Where to buy Hermiston watermelons
From Umatilla County farm stands to Portland and Seattle grocery aisles — how to find Eastern Oregon's sweetest melons each summer.
Grocery stores and regional retail
If you live in Oregon, Washington, or Idaho, check your local grocery produce section from mid-July through August. Chains across the Pacific Northwest routinely label bins "Grown in Hermiston" or "Hermiston watermelons" when Umatilla County harvest is in full swing.
Farm stands and farmers markets
Driving through Hermiston on Highway 395 or I-84? Seasonal farm stands and the Hermiston-area farmers market sell melons direct from local growers — often cantaloupe alongside watermelons. See our grower directory for listings as they are verified.
Wholesale and food service
Restaurants, casinos, and distributors source Hermiston melons through regional produce marketers. Volume buyers should read our buyer guide and plan procurement before peak season.
