The best time to visit Dalian is September to early October, when daytime highs sit at 17 to 24°C (63 to 75°F), rainfall drops to 30 to 60 mm, and skies stay clear. June to August is beach season but also the rainiest and most crowded stretch, and December to February is cold and windy, with highs near 0°C (32°F). This guide breaks the year down by weather, prices, crowds, and events, as part of the broader Dalian travel guide.
Best Time to Visit Dalian for Weather
For mild, dry weather, book between mid-September and mid-October. September averages 24°C (75°F) by day and 16°C (61°F) at night, October 17°C (63°F) high and 9°C (48°F) low, and both months stay below 60 mm of rain. Late April and May are a close second, with highs of 15 to 20°C (59 to 68°F) and 32 to 45 mm of rain, plus the cherry blossom season in Lushun. The full month-by-month breakdown is in the Dalian weather by month article.
Best Time to Visit Dalian for the Beach
Swimming season runs from late June to early September, when the sea warms to 18 to 24°C (64 to 75°F). August is the warmest month for the water at 24°C (75°F), but it is also the wettest, with 170 mm of rain, and the most crowded, since Chinese domestic tourists flood the coast during the summer school holiday in July and August. Aim for late June or early September to catch warm water with fewer crowds. See the things to do in Dalian guide for the best beaches and bays.
Best Time to Visit Dalian for Low Prices
Hotel rates in Dalian drop 30 to 40 percent from November through March, outside the peak summer and National Day windows. A mid-range room that runs CNY 450 to 650 a night in August can fall to CNY 280 to 400 in January and February. Avoid the two week-long Chinese holidays, the first week of October (National Day) and the Lunar New Year in late January or February, when domestic travel spikes and rates climb. For specific hotels at each budget level, use the where to stay in Dalian page.
Best Time to Visit Dalian for Fewer Crowds
July and August draw the biggest crowds, both from Chinese families on school holidays and from visitors escaping the heat of Beijing and Shanghai, which sit 5 to 8°C hotter. Attractions like Laohutan Ocean Park and Discovery Kingdom queue for 40 minutes or more on summer weekends. Weekdays in May, June, September, and October are far quieter, and winter is almost empty apart from the ski and hot-spring crowd at nearby resorts. Check the Dalian neighborhoods guide to spread your sightseeing across districts.
Best Time to Visit Dalian for Events
The Dalian International Beer Festival fills Xinghai Square for about 20 days in late July and August, the city’s biggest single event. The International Fashion Festival opens in September, the International Marathon and Walking Festival run in May, and the Lushun Cherry Festival runs through June. The annual calendar is mapped out in the Dalian events and festivals article, which lists dates, venues, and what to expect.
Best Time to Visit Dalian: Months to Avoid
Skip December through February unless you enjoy cold coastal wind; highs hover at 0 to 3°C (32 to 37°F) and the sea breeze makes it feel colder. July and August bring the heaviest rain, 140 to 170 mm a month, and peak domestic crowds, so they are the worst months for anyone who dislikes humidity and queues. If you have to travel in summer, go in late June or early September. For practical arrival details and airport transport, see the Dalian travel tips article.
