Maintaining your court surface is essential for optimal performance, safety, and longevity. Weather conditions, including extreme heat, heavy rain, freezing temperatures, and blowing wind, can affect a court’s surface over time. It’s important to understand how different weather situations can impact a sports court surface and what protective measures you can implement to help extend its lifespan.
Effects of Weather on Different Court Surfaces
Heat and Sun Exposure
Asphalt and concrete courts: Prolonged exposure to UV rays can cause the surface to fade, discolor, and develop cracks. Heat and sun exposure can also soften the coating of the court.
Clay courts: Excessive heat dries out the clay, making it loose and affecting ball bounce.
Synthetic and acrylic courts: Extreme heat can soften synthetic materials, leading to cracks, deformation, fading, and warping on the court’s surface.
How to Protect Your Court
Apply UV-resistant coatings or sealants to prevent color fading and maintain the integrity of the court. Use acrylic mixes and expansion joints so the court can contract and expand without causing damage. You can also provide shade structures or install windbreaks to reduce direct sun exposure. For clay court, make sure to water it regularly to maintain proper moisture levels and reduce the chance of cracks or other issues.
You should regularly reseal and resurface your court to extend its lifespan and prevent heat and sun damage.
Rain and Moisture
Hard Courts: Standing water can lead to cracks, surface deterioration, mold/mildew buildup, and dangerous slick spots that could lead to injuries.
Clay Courts: A clay court performs best when damp, but excessive rain can wash away top layers, turning it into a muddy mess and requiring you to pay for more frequent resurfacing.
Grass Courts: Overwatering or heavy rain leads to uneven, muddy, and slippery surfaces that can cause slips, falls, and poor performance. Grass courts will also take longer to dry when soaked.
How to Protect Your Court
Install proper drainage systems so you can prevent water pooling and quickly remove water from the playing surface. Make sure you also have a very slight slope (1%) in one direction to help water run off the court.
For additional protection for a hard court, use a waterproof sealant and cover it with a tarp during heavy rain.
Cold and Freezing Temperatures

Asphalt and concrete courts: Temperatures cause asphalt and concrete to contract, leading to internal stress that creates cracks. If water seeps into these cracks and temperatures drop again, it will freeze and expand, causing more issues. Repeated cycles of freezing and thawing significantly deteriorate the surface. Freezing water can also cause the ground beneath the pavement to swell, leading to uneven surfaces and even more cracking.
Clay courts: Freezing temperatures turn the water in the clay into ice, which expands and causes the court to become uneven and hard, making it difficult to maintain playability. When the ice thaws, it can pool and lead to a muddy and unplayable court.
Synthetic courts: Cold may make synthetic materials brittle and more prone to cracking, but, overall, synthetic courts hold up the best to freezing temperatures.
How to Protect Your Court
Clear leaves, dirt, and other debris before winter to prevent mold, mildew, and surface staining. Make sure to also repair cracks and surface damage to prevent further issues from freeze-thaw cycles. During the winter, make sure to remove snow with a plastic shovel. Store clay court maintenance materials in temperature-controlled areas. Additionally, consider using frost-resistant coatings or covering the court, especially if made of clay, with a protective tarp.
Wind and Debris
Strong winds can blow dust, leaves, and debris onto the court, which can wear down and compromise the texture of the court surface. Wind can also affect traction and ball movement.
How to Protect Your Court
You should frequently clean the surface to minimize the accumulation of debris and preserve the court’s functionality. You can also add windbreaks, such as fencing or hedges to reduce the impact of strong wind gusts, and use court covers if the court isn’t being used.

Protect Your Court No Matter the Weather
No matter the weather, make sure to sweep and remove debris frequently; ensure proper drainage so water flows away from the court surface; perform regular checks for cracks and fading; and reapply coatings and resurface courts when needed.
By taking these preventive measures, you can ensure that your court remains in great condition, regardless of the weather conditions. Proper maintenance will enhance playability, safety, and longevity for many years.
