The Forecast is based on the GFS model. Forecasts are available worldwide. The horizontal resolution is about 13 km. Forecasts are computed 4 times a day, at about 5h, 11h, 17h and 23h UTC. Predictions are available in time steps of 3 hours for up to 10 days into the future.

The Superforecast for Europe is based on the newest versions of regional weather prediction models. At the moment the Superforecast is available for Europe in a horizontal resolution of 7 kilometers in hourly timesteps. The forecasts are generated four times a day, at about 2h, 8h, 14h and 20h UTC. There is no time delay, all values are presented as they become available from our computers. The Superforecast for Northern America covers North America with a horizontal resolution of 5 kilometers in hourly timesteps. Forecasts are generated at about 3:30h, 9:30h, 16:30h and 22:30h UTC.
The Superforecast for Egypt uses a 7km resolution in hourly timesteps. The forecast are updated at about 3:30h, 9:30h, 15:30h and 21:30h UTC.
The Superforecast for South Africa uses a 5km resolution in hourly timesteps. The forecast are updated at about 3h, 9h, 15h and 21h UTC.
The Superforecast for the Canary Islands uses a 5km resolution in hourly timesteps. The forecast are updated at about 3:15h, 9:15h, 15:15h and 21:15h UTC.

We always want to present you the best forecasts. Unfortunately, the forecasts for some spots and some wind directions are not as good as we want them to be. There are local effects and thermal influences at these spots, which are very hard to predict. If you surf for many years at your local spot you may know these peculiarities. But we are already working on this problem.
It is also possible that the general weather situation is very unstable, so that all numerical weather prediction models have problems forecasting the development of the weather situation. The path of pressure systems (high / low pressure) is crucial for the wind conditions. The computation of this path can be wrong if there are unstable weather situations.
Further the forecast quality declines with longer forecast horizons (e.g. 3 days or longer). This is a general problem with weather prediction models.

Forecast and Superforecast are based on different physical models. These models may predict the weather dynamics in different ways which results in different wind forecasts. Different values are a sign for the stability of the general weather situation.

In the spot/location forecast and on the forecast maps the wind speed and direction is predicted for 10 meters above ground. Air temperature and relative humidity is predicted for 2 meters above ground and all the other parameters are predicted for ground level.

The arrows are aligned with the wind stream direction. Example: a northerly wind (e.g. a wind that is coming from the north, blowing to the south) is indicated with an arrow pointing downward.

Predicted wind directions use true north as the reference.

Because of the better horizontal resolution, a more advanced physical model and a more detailed terrain model the Superforecast should be preferred. In addition, all predicted values are available in hourly timesteps.
In general, you have to look for your local spot which forecast model works better for you. For some spots this will be the Superforecast, for others this may also be the Forecast.

The wind gusts are computed by our forecast models. The forecasted values correspond to the maximum wind gusts at the given time.

The air pressure is measured at the elevation of the weather station. The forecasted air pressure is calculated for the elevation of the location.

The arrows are aligned with the wind stream direction. Example: a northerly wind (e.g. a wind that is coming from the north, blowing to the south) is indicated with an arrow pointing downward.

In addition to our spot forecasts we also have forecast maps for both Forecast and Superforecast. There is also a animation for every forecast map. Forecast maps give you a better picture of the general weather situation. There you can clearly see whether you are in the middle of a big wind field or if your local spot is barely touched by the wind field.

This is the Windfinder Windpreview. This tool allows you to view the current wind forecast at a glance. The colors and bar heights correspond to the forecasted wind speed - this allows you to quickly see days with high or low wind speeds. Click on one of the days to see the detailed forecast for the selected day.

The colors indicate the wind speed. Here is the used wind speed scale (all values are given in Knots):

The wave forecasts are computed with the global wave forecast model WW3 run by the American Weather Service NOAA. The forecasted wave values only give an estimation about the expected waves. Local conditions at the beaches can modify these values.

The wave forecast for the Mediterranean and Baltic sea is a regional high-resolution WW3 model run by the Fleet Numerical Meteorology and Oceanography Center (FNMOC). The forecasted wave values only give an estimation about the expected waves. Local conditions at the beaches can modify these values.

We are always interested in your experiences with our forecasts for your local spot. If you have any feedback, suggestions or questions, don't hesitate to send a mail to info@windfinder.com

All date and time values are in local time of the weather station.

We do not archive raw forecast data, we only archive measurements from our weather stations. If you want to receive past weather data, have a look at our historical weather data request page.

If the weather data does not update please click on the "Reload" button of your browser. If that does not help press and hold the "shift" key on your keyboard and click on the "Reload" button of your browser. You can also try to clear the browser cache.

The blue line indicates the average wind speed, the red line indicates the wind gusts. Please note that wind gusts are not available for all weather station and/or on all measurements.

You can watch measurement data for up to seven days in the past. To access these just select your preferred date in the "Past data" menu on the right hand side over the report chart. If your requested date is older than seven days, have a look at our historical weather data request page.

The wind statistics are generated from wind speed measurements at our weather stations. These are based on real measurements, not only forecasts. We only use the measurements from the daytime hours to compute the statistics. The statistics are refreshed at the beginning of each month.

As the wind statistics are generated based on real wind speed measurements, the main factor in the wind statistics accuracy is the location and setup of the weather station itself. For example it may be placed in a wind shadow area for some directions which will affect the wind readings. If you want to report such a weather station or if you know another local weather station that gives better results, don't hesitate to contact us via email to info@windfinder.com.

The wind direction distribution shows the percentage with which the wind blows from certain directions.

