Understanding Equilibrium Moisture Content (EMC) is vital for the beauty, stability, and long-term performance of architectural millwork, doors, and exterior wood products. At 1st Choice Millworks, we’re pleased to share this comprehensive USDA Forest Products Laboratory report titled Equilibrium Moisture Content of Wood in Outdoor Locations in the United States and Worldwide. It provides detailed average monthly EMC values for 262 U.S. locations (including many in Oklahoma and across the Midwest) and 122 international cities. Whether you’re specifying kiln-dried lumber, planning storage, or designing for a specific climate, this resource helps ensure your wood products are properly matched to local conditions—minimizing movement, checking, and warping over time.
