Traveller notes on Fortaleza in December

Other months in Fortaleza

Forum posters describe February in Fortaleza itself as offering fabulous weather with warm, pleasant evenings for a walk, and rain that, while a genuine part of the February-through-June stretch, is typically brief enough not to disrupt more than part of a single day. Posters note Fortaleza's average temperature holds around 27C essentially year-round, living up to its cidade-sol (Sun City) nickname, with Carnival season in February or March a particular highlight. Posters do flag that nearby coastal spots like Jericoacoara and Canoa Quebrada are just entering their own rainy season by February, though conditions there can still be good since it's early in that transition. Posters generally rate February as warm and mostly sunny for Fortaleza itself, with rain a real but usually short-lived, manageable factor.

Forum posters call August one of Fortaleza's best months - part of the roughly August-through-March dry stretch with hot, sunny, almost rain-free conditions the norm. The Ceara coast (Fortaleza and nearby Jericoacoara both included) is well known among posters specifically for strong, near-constant wind this time of year, which makes the region a genuine hub for windsurfing and kitesurfing lessons - a double-edged feature that keeps beach days breezy and comfortable in the heat but can also affect swimming conditions and beach-umbrella setups. Posters consistently rate August as a safe, reliable choice for sun-seekers precisely because the dry season removes the rain risk that complicates travel in Brazil's wetter regions at the same time of year.
