Météo à Sopot en septembre

Regulars are consistent that this coastal city's weather stays changeable this month specifically because of gusts coming off the sea, chilly enough in the mornings and evenings that a sweater or light jacket is standard advice even when the afternoon itself turns pleasant. Our row backs the mild-but-breezy read, 19.8C over 10.4C nights, with 49.5mm of rain across 8.5 days and a real 20 kph wind. Multiple regulars who've returned across several Septembers describe the month as reliably fine overall despite the day-to-day variability, making it a solid choice for both Gdansk and nearby Sopot. The sea holds 19.8C. The record: humidity 76 percent, 8.8 hours of sun and AQI 43.

There isn't a dedicated Sopot thread for February, but the Tri-City forum covering Gdansk and the surrounding Baltic coast is clear that this is a genuinely cold, quiet month - temperatures can drop well below freezing, plenty of locals head off somewhere warmer, and the seaside promenade that's packed in summer is nearly empty. Museums and some attractions may run reduced hours, but pubs and cafes stay open and cozy. It's a legitimate off-season visit if you want the pier and beach to yourself, just dress for real winter, not a mild coastal chill.

Forum posters describe August as one of the warmer, drier months, typically around 24C, with the heaviest summer rain more associated with July - meaning the back half of August tends to be a safer weather bet than earlier in the month. Posters are candid that Sopot gets genuinely crowded in July-August, its peak beach season, so anyone wanting a quieter visit is directed toward the shoulder months instead. One practical swimming-related caveat: the same warm, calm, low-rain conditions that make August pleasant can also trigger algae blooms in the Baltic, occasionally leading to beach closures - a real but year-varying risk rather than a given.
