We don't get out to hunt much with everything else going on in our life, but today my son and I got the chance to squirrel hunt and dove and quail and rabbit. It's a great time of year.
The wind was whipping at a steady 7 - 12 mph with gusts up to 15.
Is this too windy for squirrels?

If its windy,most of the time u'll see more on the ground.Ive had best luck on calm sunny mornings.A light breeze dont matter much,they just dont move as much on windy days.

Those winds aren't too bad. I'd say if winds are sustained over 15 then there wouldn't be much activity. I see some on windy days but only a few.
