From Greykite.surf:

“The Levante and Poniente are the dominant winds in Tarifa. The Levante can be extremely strong in Tarifa, usually around 30 knots, but sometimes it blows for days at a time at 50 knots or more. It is an easterly wind that originates in North Africa and blows across the Mediterranean and out into the Atlantic ocean through the Strait of Gibraltar.

The Poniente is the Westerly wind blowing in from the Atlantic Ocean. It tends to be less strong than the Levante, generally about 20 knots or so, but is usually much smoother and less gusty. The Levante and Poniente both blow more strongly in Tarifa than elsewhere because of the Venturi effect created by the Strait of Gibraltar.”
