Its pretty simple really. Ask a leafer from Washington state what temp bars they get to on a hot summer day with lots of L2 charging. Anything more than that gets you the degradation we see in the south.
Nissan has never owned up to the how hot is too hot issue. I don't know why you would expect them to do it now.
Sure, but even WA state has a huge variance in temperatures. And, there's a huge variance in temps in in the SF Bay Area and So Cal. Some parts of CA are milder than some parts of WA.
And, there's the huge ranges of each bar and their overlap. If http://www.electricvehiclewiki.com/Battery#Battery_Temperature_Gauge is accurate, 6 bars could range from 50 F to 100 F, while 7 could range from 73 F to 117 F. It seems like it's basically a black box as to how many temp bars are visible vs. the actual pack temp.
Take a look at these average high temps by month in the graphs in the middle of each page:
Seattle, WA: https://weather.com/weather/monthly/l/USWA0395:1:US
Spokane, WA (Eastern WA): https://weather.com/weather/monthly/l/USWA0422
These two are pretty hot parts of WA (found them via http://nwpr.org/post/hottest-place-washington-state):
Pasco, WA: https://weather.com/weather/monthly/l/USWA0338
Kennewick, WA: https://weather.com/weather/monthly/l/USWA0205
Concord, CA: https://weather.com/weather/monthly/l/USCA0247:1:US - this city is known to get pretty hot in summers
San Jose, CA: https://weather.com/weather/monthly/l/USCA0993:1:US
95120 zip of San Jose, CA: https://weather.com/weather/monthly/l/95120:4:US - this part is usually noticeably hotter than the usual reported temps for San Jose (usually the news reports downtown for SJ)
San Francisco, CA: https://weather.com/weather/monthly/l/USCA0987 - this is definitely quite far south from WA state, yet SF is consistently very mild compared to some other much hotter parts of the Bay Area, likely due to its ocean proximity
Pacifica, CA: https://weather.com/weather/monthly/l/94044:4:US - also has a mild climate since the Pacific Ocean is one of its borders
Santa Monica, CA: https://weather.com/weather/monthly/l/USCA1024:1:US - in So Cal. Doesn't get very hot, likely again due to its proximity to the ocean
Re: SF vs. hotter parts, in the summer, it's not unusual for some parts to hit 90 F to 100+ F, while city of SF might be in the 60s or 70s.
I just take issue w/recommendations that seemed to recently pop up from thin air, possibly from Leftie, partly because of the lack of official statements/documentation from Nissan + the above huge ranges, overlap + black box.
