October is one of the capital's most agreeable months. Daytime highs around 25°C keep things warm and comfortable, the Atlantic light is soft and golden, and the summer crowds have gone. Full-day sightseeing across the Kasbah des Oudayas, the Hassan Tower, the Chellah and the medina is a pleasure, and the evenings — still mild for now — are perfect for the riverfront and dinner by the medina walls.
The autumn weather stays largely settled, though the first Atlantic fronts begin to arrive late in the month, so the odd shower is possible. The gardens of the Oudayas and the Andalusian quarter remain green and inviting, and the storks are still a presence on the Chellah ruins. With gentler crowds and prices than the spring and summer peaks, October is a relaxed, value-led window to take in Morocco's elegant capital.
It is also an easy month for a wider northern loop. Casablanca is a quick train ride down the coast, while the Roman ruins of Volubilis and the imperial gate-city of Meknes are rewarding day trips in the warm, settled autumn weather. For warm days, soft light and a calm, monument-rich city, October is a top choice for visiting Rabat.
