What is the best season for a spinner in your opinion? 

All of them, but I don't have to wait for ice out.

I think early spring is best.  

I've had luck with a spinnerbait all year long. It's the blade type that matters.

Fall seems the most logical. I really don't think it matters though. All of them.

They catch fish all year long, but I usually don't pick one up until the water hits about 50 degrees. In colder water I seem to do better on a rattletrap or jerkbait

Like most bass lures, spinners work year-round, but that wasn't your question.

In my experience, spinnerbaits work 'best' in early spring and again in late fall,

a winter sandwich you might say

Prespawn-Fall

Best times for me are prespawn, post spawn, summer and fall

All year! You can fish them at every depth and every speed to change it up for different situations.

Fall.

Some folks may disagree with me, but to be honest, I actually think they work the very best, far and above, during fishing season.

Sometimes they also work during the Hunting Season

By golly, I might have to try that. 

Lol, yelp, they work excellent during spring

Turkey season.. Windy, spring days on wind blown banks have always provided fish for me.

( spinnerbaits )

All year.

Yes.

They're at their best any time the water is wet.
