GoWindow is the boating and fishing weather app that gives you one clear answer: GO or NO-GO.

Stop checking multiple forecast apps. Set your personal comfort thresholds for wave height, wind speed, gusts, rain chance, temperature, and UV index. GoWindow evaluates marine and weather conditions across your saved locations and tells you when conditions meet your standards.

GO / CAUTION / NO-GO STATUS
Your dashboard shows an animated status indicator that evaluates conditions at your best location. Quick-view cards display current waves, wind, rain, and temperature at a glance. Pull to refresh for the latest data.

TRACK ALL YOUR SPOTS
Monitor multiple marinas, coastlines, and fishing spots. Add locations by searching, entering GPS coordinates, or dropping a pin on the map. GoWindow automatically identifies the best conditions across all your saved locations.

8-DAY MARINE FORECAST
See a day-by-day forecast with color-coded threshold indicators. Expand each day for wind direction, gusts, UV index, and detailed conditions. Red highlights show where conditions exceed your limits.

SMART NOTIFICATIONS
Get alerted the moment conditions turn GO at any of your locations. Daily morning summaries include your status, best location, and key conditions. "Go Tuesday!" format makes trip planning simple.

CUSTOM THRESHOLDS
Your comfort, your rules. Set limits for up to 7 conditions: wave height, sustained wind, gusts, rain chance, temperature range, and UV index. Toggle each condition on or off. What works for a kayaker is different from an offshore fisherman.

MULTI-DAY TRIP PLANNING
Planning a multi-day offshore trip? GoWindow finds consecutive days where all conditions meet your thresholds. Configure a 2-5 day window for extended trip planning — built for offshore fishing, cruising, and sailing weekends.

OFFSHORE-CAPABLE LOCATIONS
Add custom offshore waypoints by GPS coordinates or map pin. GoWindow validates marine data availability and suggests the nearest coastal point with wave data if needed.

PROFESSIONAL DATA SOURCES
Marine forecast data from Open-Meteo combined with atmospheric weather data for a complete picture. Wave height, swell, wind, precipitation, UV, and more — all evaluated against your personal thresholds.

PRIVACY FIRST
