SFBOFS - San Francisco Bay Water Level Forecast Guidance

Effective on May 20, 2020 beginning at 18z Coordinated Universal Time (UTC), two major changes for NOS OFS datasets on THREDDS will be implemented. Please see the Service Change Notice for details


1. Retention period change - Only the most recent 31 days of OFS output files will be available on CO-OPS THREDDS.

2. File structure changes - To improve THREDDS performance related to file access and data aggregation

All model nowcast and forecast information is based on a hydrodynamic model and should be considered as computer-generated nowcast and forecast guidance.

This surface water level animation was created from the latest SFBOFS forecast guidance in the San Francisco. The forecast is for the next 48 hours of water levels as simulated by SFBOFS when is forced by forecast products from the National Weather Service's 4 km nested North American Model (NAM), tides from the Oregon State University Tidal Data Inversion, OTIS Regional Tide Solutions (2010) west coast tidal data WC2010 1/30°, and the Global operational Real-Time Ocean Forecast System (RTOFS).
