The wave forecasts are now based on the higher resolution 0.5 degree (approx
50km) NWW3 Global Model and so the accuracy and especially timing of swells
should be much better. We will introduce many more significant improvements over the
coming weeks and months, starting with exclusive 10 day forecasts developed in-house. Best wishes. The surf-forecast team.
