This is a separate product on api.met.no, not a part of Locationforecast. You can find the documentation for the Sunrise API here.
Currently the only services with full global coverage are Locationforecast, Frost (observations and climate) and TAF/METAR (airport weather conditions).
The Beaufort scale data has been removed to make the output language independent. It's trivial to translate from windspeed to Beaufort in your own language by using the standard table, e.g. from Wikipedia.
