How important is precipitation to you?

Precipitation days matter much more than amount to me. Precipitation days would be a 4/5 but amount is more like a 2/5.

My dream climate gets 28”, but say 28” on 60 days is way too dry and 28” on 160 days is too wet. Precipitation days is more important, provided there’s a good amount of thunderstorms, anywhere from like 10” to 70” is fine with ~90-130 precipitation days.

4/5- important for me.
Ideally, a place would have between 750 to 2000 mm of precipitation annually, depending on the level of evapotranspiration (higher for tropics, lower for boreals).
I typically like moderate to high intensity (not extreme) precipitation events like thunderstorms and downpours; so around 40 to 110 precipitation days (depending on precipitation threshold) is ideal.
Lastly, a precipitation pattern is important, whether winter or summer dry season, as it influences agriculture. I preferably want an even distribution of rainfall year-round, with slight summer bias.

If this was human civilisation, precipitation's important would be an easy 5, obviously.

Temps are far more important as long as a climate isn’t overly wet (40”+ or 100+ precip days)

2/5 for precip totals, 3/5 for precip days. Not that important, though I do prefer heavy rain over fewer days to drizzly malarky spread out over more days. Some spring/summer precip is good for growing stuff without the need for irrigation.

For me, precipitation amount is the most important part of a climate, even more so than temperatures. You can dress for the temperature, but you can't stop rain from hitting your face unless you carry an umbrella.

I like semi-arid climates the best, too wet (humid climates) and too dry (hyper arid deserts) are both bad.

4. Rather important. Say, a very wet climate (2,000 mm+) with agreeable temps all year round will still be a C- for me, maybe D even.
