Question
I am building two outdoor benches to sit in front of a restaurant. What is a good wood choice? It will be out in the rain and direct sun. The finish will be a thin paint with a lot of the raw wood showing through, kind of antiqued. I have learned my lesson with wear and tear in a public situation so cedar, redwood, cypress, and fir are not durable enough.
The obvious choice is teak but it is very expensive. Ipe will work but what about African mahogany, oak, maple, alder, ash, and poplar? Is there a study out there about best woods to hold up outdoors? Rot is probably not an issue as it will sit on a cement patio but expansion and contraction in the rain and hot sun is more of an issue.

From contributor L:
White oak is an excellent choice as an exterior wood - not red oak.
Otherwise if you are going to stain it (or use a semi-transparent stain/paint) I would go with redwood because I've found it's sometimes denser than the other easily accessible softwoods. It also is naturally weather resistant.
