Snow: Forecasting, Reporting, Season/YTD, Operations & more

Overall, I am not really interested in snow forecasting. There are so many sites and models, and some even do a decent job.

However, I have grown tired of inflated, inaccurate snowfall data from pervasive, cheap, easy-to-plug-in API services. These are the culprits:
  • Snow-Forecast API
  • Open-Meteo API
  • OnTheSnow API
  • Synoptic Data API

I am interested in the facts around a storm, so I decided to bypass all of the above and just web/data/html scrape the following attributes I am interested in:
  • New Snowfall
  • Year-To-Date or Historical Snowfall
  • Current Snow Base (Various Locations)
  • Operations - Lifts (Specifically lifts that serve unique terrain or run less frequently)
  • Operations - Pistes or Trails
  • Wind Speed - Avg, Max
  • Avalanche Danger - Daily Rating
Since I don't know how often or when ski resorts update this information, I am grabbing it hourly (often defaulting to the max snow/operations/wind/etc per 24-hour period). Maybe once a day if I can see an update pattern.

I created different apps with tools from Lovable, Anthropic, OpenAI, and others. Basically, I'm making dashboards with drill-down details.

I picked about 30-40 resorts to focus on in the Southern Hemisphere in Chile, Argentina, New Zealand, and Australia.

Again, snow arrived really late everywhere in the Southern Hemisphere, so I'm still working with limited data and results.

However, I want to be able to answer questions:
  • When was Marte open at Las Lenas, and for how many days?
  • How often were all 4 slingshot lifts open at Portillo?
  • How often was Mt Hutt essentially closed?
  • How much snow in the last 2 days, week, or month?
Again, I do not really care about 100% accuracy. I just want to accurately aggregate reported data from a legitimate source. For the Alps, many resorts report this information, but I will also use government or reputable NGO sites.


Anyway, I am playing around with how to show most of the snow conditions below. Operational interest is only in expert-oriented lifts/slopes that open less often. Examples: Las Lenas, Portillo, Nevados de Chillán, Corralco, etc

In North America, I might be interested in Fernie's Polar Peak lift, Squaw's Silverado, Crested Butte's North Face terrain. The Alps, mostly if specific lifts are open/closed.

Data I am collecting from mid-July

This sounds like a very worthwhile project that is beyond my software skills. I’m not going to look at details above while on my phone in Spain though.

You can track key/vulnerable lifts open/closed? Here’s some more I’d like to see:
Summit at Bachelor
Red chair at Castle
Pali at A-Basin
Kachina at Taos
Imperial at Breck
Gondola 2 at Mammoth
Peak chair at Whistler

Not a lift per se but Delirium Dive at Sunshine
