When choosing outdoor seating for areas with frequent rain, durability and weather resistance are key. The best materials include:

1. Teak Wood: Naturally resistant to moisture and rot, teak is a premium choice for outdoor furniture. Its high oil content repels water, making it ideal for rainy climates.

2. Aluminum: Lightweight yet sturdy, aluminum is rust-proof and can withstand constant exposure to rain. Powder-coated finishes add extra protection.

3. Polyethylene (PE) Rattan: Synthetic rattan is waterproof and UV-resistant, perfect for wet conditions. It mimics natural wicker but lasts much longer.

4. Stainless Steel: Highly resistant to rust and corrosion, stainless steel is a durable option for rainy areas, especially when paired with weatherproof cushions.

5. Marine-Grade Polymer: Designed for harsh environments, this material is fade-resistant, waterproof, and requires minimal maintenance.

For longevity, opt for furniture with waterproof covers or storage solutions during heavy rainfall. These materials ensure your outdoor seating remains stylish and functional, even in wet climates.
