As reported by the Mammoth Snowman & Team.
4-8-2026 – Snow Report: Expect spring conditions through Wednesday. The groomers are a fast, firm surface to start the day, and by mid-morning the spring corn takes over.
There have now been several freeze-and-thaw cycles, so the snow has come back up. The next few days should be sweet as the firm snow softens into the nice, soft, lovely corn snow. Yahoo…
Up top, the snow has been hard-pressed to convert. You will find the snow firm up there into the latter morning hours, and then runs in the direct sun turn over to some nice early April corn. Cornice and Scotties are groomed and make for some fast, firm carving, but they convert over to spring snow.
If you’re out early over the next few days, seek out runs in the sunshine and avoid the shade. Make sure you’re waxed up, or you will get that spring sticky feeling on your skis.
Moving forward, the season is over for chairs 7, 9, 15, 22, and 25. The Canyon Lodge area groomers, for the most part, still have plenty of snow, but you will notice the base in that area has taken a big hit.
Unbound Parks is still going strong, with full setups at South Park, Forest Trail Park, and the Main Unbound Park.
If you’re wondering how long Mammoth will stay open this season, they plan to remain open until Memorial Day. However, to make that happen, the ski area needs the weather to cool off over the next 2 months and more snowfall.
Ski ya later, Snowman out

🍂 Mammoth Mountain Snow Report — Fall FAQ
1. When does Mammoth Mountain usually open for skiing?
Mammoth typically opens the Friday before Veterans Day. The exact date depends on natural snowfall and snowmaking conditions. In some seasons, an early winter hits with major footage in October. The mountain has opened as early as October 7th. One year open day was 10/7
2. When does Mammoth Mountain usually start making snow?
Crews are typically on site by mid-October, setting up lines and towers. Once the third week of October passes, they’ll fire up the guns whenever a cold air window appears.
3. How cold does it need to be for snowmaking at Mammoth?
The Wet-Bulb Temperature determines ideal snowmaking conditions. When it’s in the low to mid-20s, it means the Mammoth Mountain Snowmaking Crew can make lots and lots of snow. Learn more at our Mammoth Mountain Snowmaking Page.
4. Which runs get snowmaking first?
There’s a set priority that’s followed almost every year:
- Broadway
- Lower Unbound section
- Saddle Bowl for Chair 3
- The wraparound to Rusty’s and Fascination (for race camps)
- Sesame Street for Chair 11
- Then Unbound Main and Forest Trail down to The Mill
- Stump Alley comes next
This sequence ensures an opening-day base out of Main Lodge, terrain for early camps, and connections to the Mill and Mill Parking area as quickly as possible.
5. Can you ski at Mammoth during Thanksgiving?
Yes. Mammoth almost always offers skiing and riding by Thanksgiving, thanks to consistent early snowmaking. Terrain may be limited in lean years, but the resort prioritizes having multiple lifts and lodge access open during the holiday. If possible, they plan to have Canyon Lodge open for Thanksgiving 2025.
6. How reliable is snowmaking at Mammoth?
Snowmaking is a significant operation at Mammoth, usually running from late October through February. Even in low-snow years, snowmaking ensures skiing for the holidays.
7. What is the average snowfall during November and December
In November, 29 inches. December typically receives 67 inches of snow, with the most significant amount recorded in 2021 at 161 inches.
8. When does the upper mountain open for the season?
The upper mountain needs a good 3-4 foot base storm to kick things off. When does that happen? Every single year is different; there is no average. What I can tell you is that most years (70%), by Thanksgiving, they have at least one Cornice Bowl open.

There’s nothing worse than some crybaby complaining that our conditions are not right. Yep, I get emails like that. Again, read the date, and don’t be a jerk.

Third, what Snowman or any other member of the www.mammothsnowman.com community posts is purely based on how that person views snow conditions.
Everyone has their own perspective, so one person’s epic day might not be your epic day. For example, I love the taste of spring corn snow, but many people dislike it.
Fourth, you can die skiing or snowboarding. If you’re not skilled, don’t take the runs; Snowman or somebody else in the community might suggest them.
Many of our videos contain extreme footage of professional athletes who ski and ride full-time. We do not endorse these activities and encourage you not to attempt the tricks and extreme moves that professionals perform in our videos or images.
