Does humidity affect bowstring performance?

May 8, 2026

Quick Answer

Yes, humidity affects bowstring performance, causing it to stretch, lose its draw weight and accuracy, and potentially lead to premature wear and tear.

Effects of Humidity on Bowstrings

Humidity plays a significant role in maintaining optimal bowstring performance. When the air is too humid, it can cause the bowstring to stretch, which leads to a loss of draw weight and accuracy. A 10% increase in humidity can extend the bowstring by up to 1/8 inch, affecting its performance.

Measuring and Maintaining Optimal Humidity

To maintain optimal bowstring performance, it’s essential to monitor humidity levels. Aim for a relative humidity (RH) between 30% and 50%. If you’re hunting in extreme climates, consider investing in a dehumidifier or using a bowstring sealant to protect the string from moisture. Regularly checking the humidity level can help prevent damage to the bowstring.

Techniques for Bowstring Maintenance in Humid Environments

To minimize the effects of humidity on bowstrings, adopt the following techniques: store your bow in a dry, climate-controlled environment; clean and inspect the bowstring regularly; apply a bowstring sealant to protect against moisture; and consider using a bowstring with a built-in moisture-management system. By following these techniques, you can ensure your bowstring performs optimally and lasts longer.
