Las Vegas overseeding 2026: what closed, what reopened, and what to expect in 2027
Golf Summerlin's three courses and Las Vegas National closed in September and reopened on the dates they published. Most of the valley published nothing at all. Here is the 2026 record, what it did to the fall season, and the window to plan around in 2027.
Update, 26 October 2026 — how the season played out
This page is now the record of the 2026 overseeding season, kept at the same address because it is where people found it. The four confirmed closures have ended. The text below is what we published on 12 September, left as written, followed by what happened next and what to expect in 2027.
What we published on 12 September
It is the second week of September, which in Las Vegas means the grass is being changed. Overseeding closes courses across the valley every autumn, usually for two to three weeks, and it is the single most common reason a booked round falls through this month. The problem is not the closures. The problem is that hardly anyone publishes them.
We read every Las Vegas operator's own website on 12 September. Two publish their overseeding dates plainly. The rest publish nothing.
What was closed
Confirmed closures — read from operator sites, 12 September 2026
Golf Summerlin runs the three municipal-priced courses at the top of the valley, and it posts the same notice on all three course pages, word for word:
Overseed 2026: Eagle Crest, Highland Falls, and Palm Valley Close Tuesday, September 8 Open Tuesday, September 29 / No Cart Path Restrictions
That last clause matters more than it looks. Most courses come back from overseeding on cart-path-only rules for a week or more while the new turf roots, which on a desert layout with long green-to-tee walks is a different round entirely. Golf Summerlin is telling you in advance that it will not be doing that.
Las Vegas National — the 1961 Bert Stamps course on Desert Inn Road, opened as the Stardust Country Club — is the other one that says so, on its homepage:
COURSE UPDATE: Closed for Overseeding – Reopens (Cart Path Only) Saturday, Sept. 26, 2026. RANGE UPDATE: Closed for Overseeding – Reopens on Saturday, Sept. 26, 2026
Note that the range is closed too. If you were planning to warm up somewhere central before an afternoon round elsewhere, that option is gone until the 26th.
Everyone else, as of 12 September
On 12 September we read the public pages of TPC Las Vegas, Angel Park, Bali Hai, Rhodes Ranch, Las Vegas Golf Club, Desert Rose (The Club at Sunrise), The Legacy and Painted Desert, looking for any overseeding, closure or cart-path notice. We found none on any of them.
That is not the same as saying those courses are open and in summer condition. Almost every bermuda course in the valley overseeds, and mid-September is when it happens. What it means is that the information exists only inside a booking engine or on the end of a phone line. A notice that appears at the moment you try to pay is not a notice.
So the honest summary is: two courses have told you, and the rest have not. Call before you drive.
What overseeding actually does to a round
Las Vegas courses are planted on bermudagrass, which goes dormant and brown when night temperatures fall. To stay green and playable through the winter, the course is scalped down, seeded with perennial ryegrass over the top, and then watered heavily until the rye germinates. The course has to be closed for that, because carts and spikes on wet seed undo the whole exercise.
Two to three weeks is the normal window, which matches what both operators here published. What follows the reopening is the part that catches visitors out: soft, wet fairways, cart-path-only rules, temporary greens in some cases, and mowing patterns that have not settled. The course is open. It is not the course you saw in the photographs.
Not everywhere overseeds. Some courses have moved to strains that hold colour, and the higher-end resort operations sometimes stagger nines so they never fully close. If you are booking between now and mid-October, that is the single question worth asking: not "are you open" but "have you overseeded, and are you on cart paths."
How it played out
- 26 September: Las Vegas National reopened, cart path only, and its fall rate card started the same day — the non-resident rate moved from $109 to $179, which we covered separately.
- 29 September: Golf Summerlin reopened Eagle Crest, Highland Falls and Palm Valley, and said in advance its carts would go on the grass from day one.
- 26 October: we re-read both operator sites. Neither carries a closure, overseeding or cart-path notice any more. The season is over for the courses that announced it.
- The rest of the valley never published a date. If you booked through a third-party site in mid-September and arrived at a closed course, this is why.
What to expect in 2027
Overseeding is tied to night temperatures, not the calendar, but in Las Vegas it lands in the same window almost every year: closures begin in the second week of September and courses reopen in the last week, usually on cart-path-only rules for a further week or two. The two operators that publish dates have been consistent, and we expect Golf Summerlin and Las Vegas National to post their 2027 windows in late August. We will add them to this page the day they appear, and every other operator's as soon as one is published.
If you are planning a Las Vegas golf trip for September 2027, the practical rule has not changed: the last week of August and the first week of September are safe, the middle two weeks of September are not, and from the first week of October every course in the valley is open again, green, and briefly softer than usual.
If you run a course in the valley and want your 2027 window listed here, tell us and we will add it with a link to your notice.
Frequently asked questions
Which Las Vegas golf courses closed for overseeding in 2026?
Four were confirmed from their operators' own sites. Eagle Crest, Highland Falls and Palm Valley, the three Golf Summerlin courses, closed on Tuesday 8 September and reopened Tuesday 29 September 2026. Las Vegas National reopened Saturday 26 September 2026, cart path only. No other Las Vegas operator published an overseeding notice on its website during the 2026 season.
When do Las Vegas golf courses overseed?
Mid-September to early October. In 2026 the published closures ran from 8 September to 29 September. Most valley courses close for two to three weeks in that window, then reopen on cart-path-only rules for a further week or two. Expect the same pattern in 2027; we will post operator dates here as they are published.
Are the Las Vegas courses that closed for overseeding open again?
Yes. Golf Summerlin's three courses reopened on 29 September 2026 and Las Vegas National on 26 September 2026, on the dates each operator published. When we re-read both sites on 26 October 2026, neither carried a closure or cart-path notice.
Why do Las Vegas golf courses close in September?
Overseeding. Valley courses are planted on bermudagrass, which goes dormant and brown as nights cool. Each autumn the course is scalped, seeded with perennial ryegrass and watered heavily so it stays green through the winter. Play has to stop for roughly two to three weeks while the seed germinates, and cart-path-only rules usually follow for a while after reopening.
How do I find out if a course is overseeding if it does not publish dates?
Call the golf shop directly. Third-party booking sites are the last to be updated and will sell tee times at closed courses. Ask two questions rather than one: whether the course has overseeded, and whether carts are restricted to paths. A course can be open and still not be the course you were expecting.
