September and April are the two months where Beijing actually cooperates. September runs 28.0°C / 82.4°F by day, drops to 18.8°C / 65.8°F at night, and gets just 19.8mm of rain across 4 days — the summer heat has broken but the city hasn't turned cold yet. April is cooler at 23.7°C / 74.7°F high and 11.1°C / 52.0°F low with only 15.2mm over 3 days, which is the driest warm month of the year. Avoid July at all costs: 251.5mm of rain across 17 days at 32.6°C / 90.7°F is the single worst combination Beijing produces.

The best months: September, then April and May

September is the strongest month on the table. A 28.0°C / 82.4°F high is warm enough for short sleeves all day, and the 18.8°C / 65.8°F low means evenings on a rooftop or walking back from a hutong dinner are comfortable in a light layer. The rain figure is what makes it: 19.8mm over 4 days. That's roughly 5mm per rainy day — one brief shower, not a washout. Compare that to July's 251.5mm and you're looking at less than 8% of the rainfall, in a month that's only 4.6°C cooler by day.

The practical consequence: you can plan the Great Wall for a specific date in September and it will probably hold. In July you cannot. Mutianyu and Jinshanling are exposed ridgeline walks with stone steps — 4 rainy days out of 30 means you have room to reschedule; 17 out of 31 means you're gambling.

April is the dry-and-mild option. 23.7°C / 74.7°F high, 11.1°C / 52.0°F low, 15.2mm over 3 days. That daily swing of 12.6°C is the thing to plan around — a t-shirt at 2pm in the Forbidden City courtyards, a real jacket by 8pm. April is the driest month with genuinely pleasant temperatures, and 3 rainy days is close to a guarantee of clear itineraries.

May is warmer and wetter but still solid. 26.6°C / 79.9°F high, 15.6°C / 60.1°F low, 72.4mm over 7 days. Seven rainy days is roughly one in four, and 72.4mm spread across them averages about 10mm each — noticeable, umbrella-required rain, but not the sky-emptying kind. May's advantage over April is the night: 15.6°C / 60.1°F versus 11.1°C / 52.0°F means you stop needing a jacket after dark.

The months to avoid: July, August, and the deep-winter block

July is the clearest "no" in the data. 251.5mm over 17 rainy days, with a 32.6°C / 90.7°F high and a 24.5°C / 76.1°F low. Two things are happening at once. First, more than half the days in the month see rain. Second, the low never drops below 24.5°C / 76.1°F — the city does not cool off overnight, so the heat is cumulative rather than something you recover from while you sleep.

The 251.5mm across 17 days works out to roughly 15mm per rainy day, which is heavy. That's the East Asian monsoon pattern: hot, humid morning, sky goes dark around 3–4pm, an hour of serious downpour, then it clears. It is not gray drizzle from dawn to dusk. That matters for planning — a July trip isn't unusable, but it means front-loading outdoor sights into the morning and keeping the Capital Museum or a Sanlitun mall as the afternoon fallback.

August is July with the intensity dialed down. 30.0°C / 86.0°F high, 22.9°C / 73.2°F low, 177.5mm over 11 rainy days. Still 2.6°C cooler by day and six fewer rainy days than July, and 74mm less rain. If you're locked into a summer trip by school holidays, late August beats any part of July.

June is the heat month, not the rain month. 33.4°C / 92.1°F is the highest reading on the entire table — hotter than July — but rainfall is only 58.6mm over 6 days. June is dry heat before the monsoon properly arrives. It's the month where the Great Wall is genuinely dangerous if you go unprepared: full sun, no shade, steep stone, and a 22.6°C / 72.6°F overnight low that means you start the day already warm.

Winter is cold and bone-dry, which is a different problem. January highs reach 2.8°C / 37.0°F with lows at −4.7°C / 23.5°F and just 1.4mm of rain over 0 days. February is 4.9°C / 40.8°F high, −4.7°C / 23.5°F low, and 0.0mm of rain. December: 3.2°C / 37.8°F high, −4.6°C / 23.7°F low, 3.8mm over 2 days. These aren't rainy months — they're arid ones. Three straight months where the low sits below −4.5°C / 24°F and precipitation is essentially nil.

The reason to think twice about winter isn't rain, it's exposure. Beijing sits on a plain with wind coming off it, and outdoor sightseeing here is largely open-air: the Forbidden City is a mile of unheated courtyards, the Temple of Heaven is a park, and the Wall is a ridge. A −4.7°C / 23.5°F January morning on Mutianyu is a very different day than the same temperature spent between shops.

