So it's getting cold up here in the PNW. Tonight's especially cold. I decided to make a decaf latte to relax with. Sure the beans were stale, but I figured I'd use them up before they got to be undrinkable. So I put them in my grinder, which never leaves 19.5g and I could swear it came out less than usual. I thought it might just be the beans, so I put some of my favorite Tanzanian Peaberry in because my roommate was wanting to pull an all-nighter. Same thing happened. It almost seemed like there was 10-15% less coffee than usual in the bin. I made sure the bin was empty and tared each time I ground, as I always do. Am I imagining things?

Yes humidity affects the beans, my moving up the fine scale 2 bumps every day has swung wildly since the rains started here just this last week. But check your weight on another scale to rule out an issue with your grinder.
Buying advice: GRINDER GRINDER GRINDER. Don't cheap out on the grinder.
