Aguascalientes is the kind of Mexican city that rewards curiosity. Perched on a high plateau in north-central Mexico, it's a walkable colonial capital known as the birthplace of La Catrina, the iconic skeleton figure created by local artist José Guadalupe Posada that has become synonymous with Día de los Muertos across the country. Beyond its artistic heritage, you'll find thermal baths dating back centuries, a cathedral anchoring a lively central plaza, wineries on the city's outskirts, and two of Mexico's most spirited annual festivals: the Feria Nacional de San Marcos in spring and the Festival de las Calaveras each fall.
The best time to visit Aguascalientes is late January through late December, with the sweet spot falling in spring (March through May) when dry skies, warm temperatures, and the legendary Feria Nacional de San Marcos collide. The fair typically runs from mid-April into early May, drawing millions of visitors for three weeks of parades, concerts, food stalls, and livestock exhibitions. Expect an energy surge during that window, so book accommodation early. A strong secondary pick is late October through early November, when the Festival de las Calaveras fills the streets with skull parades and candlelit altars. One brief dip to note: conditions can slip around early to mid-June, when the rainy season begins to pick up and humidity climbs. Outside of those considerations, Aguascalientes is remarkably agreeable nearly year-round.
Spring in Aguascalientes, Mexico
Spring is when Aguascalientes truly comes alive. March and April deliver virtually zero rain, and humidity sits at its lowest levels of the year, making it easy to spend entire days on foot exploring the historic center. Afternoons warm to highs of 85.2°F (29.6°C), ideal for wandering between the Posada Museum in the Barrio del Encino and the baroque extravagance of Templo de San Antonio, whose eclectic mix of Gothic, Neoclassical, and Russian-influenced domes is unlike anything else in Mexico.
The main event is the Feria Nacional de San Marcos, one of Mexico's largest and oldest fairs, with over 190 years of history. Typically running from mid-April into early May around the feast day of St. Mark, the fair draws millions of visitors for three weeks of parades, live concerts at the Foro de las Estrellas, livestock exhibitions, and craft markets centered on the Jardín de San Marcos and Isla San Marcos. Hotels fill to capacity, and some locals even rent out their homes to fairgoers, so early booking is essential.
Mornings can still be crisp, with lows dropping to 48.7°F (9.3°C), so bring a light jacket for dawn strolls through the plaza. Early to mid-May actually brings the year's peak heat, with highs reaching 89.7°F (32.1°C) and lows around 55°F (12.8°C), so if you're visiting during the tail end of fair season, carry water and seek shade during midday. Tourism is at its slowest outside the Feria weeks, and accommodation deals are easy to find in March. A light breeze picks up in April, the windiest stretch of the year, keeping the warm afternoons pleasant as you explore the Government Palace murals or sample local wines at one of the nearby vineyards.
Summer in Aguascalientes, Mexico
Summer marks the arrival of Aguascalientes' rainy season, with afternoon showers becoming a regular companion from June onward. Precipitation picks up to roughly 4 to 5 wet days across the season, and humidity climbs noticeably, reaching its highest levels by September. Still, mornings typically start clear and sunny, giving you time to visit the Museo Nacional de la Muerte, whose collection of funerary art spanning pre-Columbian to modern times ties directly into the city's deep relationship with La Catrina and Día de los Muertos iconography.
Highs average 83°F (28.3°C), with lows of 57.4°F (14.1°C) keeping evenings comfortable for outdoor dining around Plaza de la Patria. Once the rains settle in by July and August, the surrounding landscape transforms into lush green, and the city feels refreshed each afternoon after the storms pass.
This is the busiest tourism period, particularly in June and July when Mexican families travel for school holidays. Accommodation rates run higher than usual, and weekend crowds fill the plazas. For a quieter experience, target weekdays. Pack an umbrella and quick-dry layers, but don't let the rain deter you; storms rarely last more than an hour or two before the sun returns.
Fall in Aguascalientes, Mexico
Fall brings one of the best reasons to visit Aguascalientes: the Festival de las Calaveras, a multi-day celebration held in late October through early November that honors the legacy of local artist José Guadalupe Posada and the traditions of Día de los Muertos. The festival fills the streets with skull parades along Avenida Madero, elaborate ofrenda contests, live music from the Symphony Orchestra of Aguascalientes, and face-painted crowds channeling Posada's famous Catrina. It's one of Mexico's most authentic Day of the Dead experiences, and it draws far fewer international tourists than Oaxaca or Mexico City.
The weather cooperates beautifully. September still sees occasional showers, but by October and November, precipitation tapers off significantly. Highs settle to a pleasant 78.6°F (25.9°C), and mornings are refreshing at 49.4°F (9.7°C), perfect for exploring Tres Centurias Park, a former railway workshop complex converted into gardens and cultural spaces. Days shorten slightly, with sunset arriving before 6:30 PM by November, so plan your outdoor time accordingly.
Tourism remains steady, making fall the second-busiest period, though it never approaches the intensity of the Feria weeks. Mid-September also brings Mexico's Independence Day celebrations, with the grito ceremony in the central plaza and fireworks lighting up the night sky. Pack a light sweater for evenings and enjoy the Ojocaliente thermal baths when morning temperatures call for a warm soak.
Winter in Aguascalientes, Mexico
Winter in Aguascalientes is quiet and unhurried, a welcome contrast to the festival energy of spring and fall. Tourist numbers dip, especially in January and February, making it easier to linger inside the Government Palace and take in the sweeping murals that depict the city's history without competing for space. The Posada Museum and the surrounding Barrio del Encino feel especially intimate during this period, with locals going about their daily routines in the cobblestone streets.
Afternoons remain mild, with highs of 74.6°F (23.7°C), though mornings are the coldest of the year, dropping to 39.6°F (4.2°C). A warm layer is essential for early outings, but by midday you can comfortably shed it. Rain is rare, showing up only once in a while throughout the season, and the dry air keeps the sky clear for views of the surrounding plateau. It's excellent weather for a day trip to the nearby Sierra Fría mountains or the lakeside town of San José de Gracia, where boat tours run on the reservoir.
December sees the year's highest visitor numbers, driven by holiday travel and Christmas celebrations. If you're visiting over the holidays, book well in advance. January and February, by contrast, represent the quietest stretch of the year, with the best accommodation availability and the most relaxed atmosphere. Carry sunscreen even in winter; the high altitude means UV exposure stays strong year-round.
