Cool (but not cold ;) ). I’ve only been to Berlin in the summer, but from travel guides, it seems basically temperate and not overly-damp—there will be occasional snowfall, but no significant accumulation, and many days will have no cold rain to deal with.
Standard advice for clothing in variable conditions applies: look to layers, so you can adjust over time, and add/remove pieces when you go indoors or if the sun is out and it’s 5-10C warmer or cooler than you expected. A sweater/jumper over your shirt gives you flexibility here. I have a fleece undercoat with a waterproof shell that’s great in really cold conditions, and fine as just a shell when it’s warm (+5C) and rainy.
For meetups, you’ll still want to find covered areas—even if no rain is in the forecast, less moving air makes a noticeable difference in comfort. I suspect there’s no way to make it pleasant and effective enough to be worthwhile before you can do it in an enclosed (but not crowded) space, but I really look forward to hearing how it goes.
