The seven days divide naturally into two different kinds of Atlantic holiday. Essaouira gives you an eighteenth-century fortified medina, working fishing port and streets that reward unhurried walking. Agadir has a longer resort waterfront, a large food and craft market, and access to the surf villages farther north. Three nights in each place leave a full cultural day and a flexible water day before one southbound road move; the last two full days can then be as active or restful as the weather allows. Start in Essaouira and leave from Agadir if your transport permits. A return to Marrakech needs its own journey time and fare. Winter is suited to outdoor walks and a room you enjoy spending time in; the Atlantic may still be cool. In summer, choose shade and a morning activity before the afternoon heat. Surfing depends on the actual beach and conditions, not the season printed on a brochure.
