Kunming is known as the “City of Eternal Spring”, yet its climate is more changeable than expected with a large diurnal temperature variation.Located in the central Yunnan-Guizhou Plateau at about 1,890 meters, it features a low-latitude plateau monsoon climate: small annual temperature range, large daily temperature gap, distinct wet and dry seasons, and strong ultraviolet radiation.Climatologically, Kunming is a “summer-free” city with only spring, autumn and winter. Spring and autumn last 295 days a year, accounting for 80.8% of the year, keeping flowers blooming all year round.Tourists still need to understand its real weather to pack properly and enjoy a more comfortable trip.
The Actual Weather in Kunming: Diurnal Temperature Variation & Wet and Dry Seasons
The most prominent features of Kunming’s weather can be summarized into the following three points:
- Large diurnal temperature variation: In a single day, it may feel warm or even hot in the afternoon with abundant sunshine, but the temperature drops rapidly after sunset. The diurnal temperature range can reach 12℃ to 20℃ in winter, and 4℃ to 10℃ in summer. A local saying goes, “Four seasons in one day”, which is a vivid description of this phenomenon. Tourists are advised to wear removable multi-layered clothes when going out in the morning to cope with temperature changes at any time.
- Distinct wet and dry seasons: Annual precipitation is mainly concentrated in the rainy season from may to october, during which the rainfall accounts for about 85% of the whole year. There is plenty of rain in the rainy season, but most are showers in the afternoon or evening, which come and go quickly, and the air becomes even fresher after rain. November to the next april is the dry season, with sunny and sufficient sunshine; there are an average of about 20 sunny days each month, and the rainfall only accounts for 3% to 5% of the whole year.
- Intense ultraviolet radiation: Due to its location on the plateau, the ultraviolet radiation intensity in Kunming is much higher than that in plain areas. Even on cloudy days or in winter, the ultraviolet index may reach the “excessive level”. Many first-time visitors ignore this and end up with sunburned skin after a day out. This is not an exaggeration, but a real lesson for many people who have been here. It is recommended to choose sunscreen with SPF 30 or above and reapply it every 2 to 3 hours.

Detailed Analysis of Kunming’s Weather in Four Seasons
Spring (March to May): Warm and Dry with Strong Winds
Temperature range: The average temperature is about 9℃ to 22℃ in march and rises to around 15℃ to 26℃ in may. According to meteorological data, spring in Kunming starts around February 9 and lasts about 117 days.
Weather features: Spring is one of the most pleasant seasons in Kunming, with temperatures warming up gradually, abundant sunshine in the daytime and a warm and comfortable feeling. It is also the golden period for flower viewing—cherry blossoms and Chinese flowering crabapples in Yuantong Mountain are in full bloom from late february to mid-march; the thousand-mu pear orchard in Chenggong Wanxichong ushers in the pear flower festival in mid-march; jacarandas on Jiaochang Middle Road turn the street into a “Monet’s Oil Painting Avenue” in april.
Points to note:
- Obvious temperature difference between morning and evening; it may be only about 4℃ in the early morning of march, so a light coat is a must.
- Strong winds and low air humidity can easily cause dry skin; moisturizing skin care products and a thermos cup are practical supplies.
Summer (June to August): Cool and Rainy, a Summer Resort
Temperature range: The maximum daytime temperature is usually 25℃ to 26℃, rarely exceeding 31℃; it drops to around 17℃ to 18℃ at night. According to climatological standards, Kunming rarely meets the summer standard in most years and is almost an “area without summer”.

Summer is the rainy season, with rainfall accounting for more than 60% of the whole year; the rainfall is the heaviest in august, and short showers often occur in the afternoon or evening.
Practical reminders:
- Carry a foldable umbrella with you; the air is particularly fresh after rain and the temperature is more comfortable.
- For clothes, short-sleeved tops, cropped pants and sandals are all acceptable, but a light long-sleeved coat is a must—on the one hand, to cope with the temperature drop in the evening, and on the other hand, it can also be used when the air conditioning is strong indoors.
- If you want to avoid the rain or arrange indoor activities, the Yunnan Provincial Museum and Yunnan Military Academy are good choices.

Travel Notes Related to Kunming’s Weather
Sun protection is a serious matter, not a casual reminder
Kunming has a high altitude and thin air, with extremely strong ultraviolet penetration. Many tourists think that sun protection is not needed in winter or on cloudy days, but their skin turns red and stings after half a day. It is recommended to choose sunscreen with SPF 30 or above and reapply it every 2 to 3 hours. In addition to chemical sun protection, physical sun protection is also important—wearing a wide-brimmed hat, sunglasses and light long sleeves can effectively block ultraviolet radiation.
Moisturizing and hydrating cannot be taken lightly
The plateau climate is dry, especially in the dry season (november to april) when the humidity is often lower than 30%. In addition to drinking plenty of water, skin care should be strengthened. Carry a moisturizing spray with you, apply a facial mask at night, and put a glass of water in the hotel room to increase humidity. These small life tips can avoid the troubles of a dry and sore throat and dry skin.
Carrying an umbrella with you is a habit in the rainy season
During the rainy season from may to october, although it does not rain all day, afternoon thunderstorms are quite frequent. It is recommended to put a light foldable umbrella or raincoat in your backpack for emergencies. The road surface is slippery on rainy days, so it is safer to wear non-slip shoes.
There is no need to worry too much about altitude sickness
Kunming has an altitude of about 1,890 meters, and severe altitude sickness generally does not occur. However, tourists from low-altitude areas may still feel slight discomfort, such as dizziness and shortness of breath. It is recommended to rest properly after arrival, avoid strenuous exercise and drink plenty of water. If you have cardiopulmonary-related diseases, it is best to consult a doctor before departure. Carry common cold medicine and gastrointestinal medicine with you for emergencies.

Add clothes in the morning and evening to prevent colds
The biggest trap of Kunming’s weather is the large temperature difference. You may sweat a lot from playing during the day, and it is easy to catch a cold when the wind blows in the evening. It is recommended to carry a light coat with you and put it on before the sun sets, instead of waiting until you feel cold to add clothes.
