Wind forecasts for kitesurf, windsurf, and surf — maps, session logging, and an assistant in plain language. Ride more, guess less.
Wyndow is the weather and planning companion for kitesurfers, windsurfers, and surfers who want forecasts that match how they actually ride—not generic beach weather. Every plan includes Wyndow Fusion, our ML-enhanced hyperlocal layer (~100 m), blended with ICON, ECMWF, GFS, and regional national models where they matter for your spot.
SEE THE WIND AND THE OCEAN, NOT JUST NUMBERS
Browse spots on a map or list, open a spot, and get forecasts tuned for going on the water: wind speed and direction, gusts, waves, tides when available, and more. Narrowcast keeps today and tomorrow in focus; Explorer and Navigator add longer multi-day Forecast views so you can line up sessions with the right conditions—whether you’re on a kite, a windsurf rig, or a board. Set condition-based alerts so you hear when it’s worth checking the forecast.
YOUR SPOTS, YOUR SESSIONS
Keep track of where you rode and how it felt. Log sessions on iPhone or Apple Watch with notes and ratings, then share a session card when you want to show friends what you scored. Learn what works for you over time.
APPLE WATCH COMPANION (EVERY PLAN)
Check wind and waves from your wrist, sync saved spots to the watch (limits vary by plan), and use complications for a quick read between sets. On GPS + cellular watches, complications can refresh over Wi‑Fi or cellular when signed in—or Wi‑Fi only in watch Settings. Session recordings sync to iPhone for review, then upload to your account. One account across iPhone, watch, and web—no extra subscription tier for watch access.
IPHONE HOME SCREEN WIDGETS
Add Wyndow widgets to your Home Screen or Lock Screen for wind, tide, swell, and forecast at a glance—no need to open the app. Widgets sync when you use the app and show your favorite spot’s latest conditions. Long-press the app icon for quick actions: start a session, open favorites, or jump to planned and past sessions.
ASK IN PLAIN LANGUAGE
Use Kairos, the built-in assistant, to ask about conditions, spots, or planning—like chatting with someone who knows wind and wave sports. Voice input is optional when you’d rather talk than type (Explorer & Navigator).
STAY IN SYNC ACROSS DEVICES
Use Wyndow on iPhone, Apple Watch, and the web app when you want a bigger screen; your account ties forecasts, spots, alerts, and sessions together.
BUILT FOR RIDERS
Whether you kite, windsurf, surf, foil, or chase nuking wind, Wyndow helps you spend less time guessing and more time on the water.
