Spring Climate Overview in Dalian
Spring in Dalian shifts things from cold and dry to warmer and wetter weather. You’ll feel the temperatures rise, humidity climb, and rain show up more often as spring goes on, all thanks to the Bohai Sea and Yellow Sea surrounding the area.
General Spring Weather Patterns
Dalian sits at the southern tip of the Liaodong Peninsula, so the city feels that strong maritime influence. This keeps the climate milder than what you’d find farther inland in northeast China.
March starts out cool and breezy. By May, the air is warmer and more humid, and daylight lasts much longer.
Clouds show up more often as summer nears, with the skies getting noticeably more overcast.
Rainfall increases as spring moves along. Early on, you’ll get the odd light shower, but by late spring, wet days are more common. Roughly 40–50% of May days bring some rain.
The city’s coastal setting helps keep temperature swings in check. While inland spots might still get hit by cold snaps early in spring, Dalian’s weather stays steadier thanks to the nearby seas.
Temperature Trends from March to May
In March, daytime temperatures usually sit between 5°C and 10°C (41°F to 50°F), with colder nights. By April, highs get closer to 15°C (59°F), and May regularly sees 20°C to 24°C (68°F to 75°F).
Spring warms up month by month, so you’ll definitely notice the change. The temperature bumps up about 20°F (11°C) from early March to late May.
Nights warm up fast too. March nights can still flirt with freezing, but by May, lows usually stay above 12°C (54°F).
Cold snaps fade away after April, so late spring feels like prime time for being outside in Dalian.
Humidity and Wind Conditions
March starts off pretty dry, with muggy days being rare—just about 1%. By May, though, nearly 80% of days feel humid as warm air blows in from the Yellow and Bohai Seas.
That extra moisture makes late spring air feel a bit heavier, especially as temperatures rise.
Winds play a big part in the weather. Average speeds drop from around 15 mph in March to 12 mph in May.
Early spring winds come from the north and bring chillier air. By late May, southerly winds take over, carrying in moisture from the sea.
These shifting winds really shape the spring climate, mixing dry northern air with humid southern breezes.
Monthly Breakdown: March, April, and May
Spring in Dalian means steady warming, more daylight, and a slow uptick in rainfall. March mornings feel crisp, April afternoons turn mild, and by May, you’re looking at comfortably warm days. The land and sea both show clear signs of the season changing.
March Weather Details
March still hangs onto winter’s edge. Average daytime temperatures hover around 3–7°C (37–45°F), and nights can get close to freezing.
The ocean stays cold at 3°C (37°F), so coastal winds keep the air feeling brisk.
Rain is pretty minimal—about 12 mm over a handful of days. You’ll usually get 6–7 hours of sunshine, but the air is still dry.
If you’re heading outside, layers and a windproof jacket make sense. Early spring flowers peek out in parks, but lush greenery isn’t quite here yet. The city feels quieter than it does in busy summer.
April Weather Details
April brings a real change. Highs reach 15°C (59°F), and lows stay near 7°C (45°F). The air feels much milder, though evenings can still be cool.
Sea temperatures creep up to about 6°C (43°F)—still not swim weather, but the waterfront feels less biting.
Rainfall doubles compared to March, averaging 25 mm over 4–5 days. You’ll see more sunshine and a higher UV index, so a bit of sun protection is smart.
Parks and gardens burst with cherry blossoms and tulips, drawing more people out. Most days are clear, though spring showers pop up now and then to freshen the air. Carrying a light raincoat or umbrella just makes sense.
May Weather Details
By May, Dalian feels almost like summer. Highs hit 20°C (68°F), and lows hover around 12°C (54°F). The sea gets up to about 11°C (52°F)—still chilly, but you can tell beach season isn’t far off.
Rain picks up again, with about 47 mm over 6–7 days. The UV index jumps to 8, so sunscreen and hats become pretty important if you’re out and about.
You’ll notice longer days and a lot more greenery. Parks are packed with blossoms, and the coast buzzes with visitors. May is honestly one of the best months for walking tours, outdoor meals, and exploring Dalian’s coastline.
