St. George, Utah Golf Overseed Schedule: Which Courses Close When, and Which Stay Open

The St. George golf overseed schedule runs from late August to early October. In 2026 the four City of St. George courses closed in turn between Sept 8 and Oct 6, Green Spring in Washington closed for most of a week in late September, and the Mesquite, NV courses closed for three to five weeks each. Coral Canyon and Black Desert don't overseed at all, but Black Desert in Ivins closes for its PGA TOUR event in the same window.

If you're planning a September or early October golf trip to St. George, Utah, the dates below decide where you can play.

Why St. George golf courses close every fall

Most courses in Washington County and Mesquite are bermudagrass. Bermuda loves heat but goes dormant and brown in winter, so each fall courses seed ryegrass over it to stay green until spring. To do that they close completely, usually after a day or two of aeration, while the new grass gets established.

St. George's city courses are typically closed about two weeks. Mesquite courses are typically closed about a month. After reopening, many stay cart-path-only for a few days to a few weeks while the new grass fills in.

The payoff is a green course from November to March. At St. George Golf Club, the city says the tees, fairways and greens stay rich green through those months while the rough, which isn't overseeded, goes brown.

2026 St. George golf overseed schedule

Dates come from each course's official maintenance page or the City of St. George 2026 schedule, except where noted.

Mesquite, NV and the Arizona line:

Wolf Creek's 2026 closure was preceded by spraying the course into dormancy from Aug 25 to Sept 1, and its 2025 closure was Sept 2 to 25, so the dates can move by more than a week from year to year.

Courses that don't close for overseed

A few courses skip the fall closure, which makes them the anchor of any September trip.

• Coral Canyon in Washington (course guide) grows bentgrass greens and Kentucky bluegrass and ryegrass fairways all year, so it doesn't overseed. Its published aeration closures are in May (May 5–7) and August (Aug 18–20), but the year on those dates isn't stated.
• Black Desert in Ivins is creeping bentgrass from tee to green with bluegrass rough, so there's no bermuda to overseed. It does close in mid-September to early October for the PGA TOUR, and in 2026 it played on mats with limited tees from Aug 1 to Sept 13.
• Sand Hollow in Hurricane (course guide) publishes no overseed closure. It aerifies greens in early May and August and tells golfers to call for exact dates.
• Sky Mountain, also in Hurricane, has no fall overseed closure on record; its aeration has been listed in early May.

We found no overseed dates for The Ledges, Copper Rock or Entrada, so call those courses before booking a September round.

Where to play in September, by part of town

Overseed season changes the map. Here's how the open courses fell by area in September 2026, with drive times from downtown St. George.

The east side is the safe bet. Coral Canyon is about 17 minutes from downtown, and Sand Hollow and Sky Mountain about 28 to 32 minutes, out toward Zion National Park. The Hurricane and Sand Hollow golf guide and Washington, Utah golf guide cover those courses, and golf near Zion National Park is useful if you're combining the two.

September 2026, week by week

Here's how the closures stacked up. Use it as a pattern for next year, not a promise.

Reading the city schedule closely, Sept 22 was the one day in 2026 when all four City of St. George courses were closed at once. For the rest of the window at least one city course, and usually two, was open.

In Mesquite, the Oasis pair is staggered on purpose: the Canyons closed two weeks before the Palmer and reopened a week earlier, so in late September or early October one of the two is usually open.

What about 2027?

Most 2027 overseed dates weren't published when we checked in October 2026. The one exception: Golf Zoo lists Falcon Ridge's 2027 closure as Sept 7 to Oct 2. The 2025 and 2026 patterns suggest the city courses will again close in turn from the second week of September into early October, and Mesquite courses from late August or early September for about a month. Check each course's maintenance page in summer before you book.

For a longer view, a 2022 Mesquite schedule ran Canyons Sept 4–30, Conestoga Sept 6–Oct 3, Wolf Creek Sept 6–29, Falcon Ridge Sept 12–30 and Palmer Sept 15–Oct 15. The window is consistent; the exact days are not.

How to check next year's St. George golf overseed schedule

The dates move every year, so treat any published St. George golf overseed schedule as good for one season only. Where to look:

• City of St. George courses: the city posts an annual golf maintenance schedule PDF covering aeration and overseed for Sunbrook, St. George Golf Club, Southgate and Dixie Red Hills.
• Green Spring: Washington City puts its closure and cart-path-only dates on the course rates page.
• Mesquite courses: Wolf Creek, Conestoga, Oasis and Falcon Ridge all posted 2026 closures on their own sites. Golf Zoo also lists Mesquite dates, though its days sometimes differ from the course's by one or two.
• Private and resort courses set their own schedules, so call.

When you call, ask three things: the closure dates, how many cart-path-only days to expect after reopening, and whether the range stays open. Prep can start before the closure itself; Oasis, for example, starts drying out the course 10 to 14 days before it shuts.

Spring aeration: the smaller closure

The fall overseed isn't the only disruption. The city runs spring aeration from mid-April to mid-May with partial openings. In 2026:

• St. George Golf Club: Apr 15–16, 9 holes open
• Southgate: Apr 27–28, 9 holes open
• Dixie Red Hills: closed Apr 27, open half a day Apr 28
• Sunbrook: May 12–14, 18 holes open

These rarely wreck a trip, but freshly punched greens putt badly for a week or two.

How to plan a September or early October trip

1. Build around the courses that don't close. Coral Canyon and Sand Hollow are the safest anchors on the Utah side.
2. Use the stagger. In mid-September 2026, St. George Golf Club and Southgate were open while Sunbrook and Dixie Red Hills were closed. Two weeks later it flipped.
3. Expect crowds and cart paths. With fewer courses open, the open ones get busier, and freshly reopened courses may be cart-path-only.
4. Mind the early-October events. The PGA TOUR event, the St. George Marathon and the Huntsman World Senior Games all fell in the first two weeks of October in 2026, when hotels were at a premium.
5. Or wait a few weeks. By November everything has reopened and settled. See November golf in St. George.

The upside of September: city courses still charge their summer rate through the month, and highs drop to about 92°F. See the best time to golf in St. George, summer golf deals in St. George and Mesquite, Nevada golf courses for more.
