Nijmegen Watersport Interface (NWI)
· v1.5
About
Stop guessing if the water is rowable and enjoyable!
Designed specifically for rowers and water sports enthusiasts in Nijmegen, this watch face provides real-time, hyper-local environmental data directly on your wrist. Unlike generic weather apps, this dashboard integrates data from Rijkswaterstaat and the high-resolution KNMI Harmonie Arome model to give you the most accurate local conditions available!
Visual Dashboard
The interface is designed for glanceability, set against a relaxed scenic background (with camels as they are clearly relaxing and stress reducing.):
* Wind Timeline (Knots): A color-coded timeline showing wind speed for Now, +1 Hour, +2 Hours, and Tomorrow Morning (09:00).
* Color Scale: Ranges from Purple (Calm/Ideal) to Red (Storm/Unsafe), similar to WindFinder.
* Water Level (Lobith): Displays the current water height in cm derived from the Lobith measuring station. Generally considered unrowable above 1265cm ! (due to dike/threshhold overflow and currents from the Waal.)
* Trend Indicator: Arrows (`^` or `v` or `=`) indicate if the water level is rising or falling significantly (±50cm) compared to tomorrow's forecast.
* Real-Time Weather:
* Precipitation: Expected rainfall for the next two hours (in mm).
* Temperature: Current air temperature (°C).
* Alerts: Automatic status indicators for **FOG** or **SUN**

# How it Works:
The watchface updates automatically hourly via your phone's internet connection. It pulls a lightweight data packet processed (hosted on a server in the Netherlands) specifically for the geography of the Spiewa.
