February in Rabat is January with a touch more brightness. Daytime highs nudge toward 18°C, the showers ease a little, and the bright spells between Atlantic fronts lengthen. The capital stays calm and good value, with the Kasbah des Oudayas, the Hassan Tower and the Chellah ruins all enjoyable without crowds. Evenings remain cool, so keep a warm layer for after dark, but the bite of deep winter has begun to soften along the coast.
It is a fine month for the slow, cultural side of the city. Rabat is Morocco's administrative heart and wears its monuments with quiet elegance — the royal mausoleum esplanade, the gardens of the Oudayas, the modern-art museum and the long medina to the sea. The storks of the Chellah are starting to return to their nests on the Roman and Merinid ruins, an early sign that spring is on the way to the capital.
February rewards travellers who want Morocco's capital at its most peaceful, before the spring travel season arrives. Pair it with Casablanca and the imperial inland — Meknes and the Roman ruins of Volubilis — for a low-season cultural loop. The weather is changeable rather than reliable, but the mild maritime climate keeps sightseeing comfortable on most days.
