These colors depict the height of waves, more exactly the significant height. The scale in the low right corner of your screen shows the height of the waves according to the colors

@mmakai
In addition, concerning the colors, the Cloud layer is in fact a mix of cloud + rain.
Rain is shown by the small dots which correspond to the amount of rain during 3 hours according to the color scale in right low corner of your screen. This scale is in mm but you can choose inches.
In the weather picker, 21.4mm is rain amount and 100% the cloud cover.

Then the only possibility to get the cloud cover scale is to go to Settings -> Customize color scale -> Select overlay -> Clouds

Note there is a mistake. The units for clouds are not mm but % as shown in the weather picker.

Hope it helps.

Your long speech teaches me nothing. That’s exactly what I've explained so far. Next time give that kind of explanation to the person asking a question not to me.

@stoa
In Settings select
Show lat, lon grid
and
Weather picker contains lat, lon

@vsinceac
Never mind you will not convince me.

And for your information grass temperature is not a joke.

@FransBetsy said in 10cm temperature:

Re: Ground temperature
I repeat my suggestion/request for ground temperature at 10cm aka grass temperature.

https://www.weatheronline.co.uk/reports/wxfacts/Grass-Minimum-Temperature.htm
Weather On Line has probably developed their own « cocking recipe » using the factors I explained in my first post. Windy visualizes raw data from weather models, only. The do not develop their own algorithm, as far as I know.

@vsinceac
The parameter that you mention is the soil temperature between 0 and 10cm depth. So nothing to do with the air temperature above the ground surface or grass temperature.

@JPMBecker
Yes that’s not possible

@vsinceac
Yes Mate, and what is the accuracy of a 22km resolution for grass temperature?

@Gkikas-LGPZ
I don't think that an article is automatically published once you write it and put it in the Article section. Someone in the Windy team does the job to publish it. It's what I learned from @pavelneuman.
Or you can do it by yourself

Personally I'm not familiar with the back office job so I leave specialists to do it.

@FransBetsy
Hi,
Windy visualizes data from weather models and I am not sure that these models provide a temperature prediction at 10cm above ground surface. Then if you consider the resolution of the models that Windy shows in your region, a 10cm-temperature will not be very reliable when the resolution is about 10km and the risk of frost depends on topography and other local factors.

Windy gives you the possibility to make your own assessment for the risk of frost. This risk depends on:
Temperature: air temperature at 2m
Humidity: air with high content of water vapor prevents quick night cooling, because it reduces the infrared radiation from the ground.
Dew point: it is the temperature at which the dew forms. The lower this temperature is predicted, the higher is the cooling expected. If this temperature is negative, the risk of freezing will be really high.
Clouds: cloudiness reduces the infrared radiation from the ground and thus the risk of frost. Clear sky at night increases the risk of frost.
Cloud height: low clouds are more efficient to reduce to risk of frost than high clouds.
Wind: the wind blows the cold air near the soil, mix it with the layers above and decreases the risk of frost.

All these parameters are provided by Windy, as a layer and also in the Meteogram for a given location.
So you can try to make your own assessment using these parameters.
