Significant wave height here is the total measured sea state at this mooring. It is not the height breaking at any beach; each beach page models that separately from its own exposure.

This is the recorded start of the most recent successful live poll across this station's products, not response completion or proof that every field refreshed.

One instrument's own reading of open water, selected independently of the water temperature station. The observation time is the oldest of the wave fields shown, so it can overstate a single field's age but never understate it. The fetch timestamp records the start of a successful poll of this field's provider and product, not response completion or the age of the reading.

All times are Pacific. An upstream issue time is shown only when recorded. A feed response time is not the provider's model initialization or publication time. Unlisted timestamps were not recorded or do not apply.

Station Observations — San FranciscoWhat this station measuresThese are instrument measurements at this station, which may be an offshore buoy or a fixed coastal platform. Significant wave height is not a beach-specific breaking height. Each beach page states its own modeled breaking height separately.NDBC 46026 · raw observations · past 168 h

San FranciscoWhat a wave model forecast isOpen-Meteo Marine runs a wave model over this station's location. Every point on these lanes is model output rather than an instrument reading, and the offshore heights shown are the open-water sea state, not the height breaking at a beach.46026 · 7-day swell forecast · Open-Meteo Marine
