Understanding Snow Reports and Conditions

A snow report is a resort's daily bulletin on conditions — snowfall, base depth, grooming, wind, visibility, and avalanche risk. Learning to read one properly helps you pick the best day to ski, choose the right runs, dress appropriately, and avoid dangerous conditions. Yet most skiers glance at a single number (new snow) and ignore everything else. This guide teaches you to decode every element of a snow report, understand what different snow types feel like underfoot, and use forecasts to plan your week for maximum enjoyment.

Anatomy of a Snow Report

Most resort snow reports, whether on the resort's own website or aggregated by platforms like SkiPlnr, contain the same core data points. Understanding each one transforms a snow report from a confusing grid of numbers into a clear picture of what awaits you on the mountain.

New Snowfall (24h / 48h / 72h)

This is the headline figure that gets skiers excited. It tells you how much fresh snow has fallen at various measurement points (usually summit and base) in the last one, two, and three days. Here's how to interpret it:

• 0–5 cm: A dusting. Groomed runs will ski well but there's no powder to be found off-piste.
• 5–15 cm: A decent refresh. Groomed runs will have a nice soft top layer. Sheltered north-facing slopes may hold pockets of soft snow for a few turns.
• 15–30 cm: A proper snowfall. Ungroomed terrain will have genuine powder. Early morning first tracks on ungroomed runs will be excellent.
• 30–60 cm: A storm cycle. Deep powder on all ungroomed terrain. Lower-ability skiers should stick to groomed runs, which will be soft and forgiving. Strong skiers should head for off-piste terrain - but check the avalanche bulletin first, as heavy snowfall dramatically increases avalanche risk.
• 60 cm+: A significant dump. Lifts may be delayed opening due to avalanche control work. When they do open, conditions will be extraordinary - but deep snow is physically demanding and requires specific technique.

Base Depth

Base depth is the total accumulated snow pack, measured at a fixed point (or averaged across several). It tells you about the season's overall health rather than today's conditions. A base of 60–80 cm is the minimum for comfortable skiing without rocky patches. Most well-run resorts maintain at least 80 cm through a combination of natural snow and snowmaking. Don't compare base depths between resorts blindly - measurement methods vary, some resorts report settled snow (compressed) while others report total snow depth (fluffier), and wind redistribution means the snow on the slopes you actually ski may be very different from the weather station reading.

Temperature

Temperature at summit and base tells you several things: what to wear, what the snow texture will be, and whether there's a freeze-thaw risk. Key thresholds:

• Below -15°C: Cold. Snow is very dry and fast, but exposed skin freezes quickly. Wear a balaclava and chemical hand warmers.
• -15°C to -5°C: The sweet spot. Snow holds its structure, groomed runs are firm and fast, and it's comfortable to ski all day with proper layering.
• -5°C to 0°C: Marginal. Snow may soften in the afternoon sun on south-facing slopes. Good morning skiing, potentially heavy or sticky snow by 2 PM.
• Above 0°C: Spring conditions. Snow becomes slushy by midday, especially below 2,000 m. Ski early mornings (hard-packed, fast) or embrace the slush. Lower runs may close if the snowpack deteriorates.

Snow Types and What They Mean for Your Skiing

Snow reports often describe conditions using specific terminology. Here's what each type actually feels like underfoot and how to adjust your skiing:

Powder

Fresh, uncompressed snow. The holy grail. Light powder (cold, dry, high-altitude snow as found in Utah, Japan, or high Alpine resorts) floats around your knees and requires a centred stance with even weight distribution. Heavy powder (wetter, denser, lower-altitude snow common in the maritime Alps) is more physically demanding and requires strong leg muscles and a more aggressive forward stance. Both types reward skiers who commit to the fall line and maintain speed - going too slowly in powder leads to getting stuck.

Groomed / Corduroy

The most common surface. Freshly groomed runs have parallel ridges (corduroy) left by the piste basher's tiller. This is the most predictable, easiest-to-ski surface and what most ski school lessons take place on. It deteriorates through the day as skier traffic chops it up, so morning grooming is best.

Packed Powder

Snow that's been compressed by traffic or grooming but retains a soft, consistent texture. This is what most runs feel like by mid-morning on a normal day - firm enough for good edge grip but soft enough to be forgiving if you catch an edge. Excellent all-round conditions.

Crud

Chopped-up, inconsistent snow left after powder has been partially skied out. One moment your skis float, the next they catch on a dense clump. Crud is physically tiring and requires a strong, centred stance with active absorption in the legs. It's the most common surface on ungroomed terrain 24–48 hours after a snowfall.

Ice and Hardpack

Snow that's been compacted and then frozen into a hard, slippery surface. Common on heavily trafficked runs, artificial snow slopes, and anywhere that sees freeze-thaw cycles. Sharp ski edges are essential - dull edges will slide on ice. Reduce your speed, make deliberate edge-set turns, and avoid sudden movements. Ice is the surface most beginners find scary, and rightly so - consider switching to less popular runs where traffic hasn't scraped the snow away. See our difficulty ratings guide for how ice changes the effective difficulty of any run.

Spring Snow / Corn

A late-season phenomenon. Overnight freeze hardens the top layer, then morning sun softens it into a smooth, creamy surface called corn snow. The window of perfect corn is typically 10 AM to 1 PM on south-facing slopes - before that it's icy, after that it's slush. Timing is everything in spring skiing, and experienced skiers chase the sun around the mountain, skiing east-facing slopes first, then south, then west.

