RainVis turns detailed weather data into a visual forecast you can understand at a glance. Build your own forecast by choosing the details that matter most to you. Instead of jumping between separate hourly, daily, wind, rain, tide, and radar screens, RainVis lets you customize the forecast view around your plans. Track rain chance, accumulation, temperature, wind, gusts, humidity, pressure, dew point, cloud cover, tide height, tidal coefficient, and solunar timing in one visual forecast. Expand any day to inspect the hourly chart, compare multiple metrics together, and see when conditions line up. RainVis is especially useful for coastal fishing, boating, surfing, and outdoor planning, where the best window often depends on more than one number. Add tide and solunar details to your forecast to see tide movement, coefficient, moon timing, and major/minor activity periods alongside weather.
