*** After some flaky uptime we've switched to using the brilliant Forecast.io to power Windsock. If your sites don't update you'll need to delete them and then add them again for hourly forecasts to kick in. Sorry for this. Any questions just email us **

Essential kit for outdoor activities such as kitesurfing, windsurfing, paragliding, kite flying or just flying model planes. Have you ever flown a kite or model aeroplane? Packing the flight gear and driving down to the park only to find it's too windy to fly can be frustrating. Instead use this app to drop windsock markers down on a map and get the latest wind readings for a near-by location so you know if it's great weather for your activity.

Save your marker as a site and you can get the wind speed and direction up to 5 days in advance with 48 hour high-resolution wind readings every hour. On demand for almost anywhere in the world. If your device has a built-in compass, use "Relative Wind Directions" to quickly work out the wind direction and get wind speeds in kts, ft/s, mph, m/s and kph.
