The buoys serves many audiences. For the National Weather Service, buoy data are used to forecast wave and weather conditions; observe current conditions, and change forecasts when observations are not the norm as expected. Boaters, anglers, paddlers and surfers use the data to make decisions about their personal safety, i.e. assess conditions before traveling out for the day. Charter fisherman use the data to make decisions about the safety of their customers and crew, and also which locations will be good for fishing depending on the current wind, wave and temperature conditions.
