Summer has to be my favorite season in terms of produce. Strawberries, cherries, tomatoes, corn... the list of delicious, ripe fruits and vegetables that can be attained locally at farmers' markets is virtually endless. Is corn in season right now? As summer peaks, you will start to notice the first ears of fresh, crisp corn appearing at local grocers and farm stands. Beyond enjoying corn on the cob, incorporating seasonal produce into your diet is a wonderful way to eat fresh—whether you are making vibrant summer meals or learning steps to build the perfect salad to pair with your grilled dishes.
| Corn Variety | Typical Peak Harvest | Best Culinary Use | | :--- | :--- | :--- | | Yellow Sweet Corn | June – September | Grilling & Roasting | | White Sweet Corn | June – September | Boiling & Fresh Salads | | Bi-Color Sweet Corn | July – August | Steaming & Corn Chowder |Corn is a type of grass that dates back over 5,000 years. The average ear of corn measures 12 to 14 inches in length and contains about 400 kernels arranged neatly in 16 rows. Most of the United States' corn crop originates from fields planted between March and July across major agricultural hubs like Iowa, Illinois, Nebraska, and Minnesota. Organizations like the Iowa Corn Growers Association highlight how central this crop is to American agriculture. When asking if corn is seasonal, remember that sweet corn reaches its peak flavor during mid-to-late summer. The most common type found in produce aisles is sweet corn, which comes in yellow, white, or bi-color varieties. It is a common misconception that kernel color indicates sweetness; kernel color has no effect on the sweetness of the corn, which is actually determined by the specific sweet corn variety and how recently it was harvested.

Key indicators when choosing peak-season sweet corn:
- Bright green, tightly wrapped husks
- Moist, golden silk (avoid brittle or brown silk)
- Plump, well-rounded kernels that yield a milky juice
When purchasing corn in season, look for ears that have fresh, tight, bright green husks. Stay away from those that are yellowed, dried, or showing signs of damage. If permitted at the market, peel back the husk slightly to check out the ears, which should be plump, bright, milky, and well rounded. The silk should not be brittle or brown, but soft and moist with a light golden color. According to produce selection guidelines from Iowa State University Extension, proper handling right after harvest is key to maintaining sweetness. Eat your corn as soon as possible to enjoy maximum flavor, as sweet corn tastes best right after harvest when its natural sugars are still retained. Until you are ready to consume, keep the ears in the fridge with the husks left intact to preserve moisture. Pair your sweet corn with other seasonal side dishes, such as delicious spaghetti squash recipes or fresh garden veggies, for a wholesome summer meal recommended by experts at the Academy of Nutrition and Dietetics.
