When to visit & swimming

Best travel windows are late spring (May–June) and early autumn (September) for mild weather and fewer crowds. July–August are warmest but have more rain and thunderstorms. Warsaw is inland; there is no city sea temperature data — outdoor swimming in local lakes and river beaches is typically only comfortable in July and August when air temperatures peak.
