Sinaloa Weather Forecast

Sinaloa has a hot semi-arid to tropical climate along its extensive Pacific coastal plain, with Culiacan averaging 25°C annually and summer temperatures regularly exceeding 38°C. The coastal lowlands are the agricultural heartland of Mexico, producing much of the country's tomatoes, corn, and other crops.

The rainy season from July through October is driven by the North American Monsoon and occasional tropical cyclones from the Eastern Pacific. Annual rainfall ranges from 600mm in the northern coast to over 1,000mm in the southern Sierra Madre foothills. Hurricanes are a serious threat, with major storms like Hurricane Manuel in 2013 causing catastrophic flooding.

The Sierra Madre Occidental forms the state's eastern border and intercepts moisture-laden Pacific air, creating lush pine forests at higher elevations that contrast with the dry thorn scrub of the coastal plains. Mazatlan on the southern coast is one of Mexico's sunniest cities, with over 300 days of sunshine and sea breezes that moderate the intense summer heat.
