If the bubbles of coffee collect in the center of your cup, you can expect fair weather. If they adhere to the cup, forming a ring, you should expect rain. If they separate without assuming any fixed pattern, changeable weather should be on its way.I don't think I'd ever noticed bubbles in my coffee cup, but when I read about it I started looking for them. Sure enough, there they were! On inclement days the bubbles headed for the sides of the cup, but on the nice days they did stay in the middle
So, the coffee barometer worked. But why? I found the answer in a video on one of our local channel's Websites. The bubble's movement is caused by changes in humidity and air pressure.

Fascinating. I don't drink coffee every morning but I do keep track of the barometer as my head is easily affected by the pressure. I'll have to start looking at Terry's coffee as he does have a few cups every day.
ReplyDeleteI have a mini-barometer in my knee that's as least as accurate as the coffee bubbles :-)
DeleteThat is ver interesting. I have noticed bubbles in my coffee. Now I'll have to pay attention. You gave me another reason to be excited for my morning cup :-)
ReplyDeleteYou're welcome :-)
DeleteJust poured a cup of coffee on this Sunday morning. The bubbles are around the edge and our forecast is for 92 degrees today, sunny, no rain. So, I'm not too sure of this predictor. Maybe it has something to do with being at sea level, above, or below.
ReplyDeleteI think many "Farmer's Almanac" folklore-type predictions need to be taken with a grain of salt...but I also think they're interesting and fun.
DeleteIt's gloomy and 56° here; I WISH we were having your weather!
