The first opportunity to plant snap beans in Oregon can be estimated by looking at the USDA zone info.

Planting Calendar for Snap beans

Frost tolerance for snap beans:	Not tolerant of frost.
When to plant:	After the last frost has passed.

Since snap beans do not do well in cold weather it's necessary to wait until after the last frost has passed before you can plant them.

The earliest that you can plant snap beans in Oregon is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant snap beans and expect a good harvest is probably August. You probably don't want to wait any later than that or else your snap beans may not have a chance to fully mature. If you are starting your snap beans indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

On average the last frost when the weather gets warmer is on April 15 in Oregon. It might get as low as -5°F during the coldest months of winter.
