Now move the slider to see wind roses for more distant forecasts. 8 seconds (s) - normal surfing, 11 s - good, 14+ s - great (pure ground swell). The longer the period, the faster and more powerful the waves.
The color of each bar also shows the speed, so it could be not only this type of green, but other colors. The speed measured in units, depending on the part of the world you live: meters per second (m/s), miles per hour (mph), kilometers per hour (kph), knots (knt: 0.514 m/s, 1.15078 mph, 1.852 kph, 1 nautical mile per hour), beaufort (Beaufort wind force scale). Speed. The same green bar shows the speed of wind blowing from its direction for the choosen day and forecast steo (1 h or 3 h). In this case, from the southwest (SW) to the northeast (NE). It looks a bit different here:ĭirection. The green bar indicates the wind blowing FROM the definite cardinal direction, the direction is signed on the plot. So if you click on the forecast for a definite hour, on the wind rose you will see only wind speed and direction for this moment. If you want, change the forecast step: 1 hour or 3 hours. Open the spot and choose the date you want to get the forecast for: today, tomorrow or any day in the next 10 days. Reading a wind rose in the Windy.app is easy: The wind rose on the spot The wind rose you see in Windy.app is a traditional wind rose, like on the picture above, but in the app, it could be in two places: on the spot and in the Weather Archive.

For example, if you see only one bar on the plot, just one direction of the wind is possible. The length of each bar shows the frequency of this direction. On the wind rose diagram you see wind cardinal direction and wind speed (m/s, mph and so on). Photo: Wind rose for South Shore Meteo Station, Oregon, USA It looks very similar to the compass with cardinal directions: The traditional wind rose is a circle with colored bars sticking out its center. What are the types of wind roses and how to read a roses of wind? Wind roses are often used instead of wind tables to make information more vivid.

To be more particular, it shows the possibility of every direction of the wind and its strength. The wind rose is a vector diagram or a graphical chart, presented in a circular format, that illustrates wind direction and speed, measured at weather stations. It’s also necessary for activities wind may ruin: fishing, cycling, and others. Let's learn more about what is wind rose and how to read it. The wind rose is a diagram of the wind, or a picture of wind changes.
