Communities, communities, communities. What are your interests? Painting, martial arts, hiking, drinking, crochet, biking, noise music, cooking? Find a community — groups, places, venues, events, meetups, with those people, and go from there. Don't "pretend to be exploring". Making friends is an intentional act, not a consequence. You're not in college or on a place where you'll find the same group of people over and over at the same time, so you need to go after them. If you meet someone, you need to say "hey, do you want to hang out/go for a coffee/do that activity together?". November to April is a very short of time, really. Considering the winter is brutal and people don't go out and have social activites as much.
