The coastal plain is a narrow strip of land that reaches along the length of the Mexico and lies between the ocean and the foothills of the Sierra Madre Occidental Range. This stretch of Mexico’s western coastline belongs to the states of Sonora (upper half) and Sinaloa (lower half), while the mountains of the Sierra Madre Occidental Range, running parallel to the shoreline, extend into the states of Chihuahua (above) and Durango (below).

Sinaloa has a warm climate on the coast side, moderate-warm in the valleys and lower mountainskirts, moderate-cold in small mountains and cold in the high ones. Its weather characteristics vary from subtropical, found on the plains, to cold in the nearby mountains. Temperatures range from 22°C to 43°C with rains during the summer.

Sonora has varied physiographic regions, ranging from mountains to coastal plains to desert. Extreme high temperatures, upwards of 50 °C or higher occur in summer in desert areas while winters, although short, are cool compared with most of Mexico. Most parts of Sonora are located in the desert; the state is thus extremely arid. Some cities are less hot in summer and with cold winters because there are at an altitude of 1,500 or more, while other cities are extremely hot in summer and mild to warm in winter because they are at an altitude of 208 m or less.
