the city into your itinerary.
Summer is hot, humid, and the wettest part of the year overall, though it comes as heavy bursts rather than constant grey. June is the single wettest month. July and August bring temperatures in the low thirties with uncomfortable humidity, and typhoons in the wider region can disrupt transport. It is also peak domestic holiday season, so popular sites are crowded. The compensation is lush scenery and the lowest accommodation pressure outside public holidays.
This is the sweet spot. Rainfall collapses from September, humidity drops, and temperatures settle into a comfortable range. October and November offer the clearest skies of the year, which matters for both photography and simply enjoying being outdoors. The trade-off is that this is peak season for domestic tourism, particularly the first week of October, when prices and crowds spike for the National Day holiday.
Winter is mild by northern standards but feels colder than the thermometer suggests, because the humidity is high and most buildings lack heating. Snow is rare in the city. The advantages are real, though: this is the driest stretch of the year, the crowds are gone, and hotel rates are at their lowest. It is a reasonable time to come if you layer properly and accept greyer light.
Humidity sits around 70-80 percent for much of the year, which amplifies both summer heat and winter chill. Rain usually arrives in intense episodes rather than all-day drizzle, so a wet month still contains plenty of usable days - the practical advice is to plan outdoor activities in the morning, when showers are less likely, and keep flexible indoor options for the afternoon.
| If you want | Best months | Why |
|---|---|---|
| The most reliable weather | Oct-Nov | Lowest rainfall, clear skies, comfortable temperatures |
| Mist and atmospheric photos | Apr-May | Morning mist over the river, soft light |
| Flooded mirror terraces | May-early Jun | Water-filled fields reflect the sky |
| Golden harvest terraces | late Sep-mid Oct | Rice turns gold before harvest |
| Fewest crowds and lowest prices | Dec-Feb | Driest months, but cool and grey |
| Warm water activities | Jul-Aug | Hot, with rafting at its most appealing |
| Spring flowers and cycling | Mar-Apr | Rapeseed blooms, mild temperatures, green countryside |
Whatever month you choose, the pattern is the same: mornings are better than afternoons, and flexibility beats a rigid plan. If you are still weighing the seasons, our best time to visit guide approaches the same question from an itinerary angle, and the packing list turns whichever month you pick into a concrete kit.
The difference between a comfortable day and a miserable one is often what you carry. The same month can feel very different on a karst ridge, a riverbank, or a flooded terrace path.
| Season | What to pack | Why it matters |
|---|---|---|
| Spring (Mar-May) | Light layers, packable rain jacket, quick-dry trousers, light fleece | Warm days but sudden showers; mist and dew in the mornings |
| Summer (Jun-Aug) | Breathable clothing, sun hat, strong sunscreen, insect repellent, umbrella | Heat, humidity, afternoon storms, mosquitos near water |
| Autumn (Sep-Nov) | T-shirt plus light jacket, comfortable walking shoes, sunglasses | Mild days, cool evenings, clearest skies |
| Winter (Dec-Feb) | Warm mid-layer, light down or fleece, waterproof shell, warm socks | Damp cold; indoor heating is limited |
Year-round essentials include a refillable water bottle, a power bank, and comfortable walking shoes with grip. In the rainy months, a proper rain jacket beats an umbrella on bikes, bamboo rafts, and terrace paths. In winter, layers handle the damp chill far better than one heavy coat.
Guilin rarely sees dangerous weather, but the subtropical climate can produce disruptive conditions. Knowing the risks helps you adjust rather than cancel.

Source & verification: Figures are long-term monthly averages for the Guilin region and vary year to year; check a current forecast before travel, especially during typhoon season.
October and November are the safest choices: comfortable temperatures around 18-26 C, the lowest rainfall of the year, and clear air. Late September is nearly as good and slightly warmer.
Rain builds from April and peaks in May and June, when monthly rainfall can exceed 300 mm. Expect frequent heavy showers rather than all-day rain, plus high humidity and occasional flooding in low areas.
July and August average 26-33 C with high humidity, which makes it feel hotter than the number suggests. Afternoon thunderstorms are common, and this is also typhoon season for the wider region.
Snow is rare in the city - an occasional light fall in January at most. The higher elevations around Longji see snow more often, and a dusting on the terraces is a genuine, if uncommon, winter sight.
Two peak moments: May and early June, when the terraces are flooded and mirror the sky, and late September to mid-October, when the rice turns golden before harvest. Winter and spring are bare by comparison.
Layers. Daytime highs sit around 8-15 C, but the damp air and lack of heating indoors make it feel colder. A warm mid-layer and a light waterproof shell handle most days.
Autumn is the safe answer; spring trades reliability for atmosphere.