Shoulder season: late March, October, and November

March is the front-end shoulder. 15.5°C / 59.9°F high, 4.1°C / 39.4°F low, 13.5mm over 4 days. That's a 11.4°C daily swing on a base that's fundamentally chilly — comfortable for walking in the afternoon, cold at both ends of the day. The upside is that 13.5mm across 4 days is one of the driest readings of the year, and March sits before the April–May peak season.

October is the interesting one. 16.3°C / 61.3°F high, 9.2°C / 48.6°F low — pleasant walking weather — but 90.1mm over 9 days, which is the third-wettest month on the table. That's a real drop from September: temperatures fall 11.7°C and rainfall jumps from 19.8mm to 90.1mm in a single month. If you're choosing between September and October, September wins on both axes. October's argument is price and crowds, not weather.

November is the underrated pick. 11.9°C / 53.4°F high, 2.6°C / 36.7°F low, and only 7.2mm over 1 day. One rainy day in the month. It's cold — a proper coat month, and mornings near freezing — but it is almost certainly going to be clear, and it's outside every peak window. If dry weather matters more to you than warmth, November delivers 29 dry days.

What each season actually means on the ground

Spring (March–May). Layers, and specifically a jacket you can carry. The March swing is 11.4°C between high and low; April's is 12.6°C. You will put a jacket on and take it off twice a day. Rain gear is nearly optional — 3 to 4 rainy days in March and April — but May's 7 days warrant a packable shell. This is the season for the long outdoor days: Wall hikes, the Summer Palace lake circuit, Jingshan Park at sunset.

Summer (June–August). Sun protection first, rain gear second, and a schedule that respects the afternoon. June's 33.4°C / 92.1°F with only 6 rainy days means hat, sunscreen, and more water than you think. July and August flip that — 17 and 11 rainy days respectively — so a compact umbrella comes out and the afternoon slot goes to something indoors. Overnight lows of 24.5°C / 76.1°F in July and 22.9°C / 73.2°F in August mean you'll want breathable fabrics; cotton stays wet.

Autumn (September–November). The widest range of any season, from September's 28.0°C / 82.4°F to November's 2.6°C / 36.7°F low. September packs like summer minus the rain gear. October needs a mid-layer plus an umbrella for those 9 rainy days. November needs a proper coat but essentially no rain protection — 7.2mm over 1 day.

Winter (December–February). Insulated coat, gloves, hat, and thermal base layer, because you'll be outdoors in −4.7°C / 23.5°F for hours at a time. Skip the umbrella entirely: February recorded 0.0mm and January 1.4mm. Skip waterproof boots too — buy warm ones instead. Indoor heating in Beijing is strong, so the layering system needs to come off fast when you step into a restaurant or the subway.

FAQ

What is the single best month to visit Beijing?

September. It combines a 28.0°C / 82.4°F high with only 19.8mm of rain over 4 days — warm enough for outdoor days, dry enough that your plans hold. April is the runner-up at 23.7°C / 74.7°F and 15.2mm over 3 days, slightly drier but noticeably cooler, especially at night (11.1°C / 52.0°F versus September's 18.8°C / 65.8°F).

Is Beijing unbearable in summer?

June is hot and dry — 33.4°C / 92.1°F but just 58.6mm over 6 days — so it's manageable with sun protection and an early start. July is the real problem: 251.5mm over 17 days at 32.6°C / 90.7°F, with an overnight low of 24.5°C / 76.1°F that never lets the city cool down. The rain arrives as concentrated afternoon downpours rather than all-day gray, so schedule outdoor sights before noon. August is the better half of high summer at 30.0°C / 86.0°F and 177.5mm over 11 days.

How cold does Beijing actually get in winter?

January and February both bottom out at −4.7°C / 23.5°F, with December at −4.6°C / 23.7°F. Daytime highs stay low too — 2.8°C / 37.0°F in January, 4.9°C / 40.8°F in February, 3.2°C / 37.8°F in December. What makes it demanding isn't the number but the exposure: the Forbidden City, the Temple of Heaven, and the Great Wall are all open-air, so you're outside in those temperatures for hours. The compensation is that winter is bone-dry — February recorded 0.0mm of rain and January just 1.4mm over 0 days.

Do I need to pack rain gear for Beijing?

It depends entirely on the month, more than for most cities. July needs it (17 rainy days), August needs it (11 days), October needs it (9 days), and May warrants a packable shell (7 days). Everything else is close to optional: January, February, November, and December total 1, 0, 1, and 2 rainy days respectively. If you're visiting between November and February, use that suitcase space for a warmer coat instead.
