I personally use metric as much as I can. The temperature on my phone for example is in celsius, try me.

Because for weather, °F is arguably better. 0°F - 100°F is the general range that most weather on the planet happens at (yes I know there are extremes where it gets to like -30°F or 120°F, but bear* with me). You can then further break those up into 10°F segments that are a bit more practical and granular than 10°C segments:

• under 0°F: stay inside
• 0°F - 10°F: really fucking cold, don't stay out too long or you risk hypothermia
• 10°F - 20°F: still really cold, but you can stay out long enough to shovel your driveway without fear of losing fingers/toes, if you're wearing winter gear
• 20°F - 30°F: cold but not bitterly so. Perfect weather for outdoor winter activities like sledding or snowball fights
• 30°F - 40°F: Snow starts melting here, and you can probably ditch the scarf, but you still need a winter jacket
• 40°F - 50°F: Too warm for your heavy winter jacket, to cold for your light spring jacket. It's layering season baybee
• 50°F - 60°F: still layering season, but you can probably get by with just a light jacket at this point, especially if you're doing something active outside. Some people start breaking out the shorts, but that's not the norm.
• 60°F - 70°F: a more generally acceptable range to start wearing shorts and short sleeves. Perfect temps for doing yard work and sipping beers on the patio alike
• 70°F - 80°F: definitely shorts weather, and pools start coming into play. If you're doing something rigorous outside, you're probably sweating
• 80°F - 90°F: you'd probably rather be inside, if you're not in a pool. You'll be sweating just lounging in your deck chair.
• 90°F - 100°F: hot as balls, probably not worth going outside for very long, as the pool water feels like taking a dip in lukewarm soup
• Over 100°F: stay inside

Now I know you can do something similar with °C, but the workable range there is smaller, because you're going from like -15°C to 40°C. It's less granular, and the start/stop temps are more awkward.

Is it weird that water freezes at 32°F and boils at 212°F? Sure, absolutely. When you're doing stuff in that context, it absolutely makes sense to use Celsius, where you're working on a nice, neat 0°C-100°C range. But weather, the thing most people contextualize temperatures with, doesn't happen in that range. It starts well below freezing, and (hopefully) doesn't get anywhere close to the boiling point of water. For that, I'd argue °F is actually a little more useful.

Because it doesn't have as much resolution as Fahrenheit.

There are 180 degrees between freezing water and boiling water in °F. But 100 degrees between the two in °C. So with Fahrenheit we can give mote accurate temperature info without resorting to decimal degrees. And if your response is "learn to handle decimals" then the same argument can be given for inches vs mm.
