Most weather apps show you a model's guess. JetCheck reads the live Seaway anemometer plus the Gold Coast Mk4 waverider buoy on every refresh, so you see what's actually happening on the water. Not what was modelled at 3am.
Wind, swell, period, gusts, tide, rain. All in one app, all rolled into one call: Go For it, OK-ish, or Give it a Miss. No spreadsheet thinking, no app-juggling at 6am.
Every threshold has been ground-truthed against actually being on the water. When the Broadwater goes from rippled to choppy. When a south wind's too much. When the ocean's unrideable. Not theoretical.