Windfinder uses local and historical data and scientific algorithms to calculate tides. The effects on tides by air pressure or winds are not considered in the tides calculations.

Tide heights are given relative to the "datum" which in most cases is one of several benchmarks corresponding to low tides of varying extremeness. The preferred benchmark in the U.S. is Mean Lower Low Water (MLLW). The odds of the predicted tide getting below MLLW on any given day are about half. The preferred benchmark in the Netherlands is Mean Low Water Springs (MLWS). MLWS is lower than MLLW. The predicted tide will get below MLWS on average only about twice a month. The preferred benchmark in Germany is Lowest Astronomical Tide (LAT). LAT is the lowest tide predicted over a 19 year period. The predicted tide will not get below LAT in that 19 year period, and is unlikely to get below it by any significant amount ever. Some U.S. locations for which a MLLW benchmark was unavailable use an estimated value of MLLW that is derived from the predictions. These estimates tend to yield predictions that differ from National Ocean Service published tables by (0.1 to 0.2) ft.

We offer severe weather warnings in cooperation with Meteogroup and their Severe Weather Centers.

Severe Weather Centre warns by means of a multilevel warning system. It will issue warnings of gale/storm, heavy rain, heavy snow, freezing rain, and thunderstorms (with heavy rain, hail and gale-force wind gusts). Beyond that, Severe Weather Centre gives advices on glazed frost and icy roads, severe frost and heat.

Severe Weather Centre warns by means of a multilevel warning system: YELLOW is the weather watch level which is issued if the occurrence of a severe weather event is probable but there are uncertainties about duration, intensity and/or the course of this severe weather event. The warning levels ORANGE, RED and VIOLET are flash warnings. These warnings are issued if meteorologists are certain about the occurrence of a severe weather event. The warning levels are dependent on the intensity of the severe weather. They vary from area to area to account for the different topographic and climatologic conditions.

Flash warnings of the warning levels ORANGE, RED and VIOLET are issued if the occurrence of a severe weather event is certain. This is generally 6 to 12 hours before the occurrence of such an event. Depending on the type of severe weather or weather conditions weather watches and flash warnings may be issued more shortly. Weather watches (YELLOW) are issued up to 48 hours in advance as the occurrence of the event may not be certain or there may be greater changes in time or in the intensity and in the moving direction of the forthcoming severe weather. The Severe Weather Centre team of meteorologists strives to warn of imminent severe weather as early and reliably as possible.

You need a mast or pole to install the sensors and electricity and internet access to upload the data to the internet. Please make sure that the sensors of the weather station are installed in a location where the wind can blow freely so that you get accurate wind readings. We recommend that you use a mast or pole (at least 2 meters long) and attach it on top of a roof. I might be useful to make test measurements at the planned installation site to see if the wind readings from the weather station will be accurate.

You will find an image from the Ubiquiti Aircam at Marina Sonwik in Flensburg/Germany. There are sample video streams of the Aircam (1280x720 px) available as well as sample video with Full HD (1920x1080 px and 30 frames per second).

When the weather station is installed in the Northern hemisphere you need to make sure that the solar panel on the sensor suite is oriented towards the south (180°). If you are in the southern hemisphere you need to align the solar panel on the sensor suite northwards. In the latter case you need to log into the Meteobridge at http://magicip.meteobridge.com, go the tab "Select station" and enter the value 180 in the field "wind direction" and and click "Save".

If you don't have fixed line internet access you can buy a UMTS router, a SIM card and a cellphone network provider. The weather station and webcam are simply connected to the UMTS router the same way as you would connect them to a DSL router.

We recommend that you simply purchase the upload mini computer Meteobridge. The Meteobridge allows easy automatic weather upload to Windfinder. You don't need a PC anymore to upload your data to Windfinder. Before getting the Meteobridge check your weather station for compatibility.
If you don’t want to purchase a Meteobridge then please submit your weather station information to us. We will then send you instructions for uploading your data.

If you still do not see any data then open the battery compartment on the underside of the Vantage Vue sensor suite. Make sure that the battery is placed properly (with plus and minus pole) in the battery compartment. To verify power, wait 30 seconds then push and release the white transmitter ID push button next to the battery compartment. The green transmitter ID LED next to the battery compartment will illuminate when you press the push button. Note: Press the push button once and release it. Do not press it multiple times or hold it down.

Please go to our partner website webcams.travel and submit your webcam. The webcam image will appear a few days later on Windfinder.

As soon as your weather station is connected to Windfinder you can get free advertising on Windfinder. Please follow the instructions on our advertising FAQ page and send us a banner. We will publish the banner on the weather pages of your location on the Windfinder website.

As soon as your weather station (purchased at our partner Weerhuisje) is connected to electricity and your internet access the data will be uploaded automatically to Windfinder. After installation you should receive an e-mail from Windfinder with a short explanation how to embed the weather data into your site. If you have not received this e-mail please go to our Homepageweather configuration page and search for your weather station on the map. Once you have found your weather station click "Configure homepage widget" and follow the instructions.

Please log into your Meteobridge at http://magicip.meteobridge.com and go to the tab "Push Services". Follow the instructions on the Meteobridge website to configure your push service.

The maximum reach of the radio signal is 100 meters. If you need to cover a greater distance then you need to buy a weather station like the Vantage Vue with the console unit.. The console covers about 300 meters distance for the radio signal and you also get a display unit. With the display unit you can show/monitor the weather data on site. However the console is also more expensive.

Yes, you will need the Ubiquiti airGateway.

If you want to show the live data to the people at the installation site you will need the Davis console.
