It's a common summer concern: you head out to enjoy your garden or patio, only to find your favorite metal bench is too hot to touch. The short answer is yes, metal benches can become uncomfortably and even dangerously hot in direct summer sun. Metal is an excellent conductor of heat, absorbing solar energy rapidly. On a 90°F (32°C) day, a dark metal surface can easily exceed 140°F (60°C)—hot enough to cause burns in seconds.
However, not all metals are equal. Thick, cast aluminum or iron heats up slower than thin, sheet metal. Light-colored, powder-coated finishes reflect more heat than dark, raw finishes. The real key is material choice and placement. For consistently cooler seating, consider alternatives like wood, recycled plastic lumber, or concrete. These materials have lower thermal conductivity and remain much closer to ambient air temperature.
If you love your metal bench, simple strategies can help. Use breathable, outdoor-rated cushions or fabric covers to create a protective barrier. Positioning the bench in a shaded area, under a pergola or umbrella, is the most effective solution. You can also lightly mist the surface with water before sitting to provide temporary cooling through evaporation.
Ultimately, planning is everything. For high-sun locations, opt for non-metal materials. For decorative metal pieces, use them in shaded spots or employ accessories to manage the heat. With the right approach, you can ensure your outdoor seating remains inviting, not intimidating, all summer long.
