Thermal question
I realize there are probably several variables here such as temperature and canopy density, but how long after sunrise does it typically take for the sun to create rising thermals on a valley floor? Thanks for the help.

Re: Thermal question
In my experience in Louisiana about 40 minutes. Next time you hunt in 30-45 degree weather pay attention and see if you get cold in feet and torso around the 7-8 o'clock hour. My theory is the thermals start rising and the cold air is pushed down to ground (or stand) level. If almost never fails, that you'll really notice it after somebody tells you about this phenomenon.

Re: Thermal question

As soon as the sun starts to peak over the horizon, when I get that first chill down my spine things will start happening. Though usually about mid morning I start to notice the upward movement occur. However, in the evenings I see the bottom drop out.

So usually 2 or 3 hours give or take before the rising thermals begin creating that wind tunnel along the ridge?

Id say thats about right on normal conditions. IDK if others would agree w this but usually after or about 10ish im really starting to not like what the milkweed is doing and feeling uncomfortable about my scent stream, sometimes sooner. Generally thats me setting up low for late buck and iv decided to call it a morning. I do not like moving around my sets midday so for the rut I prefer going for the 1/3 all day. I see it as the wind tunnel has its own "Prime Time" through out the day.

Re: Thermal question
Has anyone ever thought of the way the "steam" rises on a mountain side on a hot summer day then it rains and produces a "steam". I don't know what the word I'm looking for is. Mainly looks to be coming from around water sources, out of hollers, and sink holes or caves. I was just sitting here reading through old threads and that popped in my head. Could you possibly use those to find out how the thermals work in your area or maybe even where the thermals and wind meet?

Multiple guys have told me that steeper elevations increase the thermal pull. Especially a bluff. One of the best things you can do to be prepared is look at past and future wind directions. On variable wind days there will be gusts that your not sure why it happend.
