Ancient pyramids, Caribbean beaches, mezcal-soaked Oaxaca nights — Mexico rewards you year-round, but the dry season (Nov–Apr) is when the Yucatán truly shines.
Mexico's calendar is dominated by two big variables: hurricane season on the Caribbean coast and the dry/wet split inland. Get the timing right and you get cenote visibility at 30 metres, empty Mayan ruins at sunrise, and Día de los Muertos in Oaxaca. Get it wrong and you risk a hurricane evacuation in Cancun.
The short answer: visit Mexico between mid-November and April. This is the dry season — minimal rain, warm sun, calm Caribbean seas (26–28°C), and zero hurricane risk. February scores 9.2/10 — our top month for Mexico — with the driest weather, best cenote visibility, and the lowest sargassum levels of the year.
If you want to fine-tune: December–April for Cancun, Tulum, and Riviera Maya beaches; March for whale watching in Baja California (and the Chichen Itza equinox); October 31–November 2 for Día de los Muertos in Oaxaca and Mexico City; May for shoulder-season value just before the rains; June–September for whale-shark snorkelling off Holbox (with hurricane-season caveats). The official hurricane season runs June 1 to November 30 with the highest risk in September–October — buy travel insurance if you go.
Data based on Cancun. Mexico City is cooler (altitude 2,240m). Oaxaca is warm and drier. Pacific coast (Puerto Vallarta, Huatulco) mirrors the Caribbean but with different hurricane risk.
Mexico's Caribbean coast shines November through April — minimal rain, turquoise seas, and brilliant sunshine. February scores 9.2/10: 29°C, barely 30mm of rain, and snorkeling visibility that exceeds 25m in the cenotes. This is also whale shark season (June–September off Holbox/Isla Mujeres) and whale watching season (December–March in Baja). Spring Break (March) brings US students flooding Cancun.
May is still excellent with minimal rain (85mm) and warm seas, but June marks the start of the hurricane season. Humidity increases, afternoon thunderstorms become daily, and the general atmosphere shifts. However, May is arguably the best value window — dry-season conditions at lower prices before the summer surge.
The Atlantic hurricane season officially runs June 1–November 30, with peak activity in September–October. The Yucatán Peninsula is periodically hit — Cancun has been devastated by major hurricanes. Travel insurance is essential, many resort rates drop 40–60%, and the gamble can pay off or ruin your trip. September is the most statistically risky month.
Mexico's calendar runs on dramatic religious festivals, archaeological alignments, wildlife migrations, and the rhythm of the hurricane and rainy seasons. Here's what's happening month-by-month.
