    I learned the hard way a long time ago that sleeping bag ratings are the temperature that you will be utterly miserable. Your bag is not the place to try to cut weight or save money IMO.

    No stats, just experience rolling with EEs for a decade. A 40deg EE quilt starting May 15th, perfect.

    I bet you will regret the 40f setup a few nites. June, July, August from VA to VT...I'd go for it. Get your winter gear in Glencliff.

    I've learned my two pound, 35f bag is neither of those things after one week.

    Okay, I’ll lever off this thread. Sectioning Springer to Fontana in July. 40F should be plenty, right

    Based on comments above and weather data I think a 40F bag/quilt would be fine but generally warm so camp high. If you own a 50F bag, take it plus maybe an extra morning layer?? The average low temperature for July 1 is 11F warmer than May 15 , is 13F to 21F warmer than Oct and holds steady throughout July.
    Anybody with July experience on the AT in the south?

    Now for too much information.
    Data from Weatherspark.com for Gatlinburg Airport (~1000', ne of Fontana, just north of SMNP)

    "July high temperatures are around 83F rarely falling below 77F or exceeding 90F. Daily low temperatures are around 65F, rarely falling below 58F or exceeding 69F. " (note: these temps in today's warmer world may be 2F higher)
    The absolute lows for all of July at Gatlinburg for the last five years starting in 2019 are 57, 65, 59, 67 and 62 (=62 ave).

    Shelter altitudes (whiteblaze) vary from 4900' to 2300'. Subtracting 12F and 4F suggests at 4900' the coldest night for all of July for the last five years would have been 45, 52, 47, 55 and 60 = 50F average but at 2300' only a 58F average. Using adjusted(+2F) monthly averages suggests the average low at 4900' might be 55F and at 2300' might be 63F.

    And more gobbledygook.

    Postholer.com suggests that the average low of the coldest spots for section 1 and 2 (split at Hiawassee) are 58F and 55F.

    For average temperature changes with altitude, I now use -3.1F/1000' calculated from average temperatures on top of Mount Mitchell compared to Asheville.
    https://www.climate.gov/news-feature...d-lows-climate).
    This is ground level data as opposed to the -3.5F/1000' which is atmospheric data. At some point, I guess I can compare more data from shelter weather predictors at different altitudes in more varied weather. The shelter predictors don't have historic predictions.

    With pleasure. Let us know when you get back how many nights you were out, and the particulars of your coldest night(s). (clothing, sleeping set up, location, Temp??, and how hot/cold you were)
