What is the best time to visit Poznań for good weather?
Late spring (May to June) and early autumn (September to October) offer the most comfortable conditions for exploring the city, with mild temperatures and fewer crowds. July and August are the warmest months, with average highs around 24°C, but they also bring the highest rainfall and summer holiday crowds. For value, consider late April or early October, when accommodation prices are lower and the weather is still pleasant.
What should I pack for a trip to Poznań?
Pack layers year-round. In summer, light clothing and a rain jacket are essential; evenings can be cool. For winter (December to February), bring a warm coat, hat, gloves and sturdy waterproof shoes—temperatures often drop below freezing. Spring and autumn require a mix of long sleeves, a mid-layer and a waterproof outer shell. If visiting in December, be prepared for snow and icy pavements.
