How to read the snow report

Snow depth (cm)

The total depth of snow lying on the ground, not the snow that fell that day. A high, stable depth means a solid base for the whole season.

Snow quality

Powder (cold and dry) skis best; heavy or spring snow comes with mild temperatures, rain or several sunny days in a row.

Wind and lifts

Strong gusts (from around 50–60 km/h) often close high chairlifts and gondolas for safety. Check the forecast wind before planning your route.

Temperature and snow cover

Nights below zero keep the snow in better shape; strong daytime sun can melt the surface and leave an icy crust in the afternoon, especially on south-facing slopes.

Mammoth Mountain weather: FAQ

How often is the Mammoth Mountain weather updated?

The forecast updates automatically several times a day with Open-Meteo data. Expected snow for the next 7 days is recalculated every time you open or refresh the page.

What does the snow depth on this page mean?

It is the depth of snow lying on the ground, in centimetres, not the snow that fell that day. A high depth does not always mean fresh snow: it can be old, compacted snow.

When is the best time to ski in Mammoth Mountain?

In the northern hemisphere the season usually runs from December to April, with the best snow in January and February when it is coldest. Opening and closing depend on each year’s snowfall.

How do I read snow quality?

Combine temperature, wind and fresh snow: below zero powder keeps, while mild temperatures or rain turn it heavy or icy. Strong wind can close high-altitude lifts.

Is the Mammoth Mountain data live?

The forecast (temperature, wind, expected snow) comes live from Open-Meteo. For open slopes and running lifts, always check the resort’s official website before going up.

Do I need to book ski hire in advance?

Yes, especially at weekends and in school holidays. Booking online means you collect your equipment in Mammoth Mountain, fitted to your level, without queuing in the shop.