Precipitation and Sunshine in Spring
Spring in Dalian brings a mix of gentle rain, more sunshine, and shifting clouds. Temperatures and daylight both rise steadily, all shaped by the city’s spot along the Yellow Sea and Bohai Sea.
Rainfall Patterns and Amounts
Spring rain is moderate—nothing like the summer downpours. March stays pretty dry, with less than 15 mm of rain over just a few days. By April, totals climb to around 30–40 mm, and May usually brings 50–60 mm.
Most of the rain falls gently or steadily, not in heavy bursts. Snow’s rare after March, but you might see a stray flurry early in the season.
Rainy days get more common as spring goes on. March has just 3–4 wet days, while May averages about 7–8. This extra moisture greens up parks and coastal spots, making outdoor areas more vibrant by late spring.
Sunshine Hours and Day Length
Dalian sees more sun as spring rolls in. March brings about 6 hours of sunshine each day, and by May, you’ll get 8 hours or more. Late spring is honestly one of the brightest times of year.
Day length grows fast too. March days last 11–12 hours, while May stretches out to nearly 14. More daylight means more chances for coastal walks—think Xinghai Bay or those cliffs over the Yellow Sea.
The mix of warmer temps and longer days makes spring great for sightseeing and outdoor fun. May, in particular, feels especially pleasant, with warm afternoons and plenty of daylight to explore.
Cloud Cover and Visibility
Clouds build up through spring, especially in April and May. March skies are clearer, but late spring brings overcast or mostly cloudy days more than half the time. Moist air from the Bohai and Yellow Seas drives this change.
Even with more clouds, visibility usually stays solid. Coastal breezes clear out haze, and spring fog isn’t as common as in summer. When fog does roll in, it usually forms early and lifts by midday.
You’ll get a mix of sunny spells and cloudy stretches, but rarely any long gloomy periods. This balance keeps spring weather steady enough for outdoor plans, while still showing off the city’s coastal climate quirks.
Sea Temperatures and Coastal Influence
Spring in Dalian brings real changes to the sea and coast. The nearby waters play a big part in keeping temperatures moderate, shaping local weather, and creating little climate differences across the peninsula.
Average Sea Water Temperatures
The sea starts warming up after winter. In March, sea surface temperatures average 4–5 °C (39–41 °F). By April, you’ll see 9–10 °C (48–50 °F), and May usually reaches 14–16 °C (57–61 °F).
The water stays cooler than the air, so it takes longer for the coast to catch up to spring’s warmth.
For most visitors, swimming isn’t really an option until late May, but coastal walks feel great earlier. The cool water also keeps the shoreline air crisp, even on warmer days.
| Month | Avg Sea Temp °C | Avg Sea Temp °F |
|---|---|---|
| March | 4–5 | 39–41 |
| April | 9–10 | 48–50 |
| May | 14–16 | 57–61 |
Impact of Bohai Sea and Yellow Sea
Dalian sits between the Bohai Sea to the west and the Yellow Sea to the east and south. These two seas act like natural thermostats, softening the wild temperature swings you’d get further inland.
In spring, Bohai Sea winds can feel cool and damp, especially in March and early April. The Yellow Sea, being bigger, brings milder breezes as the season goes on.
Moist air moving inland raises humidity and helps spring vegetation grow. Sometimes, fog forms along the coast when warm air meets the cold sea—this happens a lot in April and May.
This double-sea setup gives Dalian a more balanced climate than inland cities at the same latitude.
Coastal Microclimates
The Liaodong Peninsula coastline creates some noticeable microclimates. Areas near the open Yellow Sea often warm up faster in late spring, while bays facing the Bohai Sea can stay cooler a bit longer.
Neighborhoods close to sheltered harbors get less wind, while exposed headlands stay breezy and cooler. These differences show up most in April, when inland spots feel warmer but the coast still clings to a chill.
If you’re planning outdoor time, location matters. A walk along Xinghai Bay in May feels mild, but you might still want a light jacket on the northern Bohai coast.
