I have a few, they tend to change around.
First and foremost is rugby. 2 practices a week starting in April, games on Saturdays late-May to mid-August, indoor touch November-March. Currently just a player with some minor involvement in running my club, but eventually I plan to transition to refereeing.
Not sure I'd call sports fandom a hobby but I'm a season ticket holder for the Toronto Arrows (rugby) and Hamilton Tiger-Cats. Do my absolute best to make every game for both.
My newest hobby is my project truck. Actually I have two now, a major restoration on a 1993 GMC Sierra, and this spring I picked up a 2002 Sierra to have a second driver / be on deck if I even finish the 93. So far I've just tackled a bit of paint/rust repair.
My main "indoor" hobby is homebrewing. I don't really do experimentation or curiosity anymore, I have basically dialed in 4 regular recipes that covers what I like to drink. I also dabble occasionally in making whisky, although it's dropped off since I don't drink whisky nearly as much as beer.
Have been doing quite a bit of smoking, curing, and BBQ. My Christmas gift this year for family/friends is going to be a freezer box of assorted meats, probably some combination of peameal bacon, belly bacon, Montreal smoked meat, or sliced Texas-style brisket. I have beef jerky kit I haven't gotten around to trying out, and I want to add sausage-making to my repertoire.
I used to be very into woodworking in general, and found my niche in making electric guitars. This was in high school and early college. I basically had to stop because I wasn't confident enough in my work / motivated enough to sell them, and I couldn't just keep making more. I also realized I liked building them a bit more than playing them... so both hobbies dropped off. I still have all my guitars, including the half-built ones that have been sitting for a decade. I only pick one up to strum very occasionally, although I did recently drag my amp out of storage to attempt to get back into it.
Next up on my radar is cheesemaking. I've watched a bunch of videos on the basics, and am about ready to start, just need to address my disaster of a basement brewery to make room.
