Watermelon vs cantaloupe

Hermiston is watermelon country first — but cantaloupe shares the same irrigated Columbia Basin fields each summer.

Shoppers searching Hermiston melons usually mean watermelons — but several Umatilla County farms also grow cantaloupe (muskmelon) under the same hot-day, cool-night conditions. Both are vine crops that love sandy soil and controlled irrigation.

How to pick a ripe cantaloupe

  • Stem end should give slightly under pressure and smell sweet (not green/grassy)
  • Netting on the rind should be raised and golden-tan, not smooth green
  • Weight — heavy for size indicates juice content
  • Avoid soft bruises or mold around the stem scar

Why both grow here

Columbia Basin growers rotate and diversify irrigated acres. Watermelon drives regional brand recognition; cantaloupe and other melons fill farm-stand tables and short-haul wholesale when conditions align. Same climate advantages — heat for sugar, cool nights to hold it — apply to both crops.
