August is a decent shoulder option for Gdansk: fewer crowds, some trade-offs. Expect daytime highs around 23°C, nights near 14°C and roughly 8 rainy days across the month. Still the peak at around 23C, with the St Dominic's Fair running into early August and Sopot at its busiest for beach and nightlife. The Baltic stays cool to swim in even now; come for the buzz, but reserve rooms and boat trips well ahead.

With highs around 23°C, August is outdoor weather: prioritize viewpoints, parks and long walks.
The Long Market (Dlugi Targ)
TipThis grand pedestrian square runs between the Golden Gate and the Green Gate, past Neptune's Fountain, Artus Court and the ornate Golden House, and it is free and always open. Come at around 8am for photos of the empty gabled facades before the tour groups and the amber sellers set up, and skip the terrace cafes here, which charge the highest prices in the city; eat a block back instead.
St Mary's Church
TipThe largest brick church in the world holds a 15th-century astronomical clock and a tower you can climb. Entry to the nave is free with a small suggested donation, but the tower charges a few zloty and means around 400 steps up a tight spiral, so go early on a clear day for the view over the red roofs; it is a working church, so dress modestly and avoid Sunday services.
Westerplatte
TipThis peninsula is where the first shots of World War II were fired on 1 September 1939, now an open-air memorial of ruins and a tall monument. It is free and always open; the nicest way there is the tourist boat from the Motlawa jetties, about an hour each way, so buy a return and check the last sailing back, or take bus 106 and 138 if the boats have stopped for the season.
Oliwa Cathedral
TipThe Gothic cathedral in leafy Oliwa, north of the centre, is famous for its enormous Baroque organ of over 7,000 pipes. Entry is free, but the draw is the short organ recital, held several times a day in summer and less often in winter, so check the posted schedule at the door; take the SKM train to Gdansk Oliwa and walk about ten minutes through the park.
