Great web site, my favorite escape from work on the net!

Samuel L, Member

Man, WindAlert is a drug... You need it to keep your wits about you instead of looking at every tree branch or flag you see. Thanks again for the great service!

Chris, Member, San Bruno, CA

We sail out of Solomons MD on the Chesapeake bay- you guys are always the most accurate forecast. The visual models are a great tool, and usually right on. While others are checking NWS forecasts that only give a generalization, your app gives me much more accurate forecasting for my area. Thanks a bunch! Chris

  • Reports for 50,000+ Weather Stations

    We are your complete weather information source. Through research and government connections we have access to real-time data feeds from a multitude of mesonets around the world and we are adding more stations all the time. Know of a station not yet in our system? Let us know!

  • Model Forecasts for any spot on Earth

    iWindsurf places the forecast AND real-time observation on the same graph so you can see for yourself how accurate the forecast is. However, a lot of sensors aren't placed exactly where you windsurf so iWindsurf gives you the ability to instantly get a forecast for anywhere in the world by just clicking the map. Save that location to create your own "Nowcast spot" to always know what the forecast is for WHERE YOU WINDSURF, not miles away like most weather services.

  • Onsite Reports

    Anyone, anywhere can quickly and easily provide a report of conditions. This crowdsourced data feed provides ground truth for a user’s specific activity. Rating and filtering algorithms help maximize the accuracy of each report.

  • Organize and Share Weather Data through MyWeather

    iWindsurf makes it easy for you to quickly save favorite station lists, maps, graphs, forecast tables, etc... into your own wind "Profile". You can make your own custom Profile for each of the different geographical regions where you windsurf. Bookmark them for your own use, and share them with your friends.

  • Radar

    We offer High Resolution NEXRAD Level 3 radar on a dynamic map interface enabling you to zoom in and pinpoint where rain and severe weather events are happening or are about to happen. In addition, we allow you to overlay observational data on top of the radar so you can see how the rain event is effecting surface conditions. (North America Only)

  • Real Time Nowcast Observations anywhere on Earth

    A Nowcast observation (Nowcast spot) is created by an algorithm that interpolates nearby observations and weighs against high resolution forecast model data. The results are surprisingly accurate and produces a unique global product that effectively fills in the gaps between existing weather stations. This proprietary algorithm is constantly being tweaked for improved accuracy and can be activated by the "Nowcast" map product or by simply clicking on a map in any open space.

  • Exclusive WRAMS High Resolution Forecast Model

    iWindsurf offers our own WRAMS forecast model in addition to all of the publicly available forecast models. WRAMS is a professional forecast model being run and tweaked for greater accuracy by ingesting iWindsurf's unique weather stations' reports and dataset. Most other weather websites offer the same rehash of government models but iWindsurf's WRAMS forecast model is truly unique, enhanced, and accurate.
