Fortaleza Storm Days Per Month

Storms in Fortaleza by month

Fortaleza sits on Brazil’s northeast coast as the capital of Ceará, and its tropical semi-arid climate splits the year cleanly into two seasons. Most of the rain falls between Feb–May, when accumulated totals push past 500 mm. The driver is the Intertropical Convergence Zone (ITCZ) sliding southward over the region.

During the pre-season window Jan–Feb, scattered showers show up as the ITCZ creeps closer. The stretch from Jun–Jan is the dry season instead: sunny skies, low humidity, and the occasional coastal drizzle. Every December, FUNCEME (Ceará Foundation for Meteorology and Water Resources) puts out an official seasonal forecast built on Pacific and Atlantic SST anomalies.

Applications

It comes in handy when you’re planning a trip, booking a beach event at Praia do Futuro or Beira-Mar, making farming calls out in the Ceará sertão, or designing urban drainage. It also helps gauge flash-flood risk along Avenida Beira-Mar, where a strong convective storm can leave the street flooded (enxurrada) in half an hour.

FAQ

Which month rains the most in Fortaleza? The peak usually lands in March and April, when monthly averages sit around 300–350 mm. April on its own can account for a quarter of the whole year’s rain.

Is hurricane season a concern? Not really. The city is so close to the Equator (3.7°S) that the Coriolis force is too weak to get a tropical cyclone spinning, and Fortaleza has never logged a hurricane.

Where can I check official forecasts? FUNCEME (funceme.br) runs daily bulletins along with quarterly rainfall outlooks. For national radar and severe-weather alerts covering Ceará, check INMET.
