Marine Conditions (Open-Meteo)
Wave and current data for 10 ocean monitoring points worldwide — from the North Atlantic to the Southern Ocean:
- Wave Height — Significant wave height in meters
- Wave Period — Time between wave crests in seconds
- Wave Direction — Compass bearing of dominant swell
- Ocean Current Velocity — Surface current speed in m/s
- Ocean Current Direction — Current flow bearing
Tidal Water Levels (NOAA)
Real-time water levels from 10 NOAA tide stations along US coasts, updated every 6 minutes:
- The Battery, New York
- San Francisco, California
- Virginia Key, Florida
- Seattle, Washington
- Honolulu, Hawaii
- And 5 more coastal stations
Water levels are measured relative to Mean Lower Low Water (MLLW) in meters.
Sea level monitoring is critical for understanding long-term coastal change. Even small increases in baseline water levels dramatically amplify storm surge impacts.
River Discharge (Open-Meteo / GloFAS)
Daily river discharge for 10 major world rivers using the Global Flood Awareness System at 5km resolution:
- Mississippi, Amazon, Ganges, Danube, Rhine, Mekong, Nile, Yangtze, Columbia, Thames
Discharge measured in m³/s (cubic meters per second). Historical data available from 1984 with 7-month forecasts.
