I doubt that the cool temps are going to harm the production on your beans. It didn't last all that long, if I understand. They will get going with warm temperatures. But while it's cool, they just sit there, biding their time.

I like to do another planting, even of pole beans, about a month later. Each planting comes in with a large "flush" of beans and then tends to taper off a bit. We like to can, so we like to have large quantities on had.

Bush beans tend to produce for about three weeks and drop off considerably in their production. But the variety makes quite a difference in this. There are some which really do quit. I grow one bush bean which simply doesn't quit, unless it gets hard hit by drought or insects, and hence, killed.

Most pole beans produce over a much longer period of time than do bush beans. I greatly prefer pole beans. Again, variety affects how tenacious they are. Some quit more easily than others, drying down to make dry seed. But, I have found that even those which are inclined to dry down and quit will continue to produce, over a long period of time, if they are kept well picked and well watered. They simply don't produce the same as in their "first flush."

Hope this helps!

In my particular part of the PNW, last summer we had nights that were at or near 40F every month of summer and beans did fine.
