Clay courts are a type of tennis surface made from crushed brick, stone, or other materials. They are known for their distinctive red or green color and provide a slower playing experience compared to grass or hard courts. The surface allows for a higher bounce of the ball, which can affect the style of play and strategy used by players. These courts are commonly used in professional tournaments, including the famous French Open. Players often find that clay courts require more stamina and patience, as rallies tend to be longer. Additionally, the surface can be affected by weather conditions, making maintenance an important aspect of clay court management.
