The Riviera Maya and Caribbean coast are at their finest December through April — the dry season brings sunny weather, calm turquoise seas, and white sand beaches at their most photogenic. Playa del Carmen and Tulum are excellent November through March before spring break crowds arrive. Cancún fills with spring breakers mid-March through April. Los Cabos and Cabo San Lucas on the Baja Peninsula are excellent October–April. Avoid the Caribbean coast September–October (peak hurricane risk).

The Baja Peninsula offers one of the world's most extraordinary wildlife experiences: gray whales give birth in protected lagoons December through March, and whale watchers can get within touching distance in guided pangas. Laguna San Ignacio and Scammon's Lagoon (near Guerrero Negro) are the prime gray whale sites. Humpback whales are best seen off the Pacific Coast near Los Cabos December through February. Blue whales feed off the Baja Peninsula February through March — some of the largest creatures on earth visible from shore. Whale watching season ends by late March as most whales begin their migration north.

Whale shark season runs July to September near Isla Mujeres and Holbox on the Yucatán Peninsula — the world's largest fish congregates here in extraordinary numbers. Snorkelling with whale sharks is one of Mexico's most unique experiences and is strictly regulated. This timing coincides with Mexico's rainy season on the coast, but whale shark tours operate in the mornings before afternoon storms. Book with licensed operators months ahead.

The monarch butterfly migration to Michoacán's sanctuaries (El Rosario, Cerro Pelón) is one of the natural world's great spectacles — hundreds of millions of monarch butterflies overwinter in the oyamel fir forests of central Mexico.

Book tours and accommodation in Morelia or Angangueo well ahead for January and February peak.

Mexico City is a year-round destination but March through May offers the best combination of pleasant temperatures (18–25°C), sunny mornings, and manageable crowds. Exploring Mexico City's world-class museums (Anthropology, Frida Kahlo, Palacio de Bellas Artes), the Teotihuacán pyramids, and the archaeological sites of the historic centre is most comfortable before June's rainy season begins. Other inland cities — Oaxaca, San Cristóbal, Guanajuato — follow similar patterns. October–November is an excellent second window, with Día de los Muertos adding cultural depth.

The Day of the Dead (Día de los Muertos) on November 1–2 is Mexico's most distinctive cultural celebration — cemeteries filled with marigolds, elaborate altars, parades, and family gatherings to honor the dead. Oaxaca has the most traditional celebrations; Mexico City hosts the most spectacular parade (inspired by the James Bond film). Mixquic, near Mexico City, has the most moving cemetery vigil. Book accommodation 2–3 months ahead. Late October to early November is ideal — prices are still shoulder season before December peak.

The Pacific Coast surf spots around Puerto Escondido peak May through October when southern swells arrive — May offers early surf season with fewer crowds before the rainy season is fully established. Jungle ruins like Palenque and Bonampak in southern Mexico are best visited November through March when the heat and humidity are more manageable. Canyon country — the Copper Canyon in northern Mexico (Chihuahua) is at its finest October through April with moderate temperatures.
