I'm not sure of the weather but I'm guessing cool since mid summer was around 55/65 degrees. I do know that is their rainy season but as to how cold or how much rain I couldnt tell you. As far as the cost, there are tons of places that you just pull up and park on the side of the road or in small parking lots for free. I recommend the Prairie Creek area as that is where the "Titans" are (some of the world record holders). There are many trails in this area and it's all free. The Rockefeller Loop is also pretty cool as it has some of the largest and oldest trees. What was once the tallest tree fell down here and it is pretty cool to walk the distance and see actually how tall the tree once was. There are alot of downed trees in the Rockefeller loop because of the age of some of the trees and you can get a lot of awesome pictures in front of the roots. Both are awesome places to see and were my favorite and both were free and very easy to find parking.
February is gonna be cold, the redwood park is free.
I WOULD LIKE TO VISIT THERE IN WINTER..
