Can't climb for a couple months, any similar hobbies I could try out?

Looking for a new outdoor hobby or two to replace climbing for a few months. Some things I love about climbing that I would like to have in my new hobby, but doesn't need to have all of them: 

• Can be done solo or with people
• Friendly/welcoming community 
• Problem-solving/technical (e.g. having to work through a project) 
• Provides a sense of progression and accomplishment (e.g projecting higher climbing grades, sending projects) 

I don't know, that could be basically anything. Maybe try getting a job, hippie.

Make a quilt for your grandmum.

Its crucial to be flexible. I don't gym climb but when it rains I play guitar, go canoeing or read a book. Winter time I ice climb but when the ice sucks usually the skiing is good and when the skiing sucks usually the ice is good and I can still play guitar and read a book. Toying with the idea of learning a new language.   

Wingsuit flying

Climbing and golf are almost identical. If you climbed trad, don’t ride the cart. 

I like sewing. Also, 'batin.

I'll take a stab at a serious answer. Mt. Biking.

Sex.

Fly fishing checks all the boxes.

I got a shoulder injury about 3 years ago...and once I could tell it was going to take a while to heal, first I tried running but my knees went, "nope!" So I took up painting (outdoors whenever possible!) and I've been so totally surprised at how many parallels there are with climbing. The biggest similarity is that when I make a painting that I don't totally hate, I get that exact same kind of happy feeling as sending a project, whatever that neurochemical reward in the brain...

Painting hits all your bullet points. I've felt like there is an incredibly warm and welcoming community in artists...I've made new friends through it. Before covid times I met awesome people through art classes and workshops and right now there are many great zoom art classes to get started. You can go outside and paint, get in a beautiful hike, solo or with people. The sense of progression is very tangible as you learn new techniques, but just like climbing there will be "on" days and "off" days. The problem-solving/technical side of your brain gets a HUGE workout! It is fun to think through how to get from blank paper to the painting that you want.

I didn't think art was going to check so many of the same boxes as climbing so it came as a total surprise that it did!

Are you injured or just looking for something different? may help to know

Woodworking or some type of making

flip cup

I think slacklining would be a great fit. 

What kind of injury? Hiking and especially scrambling seem to scratch the itch for me

Hot spring hunting is a blast. usgs post all known geothermal or many other similar sites.   Big plus is locating those hidden gems.   Mix that with rafting for a Win/win.  

Skateboarding is an option. It is all about failing 90% of the time, just like climbing at your limit!

Trail running can be very rewarding and a great way to scope out potential climbing areas for the future

I recommend skydiving if your second criterium isn’t that important.

Skiing/snowboarding

Surfing

Mountain biking
