What There Is to Do in the Desert in September

Today, we cover:

Spa Month, and an events calendar with nothing on it. The official visitor site's weekend page lists no events at all — just a month-long spa promotion and a heat warning.
Two new artificial lagoons. A 5.5-acre surf pool in Palm Desert and a 24-acre Disney-built bay in Rancho Mirage, both open as of this summer.
An arena that ignores the season. Acrisure Arena has three concerts this month and just picked up a second professional sports tenant.
Death Valley's fourth-best year, achieved while partly closed. 1.32 million visitors in 2025, with roads still washed out.

Ask what there is to do in the Coachella Valley in early September and the tourism board will answer you honestly, which is unusual. Its events-this-weekend page for September 4–7 lists no individual events. What it lists instead is Spa Month, running valley-wide from the 1st through the 30th, and a standing advisory that daytime temperatures from June through October regularly exceed 100°F, with a recommendation to limit outdoor activity. The offering and the warning are the same sentence read twice.

The economics follow from the warning. Summer here is sold at a discount, and the summer 2026 slate reads like a list of concessions: up to 20% off at the Omni Rancho Las Palmas with kids eating free through September 7, a $49 daily food-and-beverage credit at the Saguaro, a $100 dining credit at the Thompson, and an ACME House Company offer that gives you two free nights on any stay of eight or more. Nobody discounts a room for eight consecutive nights in October. The rate is not a promotion so much as a price signal about what you are being asked to endure.

What the same press release announces alongside the discounts is more interesting: two large new bodies of water. DSRT Surf opened in Palm Desert as a 5.5-acre inland surfing lagoon, and Storyliving by Disney opened Cotino Bay Beach, a 24-acre lagoon ringed with dining and shops. Both are engineered surf-and-swim environments in a basin that gets roughly four inches of rain a year and draws most of its supply from the Colorado River and a stressed aquifer. Whatever you make of the water math, the design intent is unambiguous. The attraction is not the desert. The attraction is the thing installed on top of it.

Acrisure Arena makes the same point in a harder-edged way, because it does not pretend to be outdoors at all. The Palm Desert venue seats more than 11,000 and runs a conventional fall calendar — Chicago with Styx on September 2, Weird Al Yankovic on the 13th, MANÁ on the 26th, the B-52s and Devo on Halloween — and it has a schedule at all in September precisely because none of it happens under the sun. It already houses the Coachella Valley Firebirds, the American Hockey League affiliate of the Seattle Kraken. In April the Lakers announced their G League team would relocate here as well. An ice rink and two pro franchises in a place that hits 115 degrees is not a contradiction; it is the business model.

Then there is the actual desert, which is the one thing on this list nobody built, and which is currently the hardest to use. The National Park Service reported that Death Valley took in more than 1.32 million visitors in 2025, its fourth-highest year on record, and it did that while large sections of the park were closed. Flash flooding from storms in August, September and November scoured roads and shut down attractions including Artist's Palette. The park offered less access than usual and people came anyway, in near-record numbers, to look at rock and salt and distance.

That is the whole shape of the answer. Everything the valley markets in September — the spa, the lagoon, the arena, the discounted room — is capital spent to hold the desert a few feet away from you, and the summer rate is what it costs to sit behind that spending. The desert itself keeps drawing over a million people a season without a marketing budget, a roof, or, some months, a road.

The thing hardest to visit is the one nobody had to make.
