Piauí

Piauí is a state in Brazil's Northeast Region, bounded by Maranhão, Ceará, Pernambuco, Bahia, and Tocantins. It features the shortest Atlantic coastline of any Brazilian coastal state at 66 kilometers, while its interior extends across semi-arid caatinga scrublands, sandstone plateaus, and river valleys along the Parnaíba basin. The capital, Teresina, sits 340 kilometers inland and is the only state capital in the Northeast located away from the ocean.

Travelers visit Piauí primarily for two distinct regions: the coastal north and the archaeological south. In the north, the Parnaíba Delta spreads across dozens of islands and mangrove channels before reaching Atlantic beaches like Barra Grande, a major kitesurfing hub. In the southern interior, Serra da Capivara National Park protects thousands of prehistoric rock paintings and excavation sites that have expanded scientific understanding of early human settlement in the Americas.

The climate across Piauí is hot year-round. The southern and central interior experiences dry heat with high daytime temperatures, while the northern coast receives steady trade winds. The regional economy and food traditions center on cashew production, cattle ranching, river fishing, and crab harvesting along the mangrove estuaries.

The most practical window to visit Piauí is during the dry season from June to September. During these months, rainfall is minimal, dirt access roads in national parks remain passable, and humidity is lower.

In Teresina and the central interior, daytime temperatures consistently reach 34°C to 39°C (93°F to 102°F). The hottest period, known locally as "B-R-O-Bró" (September through December), regularly records temperatures above 40°C (104°F) alongside intense electrical storms before the rains begin. The rainy season runs from January through May, peaking in March and April with heavy downpours.

On the coast (Parnaíba, Luís Correia, Barra Grande), temperatures stay between 28°C and 32°C (82°F and 90°F) throughout the year. Kitesurfers should plan trips between July and December, when trade winds blow consistently between 20 and 30 knots.
