I've noticed it, but it isn't that major, thing is, it doesn't bother me much, anyway I prefer 45-30N latitude climates where even in June it goes dark at 9:00pm anyway, what bothers me more is the UV and sun strength now, which is already only a 6,
August is fine for me it's still summer and has a happy holiday feeling, but I can't stand that depressing summer is gone feeling between Mid-October and early/mid December.
