Wyndow Fusion hyperlocal forecasts for kite, wind & surf. Kairos AI on Explorer (your regions) & Navigator (worldwide). Widgets + Watch included. 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-EU, ECMWF, GFS, and regional national models where they matter for your spot. See the wind and the ocean, not just the 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), log sessions on the water, and use complications for a quick read between sets. The watch app works with your iPhone — one account, no extra subscription tier for watch access. 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 (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.
