Tips for Planning Your Visit to Warsaw
You’ll have an easier trip if you prepare for Warsaw’s changing seasons, mix up indoor and outdoor activities, and figure out which attractions are worth it all year. Weather really shapes what you pack, where you go, and how you spend your days.
Packing Essentials for Each Season
Warsaw’s climate changes a lot, so your suitcase should match the season. In spring (April–June), bring a light jacket, umbrella, and comfy walking shoes since you’ll probably get some rain.
For summer (June–August), you’ll want breathable clothes, sunscreen, and a hat. Temperatures often hit 25–30°C (77–86°F), and the long days are perfect for being outside.
In autumn (September–November), the air gets cooler and sunsets come earlier. Pack layers, a medium coat, and waterproof shoes for the unpredictable rain.
Winter (December–February) means you’ll need a warm coat, gloves, scarf, and boots. Temperatures dip below freezing, and snow is common. If you’re planning to visit Christmas markets or ice rinks, thermal layers help a lot.
A small crossbody bag and a reusable water bottle are handy no matter when you visit.
Recommended Outdoor and Indoor Activities
Outdoor activities really depend on the season. In summer, you can check out open-air concerts in Łazienki Park or bike along the Vistula River. Spring and autumn work best for walking tours in the Old Town, when the weather’s just right.
In winter, it makes sense to focus on indoor spots. The Warsaw Uprising Museum and the Royal Castle offer rich history and keep you warm. Cafés are great for a cozy break from the cold.
On rainy days, try Warsaw’s art galleries or science museums. If you get a clear day, head outside for gardens, plazas, and street markets. Mixing indoor and outdoor plans means you won’t lose out if the weather changes suddenly.
Top Parks and Attractions for Every Time of Year
Łazienki Park stands out no matter the season. In summer, you’ll catch Chopin concerts and spot peacocks wandering around the gardens.
When autumn rolls in, the park lights up with those amazing fall colors. Winter covers everything in snow, making it a peaceful spot for quick walks.
The Old Town Market Square buzzes in summer with people eating outside. Once winter hits, the place turns magical with holiday lights everywhere.
If you’re around in spring, the Saxon Garden bursts into bloom and shady paths make for a calm stroll.
Locals love the Vistula Boulevards in summer, gathering for riverside picnics and just hanging out by the water.
You can always count on the Palace of Culture and Science. Head inside for exhibits or take in the city from the observation deck, rain or shine.
