Windy is great. The map is appealing, but be sure to check out the forecast view for a particular location. Also make sure you try different locations. I'm in the Salish Sea on Orcas Island in the San Juans and because we have a lot of topography here mixed with ocean, we have a lot of local effects, contour winds and so on and there are big differences between locations. Also note that Windy can get it wrong. I grew…

When you say Windy can get it wrong, isn't it really the underlying forecast models that are wrong?

It's unclear to me if Windy is doing much more than creating a great presentation of existing data. Their website does list an open ML role, though..

I wonder how much rolling your own weather forecast is tantamount to rolling your own crypto??

The wind animation doesn't work at all for me in Firefox (on Linux, version 91). I see a few large animation "sheets" where the wind is moving in the same direction, depending on where on the map I look. Works in Chromium. Anyone else have this problem?

By default, Windy uses the ECMWF weather model. You can also change it to GFS or ICON, which many american forecast websites use.

ECMWF, GFS and ICON are made by national/international forecasting agencies. IBM also has its own proprietary weather forecasting service, notably used by The Weather Channel. Other apps mostly use one of these models or aggregate predictions from different services (e.g. AccuWeather claims to aggregate many different models, including those from national agencies around the world)

Windy is fantastic. But, I'm curious if there are any apps or weather models that give probability distributions? Telling me that it is going to blow 10 mph is useful, but telling me, for example, that there is a 60% chance that there will be a 10 mph wind and a 40% chance that the wind will blow at 15 mph seems more in line with how I would naively assume weather forecasting works. Right now, the ECMWF [0] model in…

Perhaps something like this https://www.meteoblue.com/en/weather/forecast/multimodelense.... If you check the regular forecasts it also has a predictability figure.

Another option is the point forecast from weather.gov. For example, here's the forecast for Eastsound: https://forecast.weather.gov/MapClick.php?lat=48.6968&lon=-1...

Weird. I'm using Firefox 91.0.2 on Ubuntu 20.04 and it works fine. Maybe try opening it in a new empty profile and see if it works?
