I too rely on the hourly weather forecast. Also, on my way out, I glance at a place that's got a American flag lit up at night. It works as good confirmation.
Some suggest taping a thread to your gun barrel--. It'll blow with the wind, although I imagine it can become hard to see.
Someone mentioned thermals, and to add a bit, your scent tends to go down in the evenings as the temperature drops.
At some point, wind will you surprise you. Two things that help me over the years have been having more than one spot to hunt, different approaches to the stand, and also being willing to stillhunt if a stand placement won't work and I can get positioned to properly work the wind. . .
