Poznań sää — huhtikuu

Wroclaw-forum threads on April weather describe a genuinely pleasant spring stretch by late in the month, temperatures commonly reaching the high teens with 8 to 9 hours of sun on a good day, though posters are consistent it's changeable enough to demand a proper jacket regardless of the forecast. Showers do roll through, but regulars call them short, typically an hour or two before clearing rather than settling in for the day. Wroclaw is repeatedly described as a touch warmer and less blustery than Gdansk on the coast, a real difference when planning a longer Polish itinerary across both. Posters call April a genuinely good value month for the market square and river walks, ahead of the summer crowds but past the harshest cold. The record: 15.8C days feeling like 12C, 3.8C nights, 47mm across 10.7 days, 1.4cm of late-season snowfall, 68 percent humidity and 9.5 hours of sun.

Forum posters describe January in Poland, Poznań included, as likely snowy and cold, though posters are direct this isn't guaranteed - one recent year turned out surprisingly mild, with temperatures well above 0C across much of the country. Posters generally describe the range of possible January days as genuinely wide: it could be +10C with heavy rain, -10C with heavy snowfall, sunny, or foggy, all within the same month. Posters consistently recommend checking a reliable Polish weather site closer to travel dates rather than relying on generic seasonal averages, given how variable a specific January in Poznań can turn out. Posters generally recommend preparing for cold, potentially snowy conditions while accepting that the exact experience varies significantly year to year.

Forum posters put July generally around 20-25C and pleasant, though occasional heat waves can push things warmer, and posters flag July as one of Poland's rainier months compared to May or September - with the caveat that many buildings lack air conditioning, so a heat wave can feel worse than the number suggests. For the visit itself, Poznan's Old Market Square with the town hall is called an absolute must, complete with a daily noon show of two mechanical goats butting heads on the tower - and the Old Town is described as lively and safe well into the evening. Visitors timing a trip for late June will just miss the Malta International Theatre Festival, though summer concerts pick up the slack in July.
