Gdańsk is a Baltic port city where colorful Dutch-Renaissance townhouses line cobblestone streets along the Motława River, and amber shops glow on nearly every corner. This is the city where World War II began at Westerplatte and where dockworkers launched the Solidarity movement that helped topple communism across Eastern Europe. Walk the Long Market, climb the tower of St. Mary's Church (one of the world's largest brick churches), and explore world-class museums before settling into a waterfront table for pierogi and a glass of Goldwasser, the city's signature gold-flecked liqueur.
Your best window runs from late May through the end of September, when Gdańsk's long Baltic days, pleasant temperatures, and packed events calendar all align. Summer is the clear peak: highs average 70.4°F (21.4°C), the sun doesn't set until well after 9pm in June, and the city fills with open-air festivals. St. Dominic's Fair takes over the Old Town from late July into mid-August, drawing millions of visitors to browse amber jewelry, regional crafts, and Polish street food. The Open'er music festival in neighboring Gdynia typically lands in early July. September holds up as a strong shoulder month with comfortable weather and noticeably thinner crowds. If you're drawn to Christmas markets, late November through late December is a compelling secondary window, though you'll trade warmth for festive atmosphere and mulled wine.
Spring in Gdansk, Poland
Gdańsk thaws slowly in spring. March still carries the chill of winter, but by May the city's parks and riverside walkways come alive. This is the season to explore the Museum of the Second World War and the European Solidarity Centre without summer queues. The Solidarity Centre, housed in a striking rust-toned building that echoes the shipyard cranes around it, tells the story of the movement that launched from these very docks. Spring crowds are thin, and accommodation prices drop to their lowest, making it an appealing window for travelers who prefer a quieter pace.
Temperatures climb gradually: seasonal highs average 52.7°F (11.5°C) with lows around 41°F (5°C), so mornings along the Motława River can feel brisk. Layers are essential. By late April, daylight stretches past 14 hours, giving you ample time to wander Mariacka Street's amber galleries and spot the gargoyle waterspouts (locals call them pukers) that come alive on rainy days. Showers are infrequent this time of year, with roughly one to three wet days per month.
May Day and Constitution Day fall in early May, and some shops and museums may close for these public holidays, so plan around them. A day trip to Malbork Castle, the world's largest brick castle and a UNESCO World Heritage Site about an hour away by train, is especially enjoyable before summer tourist traffic picks up. Pack a windbreaker and comfortable walking shoes: the Baltic breeze can be persistent even on sunny afternoons.
Summer in Gdansk, Poland
Summer is when Gdańsk fully delivers on its promise as a Baltic destination. The city's biggest draw is St. Dominic's Fair, a tradition stretching back to 1260 that fills the Old Town with hundreds of stalls selling amber, regional crafts, smoked cheese, and street food from late July through mid-August. Millions of visitors pass through during these weeks. In neighboring Gdynia, the Open'er music festival typically takes over an old airfield in early July, bringing major international headliners to the Tricity area. River cruises along the Motława to the Westerplatte peninsula run at full capacity, and the beaches at Jelitkowo and Brzeźno fill with sunbathers.
Seasonal highs average 70.4°F (21.4°C) with lows of 58.3°F (14.6°C), comfortable enough for full days outdoors. Mid-July brings the warmest stretch, when highs reach 73.8°F (23.2°C) and overnight lows stay near 60.4°F (15.8°C). Daylight is extraordinary: in June, the sun doesn't set until after 9pm, giving you nearly 17 hours to explore. July is one of the rainier months, so expect afternoon showers on roughly two to four days, but they tend to pass quickly. A light rain jacket stashed in your day bag will keep you moving.
This is peak tourist season, and accommodation prices reflect it. Book well ahead if your visit overlaps with St. Dominic's Fair or Open'er. The old Shipyard District behind the Solidarity Centre has been transformed into a creative quarter with murals, pop-up galleries, and open-air bars built from shipping containers, perfect for warm summer evenings. For a quieter escape, take the SKM commuter train north to Oliwa and catch one of the free organ concerts at Oliwa Cathedral, where the instrument's ornate carved angels move as the music plays.
Fall in Gdansk, Poland
September is arguably the best-kept month in Gdańsk's calendar. The summer crowds thin out considerably, but temperatures remain comfortable: seasonal highs average 55.1°F (12.8°C) and lows sit at 44.6°F (7°C). Early September still holds warmth from the fading summer, and you can walk the Long Market or browse the Amber Museum in relative peace. The Motława waterfront takes on a golden quality in the softer autumn light, making it a photographer's dream.
As October arrives, daylight shortens noticeably, dropping to around 10.5 hours, and the weather cools enough to make a warm jacket necessary. Showers pick up to roughly two to four days per month. All Saints' Day in early November is a significant observance in Poland: cemeteries glow with thousands of candles, and some attractions may have reduced hours. By mid-November, the days shorten further and temperatures dip, but Gdańsk's Christmas market opens in late November, transforming Coal Market Square into a festive village of wooden stalls, gingerbread, mulled wine, and handmade crafts. Accommodation is slightly higher than spring but below summer peaks.
Fall rewards visitors who appreciate culture without the crush. The European Solidarity Centre and the Museum of the Second World War are easier to visit at your own pace, and restaurant terraces stay open into October with blankets and heaters. Pack layers you can peel off during a sunny afternoon and add back once the Baltic wind picks up at dusk.
Winter in Gdansk, Poland
Winter in Gdańsk is cold, dark, and quiet, but the city's Christmas market has earned a reputation as one of the best in Europe. Typically running from late November through late December, it fills Coal Market Square with stalls offering pierogi, grilled oscypek cheese, bigos stew, and steaming cups of grzaniec, Poland's mulled wine. Handmade amber jewelry, wooden ornaments, and Bolesławiec pottery make for distinctive gifts. A Venetian carousel, an ice skating rink, and craft workshops in the Great Armoury round out the festive scene.
Expect to bundle up. Seasonal highs average only 36.5°F (2.5°C) with lows dropping to 28°F (-2.2°C), and snow can accumulate, particularly in February when depths peak. Daylight is limited: December offers barely seven hours of light, so plan your outdoor sightseeing around midday. Precipitation falls as rain, sleet, or snow on roughly two to four days per month. Christmas Eve, Christmas Day, and St. Stephen's Day see widespread closures, so stock up on essentials beforehand.
Tourist numbers hit their lowest in winter, meaning museum visits are unhurried and accommodation deals are available. The Museum of the Second World War, mostly underground and climate-controlled, is an ideal winter activity that easily fills three hours. Warm waterproof boots with good traction are a must on icy cobblestones, and thermal layers under a heavy coat will keep you comfortable between heated cafes.

Travel Tips & Safety for Gdansk, Poland
Gdańsk's compact Old Town is easy to explore on foot, but for reaching neighborhoods like Oliwa or the beach district of Jelitkowo, the SKM commuter train and the city's tram and bus network are efficient and affordable. The Jakdojade app helps with route planning across the entire Tricity area. Trains also connect Gdańsk to Sopot and Gdynia in under 30 minutes, making day trips simple.
Gdańsk is generally a safe city for travelers. Keep normal precautions in crowded tourist areas like Długi Targ and the Christmas market, where pickpocketing can occur. Cobblestone streets are beautiful but uneven, so sturdy shoes help prevent stumbles, especially after rain or snow when surfaces get slippery.
Poland uses the złoty (PLN), and while card payment is widely accepted, carrying some cash is useful at market stalls and smaller vendors. Tipping around 10% at restaurants is customary. The tap water is safe to drink throughout the city.
