One tip I've seen is to go to the same place every week, for example a park, cafe, library, gym, etc. After a while you will start to see familiar faces and that can be a great way to connect with people. Joining local clubs and organizations is also good, like a fitness class, book club, volunteering, etc you might be able to find these on Facebook/social media. The bumble app has a bff mode for making friends too.
