In weather routing softwares, I know that in addition to their own library of polars there is the possibility to add / modify .text polar files. But where do you find polars database in such format available for any boat?

@Jungbl you forgot to mention that air pressure affects tides.

Thanks for adding this forecast to your model. I’m a glider pilot with over 1000 hours. SkySight is a great example of what competitive glider pilots are using now.

@CVBG Yes, you can subscribe via App Store, and you can use Premium across all your devices.

I've been a premium subscriber for a while, even when the benefits were marginal to me, and I like Windy a lot. But, watch your premium segmentation with care, ventusky.com is free and addresses a number of models without ads [it appears to be something of a side project?].

Once people are more alert about it, segmenting certain features into Premium may be a bit pushing on a string. For what it's worth, the availability of hourly forecasting data with HRRR/NBM is why I suggest it to people not invested enough to pay for Windy to use Ventusky.

So here's what keeps me paying for Windy without complaint:

Higher resolution ECMWF The denser presentation of forecast data across hours and days More obscure map layers, like soil moisture

Ventusky could fix #2, in many ways the mobile application and web site are a bit more polished than Windy, but perhaps some of the polish makes it difficult to make dense and functional presentation.

They have a number of layers, so I think they could fix #3 in all practical respects for widening use cases in time.

But with their side-project-ish (non) revenue, it seems unlikely they could approach #1, assuming high resolution ECMWF costs a decent amount of money.

While I don't mean to suggest that Windy should be looking to "compete" with Ventusky for market share or anything like that, the choice of what to put behind premium and advertise as reasons to buy premium exists in equilibrium with other things available, and I guess I'm affectionate enough about Windy that I wanted to give my impression of reasons why I feel satisfied in continuing to pay for Premium, as I have for some time. Consider it a bit of unsolicited user or market research.

This makes keeping track of progress during the day challenging. I'm crossing my fingers that the clock will reach the summit.

The display of satellite images by windy.com is very good, not only smooth, but also perfect in detail, which is a model for global meteorological departments to learn from. I would like to ask, what are the color schemes of the three displays (BLUE, VISIBLE, INFRA+) inside? Was it composited using "RGB"? Is there any relevant literature that can be referred to?

@przemo1986
Yes that's right, the previous INFRA layer has disappeared. Only INFRA+, now called IR in the mobile app, is shown with the colorised low temperatures of high cloud tops.
What does the old infra red layer without color really was bringing?