Wind - The Most Underrated Factor

Wind is the condition most likely to ruin your ski day, and it's the one most skiers ignore. Here's why it matters so much:

• Lift closures: Exposed chairlifts and gondolas close when wind speeds exceed safety thresholds (typically 60–80 km/h). Resorts at high altitude or on exposed ridgelines are most vulnerable. When upper lifts close, every skier is funnelled onto the lower slopes, creating crowds and queues.
• Windchill: A temperature of -10°C with a 40 km/h wind creates an effective temperature of -25°C on exposed skin. This causes pain within minutes and frostbite risk on any uncovered area. Check windchill forecasts and dress accordingly - a balaclava, goggles (not sunglasses), and insulated gloves become essential.
• Wind slab: Wind deposits snow on lee slopes, creating dense, cohesive wind slab that's one of the most common avalanche triggers. If the snow report mentions strong winds, off-piste skiers should be extremely cautious on wind-loaded aspects.
• Visibility: Wind lifts surface snow (spindrift), reducing visibility dramatically even when it's not actively snowing. Combined with flat light (overcast skies), this creates near-whiteout conditions where you can't see the terrain ahead.

Before heading out on a windy day, check which lifts are open, plan routes that use sheltered lifts and tree-lined runs, and dress for the windchill rather than the base temperature.

Visibility and Light

Visibility is reported in categories: clear, good, moderate, poor, or whiteout. It affects your skiing in practical ways:

• Clear / good: Full sun or high cloud. You can see terrain features, read the snow surface, and judge speed. Wear sunglasses or light-tint goggles.
• Moderate: Overcast with some definition. You can ski normally but may misjudge bumps and dips. Switch to orange or yellow-tint goggles for better contrast.
• Poor / flat light: Low cloud, fog, or heavy overcast. The snow and sky merge into a featureless white. Bumps are invisible until you hit them. Stick to tree-lined runs where the trees provide reference points and contrast. Avoid wide-open above-treeline bowls.
• Whiteout: Effectively zero visibility. Navigation is guesswork. Stick to groomed pistes where marker poles guide you, or call it a day and enjoy the après-ski early.

Avalanche Bulletins

If you're skiing off-piste, the avalanche bulletin is the most critical part of the snow report. Published daily by national avalanche services (Météo France, SLF in Switzerland, EAWS across Europe), bulletins use a standardised five-level danger scale. We cover this in depth in our avalanche safety guide, but the headline levels are:

Even if you ski exclusively on pistes, awareness of avalanche danger is useful - at level 4 and above, even pistes in exposed locations may be closed or rerouted.

Using Snow Reports to Plan Your Week

Smart skiers don't just check the report each morning - they use multi-day forecasts to plan their entire week. Here's a practical approach:

1. Sunday evening: Review the week's forecast. Identify the best and worst days for weather and snowfall.
2. Storm days: If a big snowfall is forecast for Tuesday night, plan an easier day on Wednesday morning (lifts may open late for avalanche control) then hit ungroomed terrain once the lifts are clear.
3. Rest day timing: Take your rest day on the worst weather day. Most skiers take Wednesday off by default, but if Thursday looks like a storm, ski Wednesday and rest Thursday.
4. Afternoon deterioration: In warm weather (late season, south-facing slopes), ski the high terrain and north-facing aspects in the afternoon when lower slopes turn to slush.
5. Wind patterns: If strong wind is forecast for the morning but dropping in the afternoon, start on sheltered lower slopes and head high once the upper lifts reopen.

Bookmark your resort's official snow report page, install any resort app that sends push notifications for snowfall, and check aggregator sites like SkiPlnr's when to visit pages for historical averages. Building a habit of reading snow reports thoroughly - not just glancing at the new-snow number - will make you a smarter, safer, and more adaptable skier.

Key Takeaways

• New snow in the last 24/48/72 hours is the headline figure — 20 cm+ of fresh snow means powder conditions on ungroomed terrain
• Base depth matters less than you think — 80 cm of well-packed snow is perfectly skiable even if a neighbouring resort reports 200 cm
• Wind is the most underrated factor: strong wind closes upper lifts, creates dangerous wind slab, and makes windchill brutal
• Avalanche bulletins use a 1–5 scale. Level 3 (Considerable) and above means off-piste conditions are genuinely dangerous
• Check reports at 7–8 AM for the most accurate overnight data, then again at midday for updated lift status

Frequently Asked Questions

When is the best time to check the snow report?

Check the report between 7 and 8 AM, when resorts publish overnight snowfall, grooming status, and expected lift openings. Check again at 10–11 AM when all lifts have been assessed and wind holds or closures are confirmed. Weather forecasts for the afternoon and next day are most accurate from midday onwards.

What does 'base depth' actually mean?

Base depth is the total accumulated snow pack measured at a specific point (usually mid-mountain). It includes natural and artificial snow, compacted by its own weight over the season. A base of 80–100 cm is generally sufficient for good skiing on groomed pistes. Very high base depths (200 cm+) indicate excellent seasons but don't necessarily mean better day-to-day skiing.

What's the difference between powder and packed powder?

Powder is fresh, uncompressed snow that has fallen recently and not been groomed or skied. Packed powder is snow that has been compressed by grooming machines or skier traffic into a firm, smooth surface. Groomed packed powder is the most common surface you'll ski on and provides predictable, easy-to-ski conditions.

Should I ski in a storm?

Light snowfall during the day creates magical conditions — fresh tracks with good visibility. Heavy snowfall (5+ cm per hour) combined with wind creates whiteout conditions, which is dangerous for navigation and uncomfortable. In a heavy storm, stick to lower, tree-lined runs where visibility is better and shelter from wind is available.
