micro.windguru.cz, the ultra lite version of Windguru.

The "micro" site was mainly made for offshore sailors who can only access internet using very bandwidth limited satellite or radio connections. Forecasts here are as small as possible, text only. You can view forecasts for any spot registered on Windguru or for any latitude / longitude you choose (PRO users only).


WRF 9 km resolution! forecasts for East Asia. (PRO users only)

Map of the covered area


NOAA/NCEP made a major GFS model upgrade. GFS forecasts now cover all globe with 27 km horizontal resolution. We also extended the forecast horizont to 10 days.

This is a big upgrade that affect not only windguru, but all the sites that rely on GFS (most of weather sites on the internet ;-), if you were used to make decisions based on GFS you should reconsider the way how you interpret the forecasts for your spot now, it may take a while to get used to the new forecasts.

Hope this is a good step for better forecasts all around the world!


Prices for Windguru PRO are now in EUR, you can also choose to pay in USD or CZK (price will recalculate according to latest official exchange rate). The shortest subscription is now 1 month.


By the end of July NOAA changed the output of their NWW3 models, since then many people complained about exaggerated wave forecasts of the coarse (1.25 x 1.0 degree resolution) data which we had inside GFS forecast. To eliminate this problem NWW3 50 km is now the default that displays inside GFS forecasts, this dataset seems to be more accurate. (Registered users can configure their preferences in settings.)


Quick spot select. Now we have a more comfortable spot selection tool. This little input field in the main spot menu and other places throughout the website is made to pick a spot as fast as possible. Bye bye long and complicated menus...

quickspot favourites
quick spot search box, it will immediately suggest 3 groups of spots that you would select most probably (if you have some of them):

1. Last 5 used spots (sorted by last use, yellow)

2. Your favourite spots (icon with a star)

3. Your custom spots (green)

You can use [up] and [down] arrow keys to select spot and confirm with [enter] key, or pick s spot by mouse. First item is always pre-selected - just hit [enter] to confirm.

As you start typing the spots get filtered to shorten the list.

quickspot suggest

Once you enter 3 or more characters it will search all the spots available on windguru and update the list accordingly.

Different kind of spots are marked by different colors and little windguru icons for easier navigation. If found, spots are sorted by importance and then alphabetically. Your favourite and custom spots come first, followed by "official" windguru spots (blue icons) and then custom spots entered by other users (grey icons).

We keep the older spot menu and favorite menus of course, but this new quick spot tool is now the default.

Hope you like it! :)


NWW3 50 km resolution wave model forecasts Especially surfers might be interested in this new addon... As you might already know the wave forecasts on windguru are powered by NWW3 model from NOAA and we only used their data with 1 latitude x 1.25 longitude degree resolution. Maybe you still remember... long time ago we tried to switch to the higher (0.5 x 0.5 degree) resolution model from NOAA, but after several complaints about aaccuracy of the new forecasts we reverted back. But... advantage of the higher resolution NWW3 model is that it not only offers the basic parameters (wave height, direction and period) but also distinguish different components: primary swell, secondary swell and wind waves. The coarse resolution NWW3 data do not have this.

Now we have both. By default we show the new 50 km NWW3 model as a separate table under the GFS forecast and the GFS forecast still includes the older NWW3 100 km resolution data, same as before. If you have other preference simply go to settings -> preferences where you can configure how to display waves (registered users only). You can choose which data to include inside GFS forecasts and which wave models to display as separate tables.

If you have some custom spots and want to have wave forecasts for them, you should now visit the settings section to check their wave forecast configuration.

NWW3 50 km


Custom colors in forecasts. The default colors in the forecasts were selected very carefully and we believe this is the best for average windsurfer or kiter. In case you have other preference, you now have an option, feel free to edit colors anyhow according to your personal taste. See settings -> colors. (registered users only)

Android app on Google Play
WG android QR code


Official Windguru app for Android. It's quite simple and very simliar to our mobile site at touch.windguru.cz. The main purpose of this app is to get easily to your windguru forecast on your phone or tablet. It does not have many features (at least yet) but should do what we need the most: to view the forecast in the format we are all used to :-)

Main features:

WG android 1 WG android 2 WG android 3

The plan is to release official apps for all major platforms and all these apps should look and work same or at least very similiar.

Please note that some Windguru apps already exist for several platforms (Android, iPhone, Windows Mobile, Windows Phone) - see the Help section. These apps are made by external partners and still are and will be supported by Windguru as alternatives.


Some minor updates:


WRF 9 km resolution! forecasts for South Africa. (PRO users only)

Map of the covered area


A little update of the Email alerts. Alerts now support conditions for wind gusts, and waves (NWW3 model).


