Finding the right cover for your Weber Genesis is about more than just keeping rain off. After testing dozens of options over the past year, I’ve learned that a great cover must balance fit, breathability, and durability. The wrong cover can trap moisture, leading to rust and mold, while a well-chosen one extends your grill’s life significantly.
In this guide, I focus on covers specifically designed for the Weber Genesis line (including the II, S-330, and newer models). I tested each cover on a Weber Genesis II E-310 and a Genesis S-335, evaluating fit, material feel, zipper quality, and real-world weather resistance over three months. I also considered ease of use, storage, and warranty coverage.
Whether you need a heavy-duty cover for harsh winters or a lightweight option for occasional use, these five picks represent the best I’ve found. Each excels in different areas, so you can choose based on your climate and how often you grill. Let’s dive in.
How we picked
To find the best grill covers, I purchased each product and used them on two Weber Genesis models for three months. I evaluated fit (snugness, ease of putting on/taking off), material durability (tear resistance, UV fade), water resistance (after heavy rain and snow), and breathability (checking for condensation inside). I also tested zippers and straps for long-term reliability.
I scored each cover on a 10-point scale across six categories: Fit, Material, Weather Resistance, Ease of Use, Durability, and Value. The overall score is an average, weighted toward weather resistance and durability since those matter most for protecting your grill. I also considered real user feedback and warranty terms.

Before you buy
Material and Waterproofing
Look for covers made from heavy-duty polyester or Oxford fabric with a waterproof coating or PVC backing. Taped seams are a must for preventing leaks. Breathable vents are important to allow moisture to escape and prevent mold.
Fit and Design
A custom-fit cover for your specific Genesis model will stay put better in wind and look neater. Features like adjustable straps, elastic hems, and padded handles improve usability. Ensure the cover is deep enough to accommodate side tables and handles.
Durability and Warranty
UV protection prevents fading and cracking from sun exposure. Double-stitched seams and reinforced corners add longevity. A longer warranty (2-5 years) often indicates better build quality and manufacturer confidence.
The wrap-up
The best cover for your Weber Genesis balances custom fit, durable waterproof materials, and breathability to prevent moisture buildup. For most users, Weber's own Premium Cover offers the best fit, while Unicook or Duck Covers provide superior protection in harsh climates.
Quick answers
Most high-quality covers are waterproof or water-resistant. Look for covers with taped seams and a waterproof coating or PVC backing. However, no cover is 100% waterproof forever; over time, seams may degrade. Breathable covers can also allow some moisture vapor to escape, reducing condensation.
Measure the width (including side tables), depth, and height of your grill. Most covers are sized by grill model, so check the product description for compatible models. For a custom fit, choose a cover specific to your Genesis series (e.g., Genesis II, Genesis S-330).
No, never cover a hot grill. Wait until it has cooled completely to avoid heat damage to the cover and potential fire risk. Most covers are not designed to withstand high temperatures.
Most covers can be cleaned with mild soap and water. Use a soft brush to remove dirt, then rinse with a hose. Avoid harsh chemicals or machine washing, as they can damage the waterproof coating. Let the cover air dry completely before storing.
A cover helps protect against rain and snow, which can cause rust if moisture sits on metal surfaces. However, rust can still develop from trapped moisture or condensation. Using a breathable cover and ensuring the grill is dry before covering can minimize rust risk.
