Yes, metal park benches can become dangerously hot in direct summer sunlight. On a sunny 90°F (32°C) day, the surface temperature of a dark metal bench can easily exceed 130°F (54°C) — hot enough to cause first-degree burns or discomfort within seconds. The science is simple: metal is an excellent conductor of heat. It absorbs solar radiation rapidly and retains that intense heat, unlike wood or certain modern composites.
This isn't just about minor discomfort. For children, the elderly, or pets, contact with a superheated surface can pose a real safety hazard. A quick touch test with the back of your hand is a wise precaution before sitting down.
So, what can you do? Seek benches under the shade of trees, which can be 20-30 degrees cooler. Many parks now install benches made from alternative materials like thermally resistant wood, recycled plastic lumber, or coated metals designed to reflect more heat. If you must use a sun-exposed metal bench, having a simple barrier like a towel, blanket, or even a spare piece of cardboard can make it safe and usable.
Ultimately, while metal benches are durable and low-maintenance, their heat retention is a significant summer drawback. Being aware and planning ahead ensures your park visit remains pleasant, not painful.