Wind and temperature profile plots. Now you can see what wind and temperature is forecasted in different altitudes. Mouse over the "2D" tab on the forecast to select the profile. Same as the graphs introduced recently, the plots are drawn by the browser, SVG graphics support is required (all browsers except Internet Explorer 8 or below).

WG wind profile WG temp profile


Graphical version of the forecast. Now you can also see the forecasts as graphs, simply click the graph icon on the second tab of any forecast table.

WG forecast graph

Since the beginning of this site, the core of Windguru was the forecast displayed as colorful table with a lot of numbers. I think it will stay like this in future too because despite one can consider it a bit oldschool, the table shows a lot of info with high detail on a small space and still looks clear and uncluttered. But why not to offer alternative display option? Forecast graph offers another view, more eye candy :-) and some people will prefer it.

If you like to have the graphical view as your default, you can set it using the "options tab" on the main page.

Important notice: Your browser must support SVG graphics in order to display the graphical forecast. All good browsers (Chrome, Firefox, Opera, Safari, IE 9) are OK, but if you have Internet Explorer 8 or older it will not work, please switch to better browser if this is your case.

The positive thing is that all the graphs are not plain images that require additional data download, instead they are drawn by your browser, so it is also bandwith friendly for those with slower connections.

Graph example

What you see below is the first version of the graphical forecast (probably not final, we expect to fine-tune it over time).

There are two main sections of the graph, the upper part is dedicated to the most important = wind, it scales depending on how much wind is predicted, if strong wind is forecasted it is bigger, if there is not much wind it becomes smaller.

The bottom part shows the "less important" parameters like temperature, clouds, precipitation, pressure and humidity - all drawn into one section to save space.The cloud cover display is a little special so it needs a little more explanation: low clouds are the dark grey area that is drawn from bottom of the graph, high clouds are light grey drawn from the top of this graph section and middle clouds (medium grey) are drawn from the center both up and downwards. If any of these fill all the area then it means 100% cloud cover for given cloud layer. Because all the cloud layers are semi-transparent if there is a lot of clouds in all layers the whole cloud graph turns almost black indicating a lot of clouds, the darker it is the more clouds are forecasted and you can still see how much each layer participate.

Right now the units for wind speed and temperature are taken from the classic table forecast, if you want to switch them temporarily, go back to the normal forecast, change units to what you prefer and then open the graph tab again, it will redraw with selected units.

WG forecast graph example

Future plans are to use the graphical display for visualizing temperature profile and wind in higher levels. We also plan to allow users to customize graph appearance because not only wind addicted people watch Windguru and they probably have other preferences.

If you have an opinion or idea about the new graphs feel free to send some feedback. Thanks!

Wind / wave direction now displayed with higher precision. This is a tiny update which you will hardly notice but can be useful... Till now windguru only displayed 16 different arrows for direction (22.5 degree precision), now it can display it exactly without this limit. Your browser must support SVG graphics to see the difference (all better browsers do support it - Chrome, Firefox, Opera, Safari... if you use Internet Explorer then you need the current version 9, older IE versions will not work)

HRW 4 km resolution model forecasts for United States! These high-resolution model forecasts come from NOAA/NWS (US weather service) and they are powered by WRF model similiar to HRW forecasts for Hawaii. NOAA names this as HRW (High Resolution Window) so we will use the same label. They are running 2 different domains, one covers east-central part of US and updates twice per day (we will label this as HRWe), and the other west-central part of US and updates once per day (HRWw). Both provide forecast for 48 hours with 1 hour step. It is free for all users

After several complaints about the upgrade to wave forecasts on 27th march we are reverting back to the previous lower resolution NWW3 dataset. Later we can add the higher resolution data again but only as optional for users who want to test it.


The wave forecasts are now powered by NWW3 dataset with 50 km resolution. Untill now we used lower resolution data (1 x 1.25 degree) which correspond to something over 100 km. This upgrade should make the wave forecasts a little better. If you have some custom spots with wave forecast enabled, please check them in your settings, especially if you entered alternative coordinates for waves.


Windguru on Android. The app can be downloaded and installed from Android Market. It's FREE


Wind chill is now available as optional parameter in the forecast tables (registered users can enable it in settings).

Now you can select spots from a google map. This new feature should help you especially when you are searching for a forecast in a specific area but you do not know what you should be looking for in the long spot menu. You can display the map by clicking the "show map" checkbox near the spot menu (see the picture below). The map will always load the spots which you see in the "select spot" menu.

For example: select Italy, the spot menu will fill with all spots in Italy and they will also load into the map and display. If you want to see all spots in Europe then select ALL in country menu. You can even display ALL spots available by selecting ALL continents and then ALL in countries, but remember this will load a lot of spots and will be slow... I would suggest to use the map with recommended browsers. Internet Explorer is NOT recommended because it is very slow compared to others.

If there are more spots too close to each other they are grouped in the map, click the group icon to zoom in and show more detail.
