That puts you in record territory. How would you describe your driving style? Full throttle all the time?
That's winter time driving. Granted, SF isn't as wintery as some places, but it's certainly plenty cold enough to drive up the Wh/mile usage.
I'd guess your 12 month average will be in the 340-350 range. Maybe lower as summer usage will drop substantially. Touring around Sonoma, I was getting pretty close to 300 Wh/mile when I visited last summer.
Interesting. Maybe reset one of the trip meters to see what usage is like now that the weather is warmer? Also, i do a fair amount of stop and go since we live in the city. I bet that contributes but the Avg still sounds high.
Also, how much variance do folks have between rated range miles and actual miles? Sometimes I feel there's a 30% discount in my case.

That's cool. Oh, I spotted the phone conversation to the right in your screenshot, that's all
The average January state temperature is from NOAA. It's a 30 year average, 1971-2000, so it's not terribly accurate for this last winter which as you note was very mild in the west and was very severe in the east. I don't know how NOAA defined the average - it probably includes night temperatures, and temperatures from colder places like the Sierras. I think we'd probably get slightly better predictions if we used last year's real numbers but I didn't see these anywhere on online when I did a cursory google search.

Elevation changes seems like a fairly recurrent theme in explaining higher wh/m. You, dlmorgan999, and mnx all note this in recent comments. The 8 kwh downhill (307wh/m) vs 14 kwh uphill (538wh/m) difference in your commute is pretty dramatic...
I often take the expressway to work and take the local streets coming back. Usually my wh/m numbers on the way back are a bit higher, but not dramatically so: I lose some efficiency from starting and stoping but gain some because I'm going slower. Are going up and down hills a lot?

Hills, rain, wind, top speed, temperature. All major factors. But his numbers are quite a bit higher than those of others in the same region.

If you don't think you're getting the range you should be, things you will want to check. For longtime owners these are probably known already, but they may help new owners:
* Alignment: As this thread mentioned, small adjustments in toe-in can make a significant difference in energy usage
* Tire pressure: Make sure your are within a few PSI of the rated pressure for your specific tires. If you don't mind a slightly rougher ride, go a few pounds over the rated pressure on the sticker in your door jam (not over the one on the tire, which is the max PSI)
* Do you have standard regen enabled, or have you turned it to low? For city driving this can make a big difference in energy usage
* Try to pre-condition your car's temperature before unplugging
* Enable Range mode, which will limit the power the climate control system uses, and will give you slightly better watts per mile. If you live in a moderate climate, you may not notice much of a difference

Ha! That's my daughter Christiana... Didn't show her # so I figured it was ok to leave in.

Also I have been wondering about alignment lately. After the rear tires were replaced (21") service did an alignment. Ever since then normal driving takes more effort. I had service try once again but it only helped a little.
400 miles per month, 12 miles a day. Lots of short trips, probably stop and go, all those hills in SF Bay area...if you run the AC hard, don't use range mode, goose it from time to time and you could see those sorts of numbers. Take it out for a nice 100+ mile road trip, keep it at or near the speed limit with the cruise on and see what you get...I suspect you'll see much better numbers.
Do you live on a hill and have a relatively short daily commute?

"more effort"
To keep the car straight? Something else?
