GoWindow is the boating and fishing weather app that gives you one clear answer: GO or NO-GO. Set your personal comfort thresholds for wave height, wave period, wind, gusts, rain chance, temperature, and UV. GoWindow monitors marine and weather conditions across all your saved locations and evaluates them against YOUR limits — not someone else's idea of a nice day. One status tells you everything. INSTANT GO/NO-GO STATUS Your dashboard opens on a live map of your spot with a clear GO / CAUTION / NO-GO verdict, your best departure window ("Friday 5 AM – 9 PM"), and quick cards for waves, wind, rain, and temperature. LIVE MARINE MAPS — NEW A full Maps tab with animated rain radar (recent past through the forecast ahead, with a scrubbable timeline), plus live layers for water temperature, wave height, wind, currents, and air temperature that follow the coastline. Tap anywhere on a layer to read the exact value. Toggle NOAA tide stations and offshore buoys, and tap any pin for the next tide or a live buoy report. GOWINDOW PREDICTION — NEW A 12-hour offshore outlook that weighs seas, wind, wave period and direction, recent storms, tides and the moon, nearby buoy readings, and how well the forecast models agree — then explains its reasoning, factor by factor. 8-DAY MARINE FORECAST Day-by-day breakdown with color-coded threshold indicators, wave period, storm badges, tide times, and morning/afternoon/evening detail. SET-AND-FORGET ALERTS Get told the evening before a GO day, the moment conditions turn favorable, and each morning with a daily briefing — built so they keep arriving even when you haven't opened the app in days. Storm alerts warn you when lightning is headed for your spot. CUSTOM THRESHOLDS Your rules: wave height, wave period, wind, gusts, rain, min/max temperature, and UV — each one yours to set or ignore. What works for a kayaker is different from an offshore fisherman. MULTI-LOCATION MONITORING Track marinas, coastlines, offshore waypoints, and fishing spots. Search, enter GPS coordinates, or drop a pin. GoWindow surfaces the best conditions across all your spots. MULTI-DAY TRIP PLANNING Find consecutive GO-day windows for extended trips — configure a 2–5 day window and GoWindow finds the first stretch that clears your limits. HOME SCREEN WIDGETS Widgets show your status and next good window — and they refresh themselves, so the answer on your home screen stays current. PROFESSIONAL-GRADE DATA Marine data from Open-Meteo. Atmospheric data from Apple WeatherKit. Radar by RainViewer. Tides and buoys from NOAA. Combined into one clear evaluation. PRIVACY FIRST No accounts. No trackers. No analytics. Your locations stay on your device; coordinates are sent only to weather providers to retrieve forecasts. Whether you're a weekend angler, offshore fisherman, kayaker, or sailor — GoWindow takes the guesswork out so you spend less time checking forecasts and more time on the water.
