Does Fishing Line Deteriorate in Sunlight?

Fishing lines are made of a variety of materials, and each type is designed to withstand different elements. But one thing they all have in common is their vulnerability to sunlight damage.

Sun exposure can cause fishing line to become brittle and weak over time, leading to breakage and potential harm to fish and other wildlife. So, does fishing line deteriorate in sunlight? The answer is yes.

The most common type of fishing line is nylon monofilament. Nylon monofilament is a strong material that can withstand the wear and tear from use, but it’s also vulnerable to UV damage from the sun. Prolonged exposure to direct sunlight causes the plastic molecules in the line to break down, resulting in decrease in strength, flexibility and overall performance.

Other types of fishing lines, such as braided lines or fluorocarbon lines, may be more resistant to UV damage than nylon monofilament. However, even these materials are not completely immune from the effects of direct sunlight exposure. Over time, these lines will also become brittle and weak if left exposed to direct sunlight for extended periods.

The Solution
To avoid damaging your fishing line due to sun exposure, it’s important to take preventative measures such as storing your line in a cool and dry place away from direct sunlight when it’s not being used. Additionally, it’s important to check your line regularly for signs of wear and tear or brittleness that could indicate damage from sun exposure.

In conclusion, yes – fishing line does deteriorate in sunlight. To protect your gear from UV damage it’s important to take preventative measures such as storing your line away from direct sunlight when not being used, and check for signs of wear regularly.
