If general leisure events are more your thing (social events, sports) then we recommend checking out Meetings for New Expats in Łódź, Poland. You can also check out Łódź Yeddel (formerly Łódź Social), brought to you by the same people that provide the popular events organised by Warsaw Yeddel. The premise is simple - the majority of events are free, unless otherwise stated in the event info, so just turn up, mingle and have fun. Easy. Prior to the COVID-19 pandemic, Yeddel events were held frequently, but due to uncertainty about the ongoing situation none are currently taking place, but they will, thankfully, return in the near future. Check their site to receive updates on their eventual return and for a full list of all upcoming events.
If learning languages is more your thing, then Language Exchange in Łódź is right up your street. Here you can discover other people wishing to learn new languages. A free weekly meeting takes place in the city centre, and includes a mix of languages including English, Polish, and many other speakers of foreign tongues! The meetings are free, although out of courtesy, you are encouraged to at least buy one tea/coffee/drink in the premises. Visit the Facebook page to find out about any upcoming events and see general posts from members.
There are, of course, more general expat pages available on Facebook, such as Foreigners in Lodz, Foreigners in Łódź (note the spelling) and Lodz for Foreigners for general issues and topics, but it's not uncommon to see events advertised here too. If you're an Erasmus student in the city, then the official Erasmus Facebook pages for the University of Łódź and the University of Technology will be more than helpful.
Whether you're only staying in Łódź for the short-term, or you're in it for the long haul - we've got you covered!
