What’s In Season in Colorado This October?

Written by Wellness Connections | October 01, 2025

October in Colorado brings the heart of fall, with cooler days, crisp air, and hearty, flavorful harvests. This month, pumpkins, leeks, onions, and cantaloupe shine at farmers’ markets, offering both nutrition and seasonal charm. Eating seasonally means enjoying the freshest produce while supporting local growers.

Pumpkins

Pumpkins are a fall staple, rich in fiber, vitamin A, and potassium. They support eye, immune, and heart health. Roast them for a sweet, caramelized side, puree for soups, or use in baked goods for a comforting seasonal treat.

Leeks

Leeks are tender and mild, adding subtle onion flavor to soups, stews, and sautés. Packed with vitamins A, C, and K, they support immune function, bone health, and digestion. Their versatility makes them perfect for cozy fall meals.

Onions

Onions are in peak season, offering flavor and nutrients like vitamin C, antioxidants, and sulfur compounds that support heart health and immune health. Use them raw in salads, caramelize for sandwiches or sides, or add to hearty soups and roasts.

Cantaloupe

While less traditional for fall, late-season cantaloupe can still be found in October. Bursting with vitamin C, potassium, and hydrating water content, cantaloupe makes a refreshing snack or addition to salads and smoothies, providing a sweet contrast to autumn’s savory flavors.
