Hi @langerking I find that in the winter my tuning tends to run flat, and the hot humid summers if anything, I run a little sharp. Keep in mind that indoor heating makes the relative humidity drop like a stone, so definately my humidity runs really low indoors in the winter (10-20%), which is why I try to pay attention to keeping my guitars in their cases with humidipacks during the winter months.