These local quirks are worth thinking about if you want to see both seaside and inland parts of Dalian in spring.
Spring Activities and Travel Tips
Spring in Dalian brings mild weather, blooming landscapes, and lots of outdoor things to do. You can check out coastal scenery, catch seasonal festivals, and visit cultural sites—but it’s smart to prep for cool mornings and warmer afternoons.
Best Time to Visit Dalian in Spring
Dalian’s spring runs from March to May. Early March still feels a bit cold, with highs near 7°C, but May warms up to around 20°C. Rain picks up too, from about 12 mm in March to nearly 50 mm in May.
April and May are the sweet spot for sightseeing. The air is mild, flowers are everywhere, and outdoor attractions are open and easy to get to. It’s also less packed than summer.
If you’re hoping to see cherry blossoms or tulip festivals, April is the best month. May gives you steadier weather for hiking, coastal walks, and park visits. These months hit that nice balance of pleasant temperatures and manageable rain.
Popular Outdoor Destinations
Spring brings a bunch of outdoor spots worth checking out. Longwangtang Sakura Garden really shines from early April to mid-May, when cherry blossoms blanket the park.
Labor Park sits right in the city center and holds spring flower events. You’ll see tulip displays and all sorts of flowers popping up there.
If you want coastal scenery, head to Bangchui Island. It mixes beaches, wooded hills, and some great sea views. Trails lined with acacia and seasonal flowers make it a nice pick for a light hike.
For an urban coastal walk, Binhai Road stretches for over 30 kilometers and links up several scenic spots.
Beaches like Xinghai Bay still feel too chilly for swimming in spring. But walking along the sand and grabbing some fresh seafood nearby is a good way to spend an afternoon.
Spring’s also a solid season to check out the local seafood markets. Prices usually dip compared to summer, so you might find a bargain or two.
Packing Recommendations for Spring
Dalian’s spring weather changes fast, so it’s smart to pack with layers in mind. You’ll want a light jacket or windbreaker for March and April. A sweater or hoodie comes in handy for those cooler evenings.
By May, lighter clothes work well during the day.
Bring comfortable shoes for all the parks and coastal trails. I’d throw in an umbrella or a light raincoat, since rain picks up toward late spring.
Sunglasses and sunscreen help too, because even when it’s mild, you get plenty of sunshine.
If you’re heading to gardens or the coast, a small backpack makes life easier. Toss in water, snacks, and an extra layer, just in case the weather flips between chilly mornings and warmer afternoons.

Dalian mixes coastal scenery, cultural sites, and city attractions. You’ll notice its maritime vibe and those historical influences all around.
You can wander natural coastlines, explore the peninsula’s landscapes, and experience a blend of modern city life with easy access to the outdoors.
Exploring Xinghai Bay
Xinghai Bay draws tons of visitors every year. You’ll find a wide, curved beach with urban development and open public spaces behind it.
Xinghai Square stands out here—it’s one of Asia’s biggest city squares and often hosts festivals and events.
The bay gives you a clear view of the sea and the nearby hills. In spring, the weather stays mild enough for long waterfront walks.
Breezes off the Yellow Sea keep things cool and comfortable, which I personally love.
You can pop into the Dalian Shell Museum or just stroll along the promenade. The mix of open water, landscaped areas, and cultural spots makes Xinghai Bay a practical choice for sightseeing and unwinding.
Liaodong Peninsula Attractions
The Liaodong Peninsula wraps around Dalian, facing both the Bohai Sea and the Yellow Sea. You can explore rocky shores, fishing villages, and some pretty scenic cliffs.
The peninsula’s geography makes it popular for day trips just outside the city.
Lushun (Port Arthur) sits at the southern tip and stands out for its history. Past naval battles and preserved military sites give it a lot of character.
You’ll also find museums and viewpoints that dig into its regional significance.
The peninsula’s spring climate feels cooler near the water and a bit warmer inland. That balance makes it great for hiking coastal trails or visiting fruit orchards just as they start to bloom in late spring.
