Swellwire — Surf & Weather, Reimagined

Swellwire is the surf and weather app for people who want to actually understand the ocean. Beautiful, fast, and built on the same NOAA data the pros rely on — wrapped in an interactive 3D globe you'll want to keep open.

Plan every session with confidence

16-day extended swell forecasts powered by NOAA's GFS-Wave global model
Live buoy observations from NOAA NDBC, refreshed every 30 minutes
Wave height, period, direction, swell components, wind, and weather — all in one view
Save your favorite spots and check conditions in a tap
Explore the planet, not just the lineup
Swellwire isn't just a surf app — it's a window onto the entire atmosphere and ocean. Spin a gorgeous interactive globe and switch between modes:

Ocean — currents, wave height, sea surface temperature, SST anomaly, salinity
Air — wind, temperature, humidity, pressure, precipitation, cloud cover, CAPE
Chem — CO, CO₂, SO₂, NO₂
Particulates — dust, PM1, PM2.5, PM10, organic matter, sulfate
Space — aurora forecasts
Bio — coral bleaching alerts
Visualize it your way

Animated wind vectors and overlay playback
Multiple map projections: 3D globe, Mercator, equirectangular, stereographic, and more
Pressure-level slices from the surface up to 10 hPa
Graticule, coordinates, and clean color scales tuned for readability
Built on real data, not guesses

NOAA NDBC buoy network
NOAA NWS forecasts
NOAA GFS-Wave global GRIB2
No middlemen, no marketing-grade "smoothing"
Whether you're chasing the next swell, tracking a hurricane, watching wildfire smoke, or just curious what the planet is doing right now — Swellwire makes it gorgeous, accurate, and instant.
