How Long Does Cedar Take to Air Dry?

Smell the fresh cedar in your backyard. For wood fans like you, cedar is more than wood – it’s your creative canvas. Before it’s your deck or gazebo, cedar air-dries. This journey from tree to masterpiece is key for your cedar projects.

So, how long does cedar take to air dry? Getting cedar to dry isn’t as simple as we might want. It depends on a few things, like how thick the wood is, the weather where you live, and the place you’re drying it. 


Generally, cedar can take anywhere from several months to a year to air dry properly. The goal is to reach an ideal moisture content that allows the wood to be worked with effectively without compromising its structural integrity or aesthetic appeal.

The time it takes for cedar to air dry depends on the type of cedar and the climate:

  • Kiln-dried clear cedar: Takes 14–17 days.
  • Dry knotty cedar: Takes 7–10 days.
  • Green (unseasoned) cedar: Takes at least 30 days.
  • One-inch stuff: Can be ready in about two weeks in warm weather but four to six weeks in cooler weather and more humid climates
  • Incense cedar: Can take several to as much as 18 months to air dry

Understanding the Drying Process

Let’s explore the difference between air-dried and kiln-dried wood. Does cedar need to be kiln-dried? Not necessarily. While kiln drying is faster and allows for more controlled conditions, air drying cedar is a time-honored method that many purists prefer. 

It’s a natural process that can enhance the wood’s color and grain, making it a favorite among traditionalists.

Kiln-Dried vs. Air-Dried Western Red Cedar

Kiln drying is a process where wood is put into a big oven, and the temperature and humidity are controlled carefully to take out the moisture. This process can be completed in a matter of days or weeks. 

On the other hand, air drying uses the natural flow of air and usually takes a longer time. The slower pace of air drying allows the wood to acclimate to the ambient humidity, reducing the risk of warping or cracking.

Moisture Content for Clear vs. Knotty Material

The moisture content of cedar is a critical factor in determining its readiness for use. For clear, knot-free cedar, the desired moisture content is typically around 6-8% for indoor use and 12-15% for outdoor applications. 

Knotty cedar, which is often used for its rustic appearance, may have slightly different requirements due to its varied density and grain patterns.

Tips for Air Drying Cedar

Here are some tips for air-drying cedar:

  • Seal the ends with wax.
  • Place it somewhere outside under cover, out of the direct sun
  • Use stickers (thin strips of wood) under it to allow air circulation
  • Wait approximately one year for each inch of thickness to minimize cracking
  • Place 3⁄4″ to 1″ square wooden spacers, each 4 feet long, between layers of boards to let air circulate.
  • Use 2-inch wide ratchet straps to secure boards in the cut order when stacking them.
  • Use a moisture meter as the real test.
  • If the wood consistently feels colder than the room and the weight is decreasing, it’s not yet ready for use.

Drying Western Red Cedar for Exterior Applications

When drying cedar for outdoor use, it’s important to consider the climate it will be exposed to. Cedar that’s too dry may absorb excess moisture from the environment, leading to swelling and distortion.

Conversely, wood that’s too moist may shrink and crack as it dries out in the sun and wind.

Step-by-Step Guide to Air Drying Cedar

  • Select the Right Environment: Choose a dry, covered area with good airflow to stack your cedar. Avoid direct contact with the ground by using stickers (spacers) to elevate the wood and promote even drying.
  • Stacking the Wood: Place the cedar planks horizontally in layers, separated by stickers aligned vertically to create consistent spacing. Facilitate air circulation around each piece of wood with this approach.
  • Protecting the Stack: Cover the top of the stack with a tarp or roofing material to shield it from rain and direct sunlight, which can cause uneven drying and damage.
  • Monitoring Moisture Content: Regularly employ a moisture meter to monitor the moisture content of the wood. This will help you track the drying progress and determine when the cedar is ready for use.
  • Patience is Key: Keep in mind that air drying requires patience. Rushing the process can lead to poor-quality wood that may not perform as expected in your projects.

How to Cure Cedar Wood?

Curing cedar goes beyond simply waiting for it to dry. It’s about ensuring the wood acclimates to its environment and retains its natural beauty and strength. Here are some effective tips for curing cedar:

  • Avoid Overexposure: Too much sun or wind can cause rapid drying, which might lead to cracks or splits. Ensure your drying area is well-ventilated but not overly exposed.
  • Rotate the Wood: Periodically rotating the planks can promote more uniform drying and prevent warping.
  • Be Mindful of the Seasons: Start the drying process in the spring or early summer to take advantage of the warmer, drier weather. This can accelerate the drying process without compromising quality.

Summing Things Up:

In woodworking, patience is truly a virtue, particularly in the case of air-drying cedar. By understanding the nuances of the drying process and following a careful, methodical approach, you can ensure that your cedar reaches the perfect moisture content for your next masterpiece. 

Whether you’re building a cozy cabin retreat or crafting a set of elegant garden furniture, properly dried cedar will provide the durability and aesthetic you desire.

Remember, the journey from raw lumber to a finished project is a testament to your skill and dedication. 

Invest the time to dry your cedar properly, and it will provide you with years of beauty and functionality. Now armed with this knowledge, you’re prepared for your next woodworking project with confidence and expertise. 

Frequently Asked Questions

Cedar typically takes about one year to air dry properly, but this can vary based on thickness and environmental conditions. A moisture meter can provide an accurate moisture content reading.

Yes, cedar can get wet as it has natural water-resistant properties. However, it should be allowed to dry properly to prevent decay over time.

The time it takes for wood to air dry can vary, but a general guideline is approximately one year for every inch of thickness. Conditions like climate and wood species can affect this timeframe.

Cedar shrinkage varies by species, with radial shrinkage around 2.2% to 4.6% and tangential shrinkage approximately 4.9% to 6.9%, depending on the type of cedar.
