Overview of Harbin’s Summer Climate
Summer in Harbin brings mild to warm temperatures, long daylight hours, and frequent rainfall. As the season goes on, you’ll get more clear skies, but humidity and short bursts of rain are still pretty common.
General Climate Characteristics
Harbin sits in a continental monsoon zone, which shapes its summer climate. You can expect average daytime highs around 78°F (25–26°C), with peaks near 81°F (27°C) in early July.
Nights usually cool off to about 61°F (16°C), so evenings feel a lot more comfortable. Rain falls steadily, with about one in three days seeing measurable precipitation.
Late July can get muggy, but early summer feels less humid. Winds mostly come from the south, averaging 8–10 mph. By August, they calm down a bit.
You’ll get more than 15 hours of daylight near the June solstice. Sunsets start to shift earlier by late August.
These long days and moderate warmth make outdoor activities pretty comfortable—just watch out for the rain.
Seasonal Weather Patterns
June kicks off with mild warmth and plenty of clouds. By July, temperatures climb to their highest, and rainfall peaks.
The chance of a “wet day” stays around 34%, but the heaviest 31-day average rainfall—about 4.4 inches—happens in late July.
Humidity rises through mid-summer. By the end of July, you might run into muggy conditions on lots of days, especially during calm, damp evenings.
Clear skies show up more often after mid-August, so late summer feels drier and brighter. Winds keep decreasing, and August feels calmer than June.
With less cloud cover, you’ll get clearer views of the city and countryside. The growing season goes strong, and crops thrive in the warmth and rain.
Comparison to Other Seasons
Harbin’s summer feels like a whole different world compared to its long, frigid winters. In January, daily highs often stay below freezing, but in July, they shoot up to the upper 70s°F.
That’s a seasonal swing of over 90°F (50°C). Spring and autumn are quick transitions.
Spring warms up fast but can be dry and windy. Autumn cools just as quickly, with frost sometimes showing up by late September.
Unlike winter’s snow and ice, summer is the wettest stretch of the year. Rain pours down from June to August, while winter barely sees any precipitation.
The combo of warmth, rain, and long days makes summer the best time for outdoor travel in Harbin.

Daytime and Nighttime Variations
You’ll spot a clear difference between daytime and nighttime temperatures. Afternoons often climb above 26°C (79°F), but evenings cool down quickly, giving you a break from the heat.
This is pretty typical for northern China, where nights stay cooler even in summer. If you’re planning to be outside, mornings and evenings are usually the most comfortable.
Midday can get sticky, especially when it’s humid. Pack light clothes for the day and maybe a light jacket for when the sun goes down.
Because of these shifts, you might not need heavy air conditioning indoors. Sometimes, it’s nice enough at night to just crack a window.
Temperature Extremes
While most summer days are moderate, you’ll occasionally hit extremes. The hottest days can reach 33–35°C (91–95°F), especially in late July.
These heat waves don’t last long but can feel intense when humidity is high. At night, temperatures rarely drop below 12–14°C (54–57°F).
Harbin stays cooler at night than southern cities, where it can stay hot and muggy even after dark.
Heat waves aren’t as common here as in central or southern China, but they do happen. When it gets really hot, staying hydrated and avoiding the midday sun is a smart move.
Rainfall and Humidity During Summer

Summer is definitely the wettest time of year, while the rest of the seasons stay much drier.
Humidity Trends in Summer
Humidity creeps up steadily from late spring into summer. By June, relative humidity often hits around 65%, and it climbs to about 75% or higher in July and August.
That’s mostly because of the extra rain and warmer air holding more moisture. In July, when daily highs hit 27–29°C, you’ll really feel it.
Heat and humidity together can make afternoons feel hotter than what the thermometer says. Mornings tend to feel stickier, while afternoons might get a little relief when winds pick up or rain clears the air.
Still, that damp feeling sticks around for most of the summer.
Number of Rainy Days
You’ll get more rainy days in summer, too. June usually sees 10–12 rainy days, July peaks with about 14–16 days, and August isn’t far behind with 12–14 days.
Rain usually comes in spurts, not all day long. Showers are often quick, with sunshine popping back out in between.
Sometimes, though, downpours hit hard enough to mess with outdoor plans. Snow doesn’t show up in summer, so all the precipitation is rain.
If you’re visiting, especially in July, bring an umbrella or raincoat and expect wet weather.
Sunshine Hours and Daylight in Summer
Harbin’s summers bring long, bright days. Sunshine hours jump compared to winter, and daylight stretches well into the evening.
Average Daily Sunshine
During summer, Harbin gets about 8 to 10 hours of sunshine per day. May is actually the sunniest month, with around 265 total hours of sunlight, but June through August are still pretty bright.
Clouds hang around more in early June, but by July and August, you get clearer conditions and more reliable sunny days.
For context, Harbin averages about 2,575 hours of sunshine a year. That’s more than cities like Vancouver or Manchester, but not as much as Lisbon or Perth.
So, for its latitude, Harbin’s summer is surprisingly sunny.
Day Length Changes
Daylight changes a lot through summer. Around the solstice in late June, you’ll see over 16 hours of daylight—that’s a lot of time to be outside.
In July, days start to shorten a little, but evenings are still long and bright. By August, daylight drops to about 14 hours a day.
These long evenings are great if you want to explore the city, visit parks, or catch a festival. Mild to warm temperatures make those late nights outside much more enjoyable.
Wind and Atmospheric Conditions
During summer, Harbin brings light winds and steady air pressure, which add to the humid and warm feel. Storms can whip up short bursts of stronger gusts, but most days stay calm with stable weather.
Typical Wind Speeds
Winds in Harbin during summer are usually mild. You’ll get average speeds around 3 mph, which isn’t enough to mess up your plans.
This calm pattern makes walking, cycling, and hanging out outside pretty pleasant. The windiest months actually happen in spring, especially March through May, when speeds can reach about 9 mph.
By summer, winds settle down. Sometimes thunderstorms in July and August bring brief gusts, but they pass quickly.
Most of the time, the air feels still, especially compared to coastal or mountain cities. With such light winds, air circulation is limited.
On humid days, that can make the heat feel even heavier, especially in crowded spots. Morning or evening activities feel more comfortable if you want to avoid the stickiness.
Air Pressure Patterns
Summer air pressure in Harbin stays pretty steady. Average readings are about 741 inHg, reflecting the city’s inland spot and moderate elevation of around 118 meters.
Stable pressure means you won’t see sudden weather swings like in places closer to the ocean. High humidity mixes with this steady pressure to create a heavy feel in the air.
You’ll notice this most in July, the wettest month. Rain often comes in short, intense bursts, thanks to moist monsoon air from the south.
Winter brings much stronger pressure systems, but summer’s patterns are less extreme. This stability means you get long stretches of warm, humid days, with only the occasional storm breaking things up.
If you’re traveling, you can usually count on predictable weather—just keep an eye out for those sudden showers.
