Baltic Sea water temperatures reach a swimmable 18–19°C in late July and August. Swimming before mid-June or after mid-September is possible but cold — a wetsuit or high cold-tolerance is advisable. The sea stays at around 17°C into September, which surprises many visitors expecting a very short swim season.
May and September: The Best-Value Travel Windows
July and August are Gdansk's peak months: warmest weather, longest daylight, but also the highest hotel prices (often 40–60% above shoulder season rates) and the longest museum queues. May and September offer almost identical sightseeing conditions — Old Town walking is perfectly comfortable at 17–18°C — but hotel rates in the Old Town typically drop from 350–500 PLN to 200–280 PLN per double room per night.
September has a further edge: Baltic water temperatures of 17°C still allow a swim in the sea, the summer events calendar (outdoor concerts, Długi Targ markets) runs into mid-month, and the city has visibly fewer coach-tour groups. If you are flexible on dates and not specifically chasing beach weather, September is the single best month to visit Gdansk.

Essential Packing Tips for Gdansk Weather
Packing smart for Gdansk means preparing for variable weather, especially during transitional seasons. Layering is always a good strategy, allowing you to add or remove clothing as temperatures change. Consider the specific month of your visit for targeted packing.
Waterproof outerwear is a year-round essential, given Gdansk's occasional rain. Comfortable, sturdy walking shoes are also crucial for exploring the city's cobblestone streets. Your footwear choice significantly impacts your comfort level.
In winter, Gdansk's cobblestones can turn icy after freezing rain. Waterproof ankle boots with a rubber grip sole are the single most important item to pack for a December–February visit.
Sun protection, like sunglasses and sunscreen, is important even in cooler months due to UV exposure. In winter, thermal base layers, a warm hat, gloves, and a scarf are non-negotiable. Find more useful travel advice on the Poland Wander blog.
