San Luis Potosí Weather & Climate Guide 2026

The weather calendar for San Luis Potosí: season by season, with the trade-offs each month brings.

San Luis Potosí is a landlocked state in north-central Mexico spanning two dramatically different worlds: a high, dry altiplano around its colonial capital and the ghost town of Real de Catorce in the west, and the lush, waterfall-filled Huasteca Potosina rainforest in the east. The capital, San Luis Potosí de Gonzalez, is a former silver-mining boomtown whose historic center forms part of the UNESCO World Heritage Camino Real de Tierra Adentro route, while the Huasteca region draws travelers to turquoise rivers, the surrealist gardens of Las Pozas in Xilitla, and the sacred desert of Wirikuta.

San Luis Potosí state spans a semi-arid highland climate in the capital and central plateau (altitude around 1,860m/6,100ft) to a warm, humid subtropical climate in the Huasteca Potosina lowlands around Xilitla and Ciudad Valles. The capital has mild winters (highs around 21°C/70°F) and warm dry springs before summer, with a rainy season from June to October bringing most of the annual 585mm (23in) of rainfall, heaviest in July, August, and September. The Huasteca Potosina region is notably warmer and more humid year-round due to its lower elevation and dense subtropical forest.
