6b but studio is 7a 10 min down the road.
I’m at the foot of a valley and lots of woods / forest where I live

I was on the 7/8 line, now I’m a solid 8. Yay…

Clearly this is why it's important to understand ones own winters. They bumped me to a 6. When clearly last winter was one of the coldest in the books here.
Now we all understand microclimates...my lake front location is night and day different than 8 miles into town. Because of it. My spring night Temps never even level out until end of May.
Know your location...that map...is a good guideline to many. But clearly not everyone falls under their zoning intentions.

I'm located halfway in the middle of two outer lying towns. My weather app. Changes my location if I'm in one part of the house verses the other. Which I laugh about west/east wings.

HA HA! Baloney. Claims now we are 9a. Big joke! 8b temp wise still more accurate. "Average" annual low temp lower than 9a actually lower than 8b in truth. No way sub tropical here

Indeed. The USDA zones only give a good ball park estimate. They tend to lump western Washington into one or two micro-zones, but where I live in Kitsap County (a peninsula between two mountain ranges) tends to be a much more mild climate then some other parts of western Washington
Sunset Western Gardens takes my not-so micro climate into account. Inferring that we can grow some plants here that would not thrive on the "main land" of Washington.

I like how the new map is interactive and you can move and zoom it!

LOL. More alarmist fodder. This shows our last house is now 9a and our current house 1 mile away is 8b, with a minimum low of 15-20f. Never mind that it was 9-10f here for several nights in a row last December, leaving us (still) in 7b, and I recall 7f at the last house. Not running out to buy a tropical just yet.

We've been in NC three winters. The first two were 8B. The last (all time record-breaking cold) was 7B. Time will tell, but they just moved us from 7B to 8A, which (based on the last three winters) feels about right.HA HA! Baloney. Claims now we are 9a. Big joke! 8b temp wise still more accurate. "Average" annual low temp lower than 9a actually lower than 8b in truth. No way sub tropical here

Obviously some years will be higher or lower than your "zone" - especially with more extremes as of late - but the data is based on 30 year averages.

I’m in the same boat living next to the mountains it goes from 7-4 in a few dozen miles.

I moved from 6b to 7a but I live against the mountains so I noticed my temps are always 2-6 degrees colder then the temps the weather man calls out. So I might just stick with the 6a

Right...but clearly since winter 2013-14 I've seen significantly colder Temps. That winter is the winter that decimated my Ryusen. It's been harsh since. Clearly I'm a zone 4...no where by the skin of my teeth a zone 6 they have me listed now.Obviously some years will be higher or lower than your "zone" - especially with more extremes as of late - but the data is based on 30 year averages.

I still call hogwash. I could grasp them saying I was a 5. But to move me to a 6? No...no amount of honey will make me see that is calculated correctly.

yes these are just general guidelines…. I have 2 digital thermometers in my back yard and it’s always colder than forecast because forecast and temperature on weather station are always warmer but it’s not news..

Atlanta(ish) is now 8A listed at 10-15 degrees in winter. Last Christmas we had 3 days of 5degree cold. Gardenia, tea olive, loropetalum, pittosporum, rosemary, lavendar, chindo viburnum...all killed or frozen to the ground and these are yard planted landscape plants. Plenty of extremes, dont trust government charts other than to use as a vague outline
