SNOWSURE™
Know before you book. Know before you go.
Why SnowSure exists
The question every client asks before they commit to a ski holiday: how do we actually know there will be snow?
It comes up on every planning call. It is the most reasonable question in ski travel, and for years the honest answer was uncomfortable: you don't. You read the resort's marketing, you checked a weather app that wasn't built for mountains, and you hoped.
SnowSure is our answer to that. Not editorial opinion — a platform built on data. Seven of the world's leading weather models, thirty years of historical snowfall records, and an AI system that learns which forecasts to trust by region and by season. It produces a single score for each resort, updated continuously, that tells you what no single model and no resort website will: whether the conditions are genuinely worth going for.
It also exists for the planning decision that happens long before any forecast is useful — when you're choosing a resort and a travel window months out, and the forecast simply doesn't exist yet. That's where the historical data becomes the product.
How SnowSure works
Seven models. Thirty years. One score.
SnowSure combines data from seven leading meteorological agencies — ECMWF (European), GFS (American), GEM (Canadian), JMA (Japanese), ICON (German), Météo-France, and Met Norway — and continuously tracks which models have been most accurate for each resort region and forecast horizon. The result is a weighted forecast that improves with every storm analysed, not a static snapshot from a single source.
That data, combined with current conditions, snowpack depth, recent snowfall, and thirty years of historical patterns, produces the SnowSure Score: a single 0–100 number that answers the question directly. 85 and above means go. Below 50, we'll tell you which resort nearby is scoring better.
The system learns. Every forecast SnowSure makes is tracked against what actually fell. That verification loop is what makes it more accurate over time — and what makes it different from every other tool available to skiers.

Ranked by overall conditions and forecast
Two decisions SnowSure is built for
Before you book
The historical question
Six months out, no forecast exists. What does exist is thirty years of data on what actually fell at each resort, by week of the year, at each elevation. SnowSure surfaces that data clearly: which resorts are statistically reliable in your travel window, which weeks are consistently strong, and which are a gamble even in a good year. This is how we advise on resort selection and timing before any commitment is made.
Before you travel
The forecast question
As your trip approaches, the SnowSure Score gives you a live read on conditions — updated every fifteen minutes from seven active weather models. We'll tell you whether the week looks like an 89 or a 54, and what's driving the difference. If conditions are exceptional, we'll tell you that too.
How we think about snow
01
Altitude is the only reliable guarantee
A famous resort at 1,200m is a measurably worse bet than a lesser-known one at 1,800m. SnowSure maps every resort by guaranteed snow altitude, not reputation or marketing claims. The numbers don’t negotiate with brand image.
02
Which week you travel matters more than which month
Seasonal averages hide the truth. January is not uniformly reliable. March is not uniformly risky. SnowSure’s historical data shows which specific weeks have delivered consistently over thirty seasons — and which ones carry real uncertainty even at altitude.
03
Aspect determines how long snow lasts
North-facing terrain holds snow significantly longer than south-facing. When snowfall is marginal, the difference between a good week and a mediocre one often comes down to which part of the mountain you’re on. SnowSure identifies which areas of each resort stay skiable longest when conditions aren’t perfect.
04
Cover exists, but only if you understand it
Not every travel insurance policy covers poor snow conditions. We explain which protections apply, what the triggers are, and what your options are if a trip needs to change. Knowing this before you book changes the risk calculus entirely.
