March marks the tail end of Mexico’s peak dry season. The weather is at its best across the Caribbean, but spring break brings significant crowds and price spikes to the main resort areas. For those willing to look beyond Cancun, this remains one of the best weather months in the country.
Spring Break Pushes Cancún Hotel Prices 40–60 Percent Above January
Cancun, Playa del Carmen, and Tulum receive very large spring break groups from US colleges throughout March. The Hotel Zone in Cancun becomes noticeably rowdier during this period - pool parties, organised bar crawls, and beach events dominate the strip. Prices for hotels in the Hotel Zone can increase 40-60 percent above January rates during peak spring break weeks. Fixed-price all-inclusive resorts in Cancún help against the surge, and you can compare all-inclusive rates.
Alternatives for March that avoid spring break: Oaxaca, Mexico City, Merida, Guanajuato, and the Pacific coast (Puerto Vallarta, Los Cabos) see far less spring break impact. On the Caribbean side, Bacalar, Holbox, and Isla Mujeres maintain a calmer atmosphere. Tulum has shifted increasingly toward a design-hotel and wellness crowd that partly displaces the spring break demographic, but prices are still elevated.
Mérida Already at 35°C While Mexico City Stays Pleasant at Altitude
| City | Avg High °C | Avg Low °C | Rainfall mm | Humidity | Notes |
|---|---|---|---|---|---|
| Mexico City | 25 | 10 | ~10 | Low | Warm, some afternoon haze starting |
| Cancún | 30 | 22 | ~35 | Low | Dry, spring break crowds |
| Guadalajara | 29 | 13 | ~2 | Low | Dry season still holding |
| Oaxaca | 29 | 12 | ~10 | Low | Warm and mostly dry |
| Mérida | 35 | 20 | ~20 | Low | Getting hot, morning timing essential |
| Puerto Vallarta | 30 | 21 | ~5 | Low | Driest month of the year |
| San Cristóbal | 20 | 8 | ~20 | Low | Last cool month before rains arrive |
| La Paz (Baja) | 27 | 14 | ~5 | Low | End of whale season, snorkelling good |
Regional variation note: March is when altitude matters most for planning. Mérida (10 m, inland Yucatán) already hits 35°C and rising, while Mexico City (2,240 m) is warm but manageable at 22–25°C. Oaxaca (1,550 m) sits comfortably in the mid-to-upper 20s. Cancún is hot but sea breezes moderate the temperature that Mérida lacks. Puerto Vallarta records its driest month - approximately 5 mm - compared to around 35 mm in Cancún from coastal moisture.
Dry season continues across most regions. The Riviera Maya is warm at 28-31 C with very low rainfall and bright skies. The Pacific coast is similar. Mexico City and the central highlands are dry and warm at 22-26 C. Humidity starts building in some coastal areas toward the end of the month, signalling the approaching transition.
Mérida in the Yucatan interior reaches 35-38 C by late March - the heat becomes a factor for all-day sightseeing. Time outdoor activities for early morning and late afternoon.
CDMX Air Quality Inversion Season: When to Check IMECA Before Going Out
March and April typically see the worst air quality in Mexico City. Temperature inversions trap pollution over the Valley of Mexico, and the lack of rain means particulates accumulate. The IMECA air quality index (available online) monitors levels daily. Visibility from viewpoints like Chapultepec Castle or the Latin American Tower can be poor on bad days, and outdoor exercise is sometimes inadvisable when readings are high. If air quality is a concern, check forecasts before booking a March CDMX trip.
Whale Sharks Arrive off Holbox, Last Grey Whales Leave Baja Lagoons
Whale sharks begin arriving off Holbox and the northern tip of the Yucatan in small numbers from late March. The full aggregation peaks in July-August, but early arrivals make tours possible by the end of the month. Numbers are low enough that encounters feel intimate rather than crowded with tour boats. Our whale shark swimming guide explains how to choose an operator.
Grey whales are still present in Baja California lagoons (Scammon’s, San Ignacio) through early-to-mid March. The calves born in January are now more active and playful, making late-season encounters particularly rewarding. The season typically ends by mid-to-late March as the whales begin their northward migration to Alaska. Our whale watching in Baja California guide covers the last weeks of the season.
Monarch butterflies remain in the Michoacan sanctuaries through March, though numbers decline as the butterflies begin dispersing for their northward migration. Early March is still worthwhile; by late March the colonies have thinned considerably. See the monarch butterfly migration guide for late-season sanctuary visits.
Taxco Penitents and Oaxaca Alfombras: Semana Santa When Easter Falls in March
If Easter falls early, Semana Santa processions and events begin in late March (in 2027 Holy Week runs 21-28 March; see our full Semana Santa in Mexico guide for dates, booking windows and bus sell-outs). This is one of the most significant periods in the Mexican calendar - beaches fill with domestic tourists, flights spike in price, and colonial cities host elaborate religious processions.
Taxco has the most dramatic Semana Santa in Mexico, with hooded penitents carrying heavy crosses through cobblestone streets at night, accompanied by candlelit processions. Oaxaca features alfombras - intricate carpets made from coloured sand, flowers, and sawdust - laid on streets for the processions to walk over. San Cristobal de las Casas has processions that blend Catholic and indigenous Tzotzil Maya elements.
Book accommodation very early if travelling during Semana Santa - popular destinations sell out months in advance, and prices reach annual highs in resort areas.
Yucatán Cenotes at Their Clearest Before Spring Break Groups Arrive
March is an excellent month for cenotes. The dry season means groundwater is clear with minimal sediment, and the heat makes underground swimming pools particularly appealing. The most popular cenotes near Tulum (Gran Cenote, Cenote Azul, Cenote Calavera) are busiest during spring break - arrive before 9 am or visit lesser-known cenotes further from the tourist corridor for a better experience.
Oaxaca in March: Craft Villages, Hierve el Agua, and No Crowds
Best for dry-season Caribbean: go in the first two weeks before the peak spring break arrivals, or accept the crowds in exchange for reliably excellent weather.
Best alternative: Oaxaca in March is excellent - the craft villages surrounding the city (Teotitlan del Valle, San Bartolo Coyotepec) are accessible, Hierve el Agua is manageable before the heat intensifies, and the city itself is at its most comfortable temperature.

Plan Your Trip
The first two weeks suit highland Mexico - Mexico City, Guanajuato, San Miguel de Allende - but CDMX air quality can deteriorate mid-month. Spring break pushes Cancun and Playa del Carmen to peak pricing from mid-March: rooms that cost USD 80 in January can hit USD 250. When Semana Santa falls in late March, Taxco stages Mexico’s most dramatic Holy Week processions and is worth planning around. Cenotes across the Yucatán are crystal-clear before the rains, and manta ray aggregations begin off La Cruz de Huanacaxtle on the Pacific coast.
