      2m above the surface.

      By 2m from the surface, do you mean 2m from 0m elevation? Or do you mean 2m from the elevation of the set location? If the former, how can I find out the temperature at that elevation in the meteogram?

                    I read your explanation but it's not clear to me. What does the color code in the wind and wind gust area of Meteogram represent?

                    Thanks

                      @Claudio-Grego It´s the same color per windspeed as in the maps. ColorCode.png

                          I’ve made a comparison of wind / gusts color scale in the map and in the basic meteogram.
                          Not very similar !

                            @Korina Good day. I have a question related to meteogram. Currently, I am not a premium user of windy.com app therefore the updates of forecast is two times a day. Is time of forecast (from sunrise to sunset)in meteogram is "latest forecast" even I am not a premium user?

                              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.

                              framee 7.png

                              Q: What does this Grey Layer means?

                                        @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?
