Spring 2026 Aerification Guide: When Your Favorite Seattle-Area Courses Are Punched and Playing Again

Spring in the Pacific Northwest means longer days, the return of evening rounds, and courses starting to come back to life. It also means aerification season.

Right when the weather turns and you’re ready to get back out there consistently, you might roll up to the course and see freshly punched greens. Not ideal… but necessary.

Golf Course Aerification

Why Courses Aerify Each Spring

Aerification (or aeration) is when courses punch small holes into the greens and remove plugs of turf. It might not look pretty, but it plays a huge role in keeping greens healthy.

This process helps relieve soil compaction, improve drainage, and allow air, water, and nutrients to reach the roots. In the PNW, most courses aerify twice per year, once in the spring and again in the fall, to keep greens in top condition year-round.

How Long Until the Greens Recover?

Recovery depends on weather and growing conditions, but here’s a solid rule of thumb:

Moderately Playable: ~7 days after aerification (Still a bit bumpy, but very playable)

Back to 100%: ~3 weeks (Smooth rolls, normal speeds, peak conditions)

If you’re flexible, this can actually be a great time to play. Courses are usually less crowded, and some offer discounted rates while greens recover.

Final Thoughts

Spring aerification is one of those necessary trade-offs. You might deal with a few bumpy putts for a week or two, but it’s what allows courses to be in great shape for the rest of the season.
