Morocco's Atlantic coast strings Casablanca's Hassan II Mosque on the harbour, the medieval port of Essaouira's gull-haunted ramparts, Rabat's UNESCO Kasbah of the Udayas, and Asilah's painted-mural medina near Tangier.
Atlantic coast pleasant before summer heat, Essaouira Gnaoua World Music Festival in late June, and the medina walking comfortable across Rabat and Casablanca.
Casablanca and Rabat hit 30°C but Essaouira's wind keeps it 5°C cooler year-round, and the Atlantic surf at Imsouane and Taghazout running consistent swells.
Sea at warmest, Essaouira at peak for Atlantic seafood, and the Asilah Cultural Festival in mid-July aside, autumn brings the coast's best weather.
Mild Atlantic winter around 16°C, Essaouira surf at peak Atlantic swell, and Casablanca's Hassan II Mosque interior tours accessible without summer crowds.
