The last month that you can plant pea and expect a good harvest is probably August. You probably don't want to wait any later than that or else your pea may not have a chance to fully mature. You can get started a few weeks earlier by starting your pea indoors.

Last Frost Date

On average the last frost is on May 15 in Zone 4a. It might get as low as -30°F during the coldest months of winter.

Since the USDA zone info for Zone 4a is not always accurate our actual date of last frost is different every year. Since half of the time in Zone 4a there is a last frost after May 15 be ready to cover your pea if we have a late frost.
