Understanding Snow Conditions: What the Reports Actually Mean

Snow condition reports are everywhere, but knowing what they actually mean is what separates a great ski day from a frustrating one. Here's how to read the numbers and make better decisions.

Base Depth vs. Fresh Snow

Base depth is the total accumulated snow on the mountain. A higher base means better coverage over rocks and thin spots, but it doesn't tell you what the surface feels like today.

Fresh snowfall (usually reported as the last 24 or 48 hours) is what really matters for day-to-day skiing quality. Even 5 cm of fresh snow can transform a mountain.

Snow Types

Not all snow is the same. Here's what you'll see on condition reports:

• Powder — Fresh, uncompacted snow. The dream. Light and easy to turn in.
• Packed powder — Groomed powder that's been compressed by machines. The most common and reliable surface for all levels.
• Groomed — Machine-smoothed runs. Consistent and predictable, great for carving.
• Hardpack — Dense, compressed snow. Fast but less forgiving. Sharper edges help here.
• Ice — Exactly what it sounds like. Common during freeze-thaw cycles or on heavily trafficked runs. Approach with caution and keep your weight forward.
• Spring snow / Corn — Granular snow caused by repeated melt-freeze cycles. Soft and fun in the morning sun, slushy by afternoon.
• Variable — A mix of conditions across the mountain. This is the resort's way of saying "it depends on where you go."

Temperature Matters

Temperature affects snow quality throughout the day:

• Below -15°C — Snow stays dry and fast. Great quality but dress warm.
• -15°C to -5°C — The sweet spot. Good snow preservation, comfortable skiing.
• -5°C to 0°C — Snow starts to soften, especially on south-facing slopes.
• Above 0°C — Spring conditions. Ski early when the surface is firm.

Wind and Its Effects

Wind is the underrated factor. Strong winds can:

• Strip snow off exposed ridges and deposit it in sheltered areas
• Create wind-packed surfaces that are hard and crusty
• Close upper lifts and limit terrain access
• Drop the wind chill dramatically

Check wind speeds before heading out. A calm day with 10 cm of fresh snow is better than a windy day with 20 cm.

How to Use This Information

1. Check Skicheck for current conditions at each mountain
2. Compare fresh snowfall across nearby resorts to find the best option
3. Factor in temperature trends — warming after cold means changing snow
4. Look at the forecast — conditions tomorrow matter as much as conditions today
5. Time your arrival — after a storm, go early before the fresh snow gets tracked out

The more you pay attention to conditions, the better your ski days become. Over time, you'll develop a sense for when and where to go based on the numbers.
