        Here is a description of units in Meteogram

        Displayed temperature and dew point represents values 2m above the surface.

        framee 1.png

        Wind displays average wind speed 10m above the surface level.
        Wind gusts display values 10m above the surface in the last 3 hours.

        framee 2.png

        Shaded area symbolises temperature on the upper side and dew point on the lower side. Color matches with the values given, corresponds with the color scale.

        Temperature is close to the dew point = air is humid
        The difference between temp. and d.p. is bigger = air is dry
        Dew point and temp. are equal = relative humidity is 100% (fog)

        framee 4.png

        800h is short for 800hPa
        5km and 6400ft represent elevation both in meters and feet
        FL100 is short for Flight Level 10000ft
        framee 5.png

        Atmospheric pressure asl
        Some values of this curve are shown in the hPa line.

        framee 6.png

        Different colors of precipitations are explained in the Meteogram detail.

        Deep blue = rain
        Pink = convective rain
        Light blue = snow

        Grey clouds in Meteogram are calculated from relative humidity. It can be explained as a distribution of water in the atmosphere. The height in the Meteogram is in pressure levels. km/ft values are only rough estimation and they are AMSL.

        I don't understand what the grey areas mean. Can someone explain please

          The grey areas mean clouds.

            @idefix37 But the cloud base today scattered at 2700 and Broken at 3700 at Lydd airport. There was no rain except a,drizzle at 13.00 UTC. Yet the Meteogram showed a dark band right at the bottom with 0.2 blue vertical line at 13.00 UTC. The 'band' was almost black from late morning until late afternoon

              The Meteogram is providing a forecast, not an observation.
              Providing a screenshot would help.
              Have you tried several models ?
              Then this topic should clarify your question

                Hello, what is the color code for the temperature? Are the colors related to an average temperature for the chosen location?

                  @Thierry04 In terms for the color code for temps, the default one windy uses does not mean the average temp, but one scale used as a global average. We can change the temperature colors on the windy map. There's one scale I enjoy using and have used it for 5 years now. If you want to change your temperature colors, you could go on Windy, then press on the top right corner where it says "menu", then press settings, it's on the left of where it has 8 different things, then after that, scroll down to where it says "customize color scale", then after that, you should be able to change the scale to the desires you wish to have it on.

                      @galtsev Hi, we do not offer globe yet, so it is not possible to view it.

                      hello,could i wanna asked a question?in the meteogram,for example,does 9am means time from 6am to 9am or 9am to 12am?which one is the correct answer?Therefore, the precipitation at 9 am shows that 5mm is the total precipitation from 6 amto 9 am or the total precipitation from 9 amto 12 am?Or the precipitation of the hour at 9 am?

                      THANKS A LOT!

                        The 3hr precipitation shown at 9
                        is the accumulated preci. from 6 to 9.

                          ok,thanks!

                          If it's clear at 9am, does it mean that it's clear from 6am to 9am ? be grateful to you!

                            Hi! Can somebody tell me what this '8 cm' means in the rainfall forecast? I know there's no chance of 80 mm of rainfall today :b

                              8 cm of snow (equivalent to 8 mm rain).

                                I was using Windy but had some questions. This article cleared up all my doubts at once and will be very useful for my future mountain climbing. Thank you.
