That unit, particularly closer to Montrose can still be pretty warm during the day. I would say expect 70-80 degrees at the lower elevations (closer to Montrose) during the day, and close to freezing at night. Some years frosts are rather late in that area of the state. However at higher elevations, where you'll most likely be hunting, I'd say expect 50-60 degrees during the day and below freezing at night, even down to 20 degrees or so. Snow is possible, but not likely.
So basically you need to prepare for a wide range of temperatures. Best advice is to dress in thin layers that you can remove as the day warms up. Rain is another possibility, so might want to consider bringing a waterproof jacket or raincoat.
Typically that time in October is a fantastic time to be outdoors in Colorado. Good luck! Let us know how you do.
Unit 62 is usually where a bunch of us hunt. We generally go first season but have gone 2nd combined.
I have experienced weather as low as the low teens at night and as high as the 80s during the day. More often than not, it has been a bit warmer than is ideal for hunting when we have been there. However, you must plan for any conditions. We have been there hunting in T shirts and get hit by a mid afternoon storm that dropped the temps into the upper 30s.
We will be there again this year 1st season with cow tags.
Let me start off by saying I am not a farmer.
I am a deer hunter and I do own a tractor and have all of the equipment - but that does not make you a farmer any more than standing in the garage makes you a car - well, you get the picture!
Having said that - and with most of my ineptitude fairly well hidden - I do think that buckwheat is one of the most under rated cover crops out there.
I say cover crop because I see mixed results as it relates to the deer eating the plants.
