The quiet coasts that February rewards
February is high season for weather almost everywhere on the Mexican coast — dry days, warm water, low rain risk — but not everywhere is full. The Oaxaca coast is the clearest example. Puerto Escondido's Zicatela is busy with surfers, yet Playa Carrizalillo and the Rinconada strip stay calmer, and the small towns of Mazunte and Zipolite, an hour or so further down the Carretera 200, run at a gentler pace. Rooms here are simple; expect fans more often than air conditioning in the cheapest band.
Further north, the Costa Alegre between Manzanillo and Puerto Vallarta — Barra de Navidad, San Patricio Melaque, Careyes — is where Mexican families holiday, and February sits between the Christmas rush and Semana Santa. Los Ayala and Lo de Marcos in Nayarit are similar. I would book San Patricio Melaque for a long, walkable beach and a working town, and skip Careyes unless the resort seclusion is the point. On the Caribbean side, Holbox and the southern end of Isla Mujeres are quieter than Cancún in the same week, though sargassum can appear on Caribbean beaches even in February — ask before you book a beachfront room.
Cities to base in before or after the beach
February is one of the best months for Mexico City: dry, cool at night, and short queues at the Museo Nacional de Antropología in Chapultepec. Base in Roma Norte or Condesa around Parque México, where you can walk to breakfast and take the Metro from Insurgentes. The historic centre around the Zócalo and Bellas Artes is fine for sightseeing but noisy at night — I would book Roma over the centro for a first visit, and use the Metrobús on Avenida Insurgentes rather than taxis at rush hour.
Oaxaca city is another strong February base, with the walkable centre between the zócalo and the Santo Domingo church, and day trips to Monte Albán twenty minutes by road. San Miguel de Allende and Guanajuato in the Bajío are cooler and drier than the coast, with the Guanajuato airport about thirty minutes from the city. These are hotel-heavy towns in high season, so reserve a room with parking if you are driving; street parking in central Guanajuato is genuinely difficult.
Prices, booking and what to skip
Expect February rates above January's but below Easter week's in most coastal destinations, with the sharpest jump in Carnaval towns during their parade dates. Beach towns with three- and four-star inventory — Sayulita, Puerto Escondido, Melaque — offer the best value in the middle band, while all-inclusive corridors around Cancún and Puerto Vallarta charge a premium for the same week. Booking two to three months out is reasonable for the coast; for Mazatlán during Carnaval, start earlier and be flexible on neighbourhood rather than on dates.
Skip the temptation to string together too many stops. Distances are long: Tulum to Holbox is roughly two and a half hours by road plus a ferry, and Puerto Escondido to Mazunte is about an hour on a winding road. Two bases in a week is comfortable; four is not. If your priority is warm water and easy flights, I would book Puerto Vallarta and use it for the Bahía de Banderas beaches; if it is culture, Mexico City plus a short hop to Oaxaca. Check cancellation terms before you pay, since February weather is usually reliable but not guaranteed.
