Windy is a very good weather app for outdoor activities, but it cannot be used as soon as you are offline.
So in any case you must rely on the advisories of local marine weather services via VHF, SSB HF or by GRIB files via satellite phone.
For 48h or 72h offline, I keep a screen video of the wind forecast for the next 5 days. But for long voyage there is no way to get weather prediction at sea from Windy.

RE: Colours on the pressure map
For a long time I have customized the colours of the Pressure layer so as to make it easier to identify the areas of high and low pressure, in red and blue with white in betwen. Recently Windy has introduced a new colour palette for Pressure similar to my settings but with a slight different hue. For me this new palette is much better than the old one.
New Windy settings:
The white can be replaced by a light grey if you want to see the wind animation clearly when pressure is near 1013 hPa.
With the old Windy colour palette the wind animation was not so visible with Lows shown in white, as seen from an old post:
RE: Wind Values?
You cannot add wind values to the wind vectors, but it is possible to customize the wind layer colors.
The solution is to choose a different color for each 5 mph range for instance. This is what has been done with the colors matching the Beaufort scale for the wind here:
Note that colors are not smoothed, not blended, and knowing your color choices you can identify the wind speed ranges e.g. the areas with a ...10-15 mph, 15-20 mph, 20-25 mph...wind, each range corresponding to a colour.
RE: Annoing map labels in poland or Czechoslovakia
These labels need probably to be updated in OSM.
By the way, Czechoslovakia is no longer existing too ! 😁
RE: Hashmarks in radar
Images like this one
mean radar data are a little old.
Images like that
means "no data"
RE: Conversion to PPM
SO2 data supplied by Copernicus are NOW corresponding to a column of this gas from ground to top of atmosphere and accordingly mg/m2 is the correct unit.
Please, the description of SO2 layer in the FAQ should be changed :
RE: What am I doing wrong. On the temperature layer, Windy.com flag says temperature back home is 91, but it is 82.
You already got several answers to the same question 2 years ago:
Have you tried all the models that Windy provides, ECMWF, GFS, NAM, METEOBLUE, and compared them?
Have you compared the temperature forecasts with local official weather stations?
For temperature, it seems that METEOBLUE (only available in Meteogram) matches fairly well a local Personal Weather Station (madis) close to your location :
Note that the Windy widget works only with ECMWF model and that METEOBLUE is not shown as a map neither in the weather picker (small flag), but only in Basic meteogram.
And as a conclusion the question is NOT "how accurate Windy is", because Windy does NOT make predictions, but just visualizes raw data from weather models run by major meteorological centers like ECMWF, NOAA,.... the right question would be "what is the best weather model for this location".
