On Monday, Oct. 19, the Mission Hills Country Club calendar listed all three of its courses as closed for overseeding: the Dinah Shore Tournament course, the Pete Dye Challenge and the Arnold Palmer. Ten days later, the courses don't all reopen together. The club's calendar ends the closures in three stages a week apart, and that order decides which course carries the start of the 2026 season.
For households in Mira Vista at Mission Hills, those dates matter more than any general "overseeding ends in November" rule. By early November, the season's first tournaments are already booked on one course. The other two are still filling in.
The Order the Courses Come Back
Here is the order on the club's public calendar. The dates are the last day each course is listed as closed, not announced reopening dates.
- Pete Dye Challenge. Its last listed closure day was Thursday, Oct. 22. From Friday, Oct. 23, the calendar lists closures only for the Dinah Shore and Arnold Palmer courses.
- Dinah Shore Tournament course. Its last listed closure day is Thursday, Oct. 29.
- Arnold Palmer course. It stays on the closure list through Halloween weekend and into November. Its last listed closure day is Thursday, Nov. 5.
From Oct. 23 through Oct. 29, the Pete Dye was the only one of the three courses with no listed closure. From Oct. 30 through Nov. 5, two of the three are back and the Palmer is still out. The calendar shows all three available together only from Nov. 6, two and a half weeks after the closure list read three for three.
The full schedule is on the club's October calendar and November calendar. Calendars like these can change, so check the live page before booking a tee time around a date in this post.
Why the Courses Go Brown Before They Go Green
The stagger makes sense once you know what is happening on the fairways. The Desert Sun's explainer on overseeding season puts it simply. Bermuda grass thrives in the Coachella Valley summer but can go dormant and turn brown in winter. Courses seed cool-season ryegrass over it to stay green for the winter months. A local turf expert quoted in that 2017 article said the process works best when nighttime temperatures stay in the mid-60s. The article described courses closing for three to four weeks and reopening in November.
That pattern still holds. In October 2025, Desert Sun golf columnist Larry Bohannan wrote that overseeding shuts desert courses "for three weeks or more" to switch from summer Bermuda grass to winter grasses like ryegrass.
At a club with three courses, the closures don't have to happen all at once. Seeding them on a rolling schedule keeps some golf available for most of the window. At Mission Hills this fall, the full three-course shutdown on the calendar ended after Oct. 22. The rest of the window runs on fewer courses, never on none.
The Pete Dye Carries the Opening Weeks
Because the Pete Dye is back first, it hosts the first events of the season. Here is the early golf calendar for the first two weeks of November:
- Thursday, Nov. 5, 5 p.m. MGA Founders Pairing Party.
- Saturday, Nov. 7, 9 a.m. MGA Founders Golf Tournament on the Pete Dye.
- Monday, Nov. 9, 5 p.m. WGA Pairing Party.
- Tuesday, Nov. 10, 9 a.m. WGA Opening Day on the Pete Dye.
- Wednesday, Nov. 11, 11:30 a.m. MGA Play Day on the Dinah Shore Tournament course.
- Thursday, Nov. 12, 1:30 p.m. Finer Niners Play Day on the Pete Dye.
The men's founders tournament and the women's opening day both start on the Pete Dye. The Dinah Shore hosts its first group event on Nov. 11, six days after the Palmer's last listed closure day.
The Pete Dye has been a busy course this fall already. In September it hosted the APGA at Mission Hills, a 36-hole event in the Farmers Insurance Fall Series that was new to the APGA Tour. NBC Palm Springs reported on Sept. 16 that tour veteran Kevin Hall won the inaugural event. That puts the same layout at both ends of the off-season: a pro tournament in mid-September, then the first member events once the ryegrass is in.
What Fills the Days While the Palmer Waits
From Oct. 29 through Nov. 5, while the Palmer is the last course still closed, the club calendar fills the gap with equipment demos, clinics and dining. Most of it is booked through the members' registration system, so it is aimed at members and their guests.
- Pizza & Vino in The Fifty-Fifth runs Thursday, Oct. 29, from 3 to 8 p.m. It is the last date of a series that ran every Thursday in October, with reservations through the dining page.
- Club to Home offers chef-prepared three-course meals for dining at home, listed nightly from 5:15 p.m. through the end of October.
- Demo days fill the stretch: Icon Golf Cars on Oct. 30 and 31, Callaway on Oct. 30, PXG on Nov. 3, XXIO on Nov. 4, Titleist on Nov. 6 and Cleveland/Srixon on Nov. 7.
- Weekly clinics with David Mulso continue on Friday, Oct. 30. The 8 a.m. Full Swing clinic and the 10 a.m. Beginner Golf Series each cost $40 per person and meet at the front of the driving range. The calendar describes both as open to all membership and guests, and the beginner session is limited to six people.
Then the social season starts. The Opening Party 2026, "Moulin Rouge!", is set for Sunday, Nov. 8, at 5 p.m., at $68++ per person. The next morning, Monday, Nov. 9, the calendar lists an Eisenhower Flu Clinic at MHCC at 9:30 a.m. On Friday, Nov. 13, the Corkpullers Tasting & Dinner, "Around the World in 5 Glasses," begins at 6 p.m.
The club's dining page names the kitchen team behind these events: Chef Mark Samson, The Fifty-Fifth, and Champions Bar & Craft Kitchen. The opening party lands on Nov. 8, three days after the Palmer's last listed closure day. On the current calendar, the club has all three courses back before it opens the social season.
The Water Behind the Green
Overseeding has a cost that golfers never see. The 2017 Desert Sun explainer reported that local golf courses use about 750,000 to 1 million gallons of water per day on average over the year. It also noted that the new ryegrass needs heavy irrigation to germinate.
That is why the green fairways of early November are under study. In May 2025, GCSAA's GCM magazine reported on the Coachella Valley Golf and Water Task Force. The task force is a partnership between the water district and the valley's 121 golf courses. Some courses are converting turf to less thirsty grasses such as TifTuf, and newer strains that stay green longer could reduce the need to overseed at all. The magazine quoted Kessler, a task-force representative:
"Avoiding overseeding is probably the direction that is going to ultimately save the most water."
Nothing on the Mission Hills calendar points to a change in its own program. This fall it is overseeding all three courses on a rolling schedule. The task force's work covers all 121 courses in the valley, including the fairways around Mira Vista.
If you are planning around this season, whether that means hosting guests, timing a listing photo shoot for green fairways, or deciding when the house should be ready for winter, The Downs Team follows the Mission Hills calendar closely and can help you pick the week that fits.
