High humidity makes cloth mousepads slower.

Yes. Moisture in the air gets absorbed by the fabric fibers, making them swell and creating more friction. Your mouse feels like it’s dragging through mud.

This is especially noticeable with cheaper or untreated cloth pads. Some high-end pads have coatings or finishes that resist humidity a bit, but they still get impacted. A humid room can turn a fast, slick pad into a slow, sticky one overnight.

If you live somewhere humid, consider a hard mousepad (plastic, glass, or metal) for consistent glide. Or keep a dehumidifier running in your workspace. Your mouse won’t mind.
