Hardwood floors are a staple in many homes looking for a luxury feel. They’re sleek, modern, and add a lovely accent to virtually every room. But not all hardwood floors are created equal and not all climates support hardwood flooring the same.

You may be surprised to find that the humidity levels can have profound effects on your hardwood floors in both good and bad ways.

As seasons change, your hardwood floors are going to change as a result. Dry seasons and more humid seasons both play a role in the way your hardwood floor feels, sits, and even the way it functions. Some of the changes are more dramatic than others but knowing what humidity and weather will do to your hardwood floors is key when you’re making your purchase.

Below are some of the ways weather, and specifically humidity levels, play a role in the feel and function of your hardwood floors

Cupping

This is a common problem during particularly humid times of the year. Cupping is when the edges of a hardwood panel rise over the center, creating a valley in the panel. This is caused by a disproportionate level of humidity distributed in the board. It’s not inherently damaging to the panel but can make your panels look a little bit misshapen at times.

Crowning

This is the exact opposite of cupping and happens for a different reason. In crowning, the center of the board will crest over the edges, creating a bit of a hill in the panel. This happens when treatment for cupping, usually sanding, is done too early in the process and the boards become disproportionate in response to weather and humidity.

Buckling

This is the most dramatic response to humidity your floorboards can have. Under extreme humidity, the floorboards may expand to the point where they pop out of their groves and the result is a large buckle along your floor. It will often go back down on its own, but it can leave space where the wood was stretched and may not fit quite right after.
