Warsaw Weather in May

May weather in Warsaw

May feels mild rather than warm, with daytime highs around 19°C and nights near 9°C. You'll get long days for walking the Royal Route, exploring Łazienki Park or taking a Vistula riverside stroll. The parks are leafy, and outdoor cafés are pleasant when the sun's out.

Rain falls on about 13 days, so don't count on every afternoon staying dry. Keep a flexible plan for the Old Town: a shower is a good excuse to duck into the Royal Castle. May is warmer than April, but June is warmer still.

Holidays and events

May 3 is Constitution Day, a public holiday in Poland. Warsaw marks it with official ceremonies, especially around Castle Square. The holiday can bring extra visitors and closures, so check opening details if you're heading to a particular museum.

The annual Night of Museums usually takes place in May. Museums and cultural venues stay open late, and some offer free entry. If you hate crowds, choose a smaller museum instead of the most popular stops, such as the POLIN Museum.

Crowds and practical tips

May is a shoulder-season month: it's generally calmer than the summer peak, though the holiday weekend and Night of Museums draw more people. Prices often start to rise as summer approaches, but May is usually a better-value time than the busiest summer weeks.

Travelling with kids? Łazienki Park has room to wander, but save the Chopin monument area for a dry spell. For Night of Museums, check the event's route and venues before setting out; Warsaw's participating sites are spread across the city, and walking between them can take time.
