Question 1 of 2

Based on the wave characteristics forecasted by WW111 model on the coasts of Casablanca, Safi and Agadir, where do you think that wave heights increase first?

Significant wave heights started increasing from the north and progressed south, going from Casablanca to Safi 6 hours later and Agadir 6 hours after that.

Please make a selection.

Question 2 of 2

Focusing on the wave peak period, do you think these values are unusual?

On the Atlantic side, periods of about 12 to 14 s are typical. Contrast this with first case when periods reached 20 s.
