Mexico's busiest periods include December to April, when visitors seek dry, sunny weather, and major holiday weeks such as Christmas, New Year and Easter's Semana Santa. Spring break can make Cancún and other Caribbean coast resorts particularly crowded in March. Domestic travel also increases around Mexican public holidays and Día de Muertos in early November. The quieter period is generally May to June and September to October, when heat, rain and hurricane risk reduce demand in some coastal destinations. Crowds vary by region and event calendar.

Mexico's hurricane season runs broadly from June to November, with the greatest tropical-cyclone risk often from August to October on the Pacific and Caribbean coasts. Storms can bring damaging winds, coastal flooding, heavy rain and landslides. The rainy season also increases flash-flood risk in some inland areas. Earthquakes are a year-round risk in parts of the country, particularly along the Pacific side. December to April is generally drier and less exposed to hurricanes, especially in beach destinations, though local hazards and official alerts should always guide decisions.

Mexico has varied climates, but many popular beach destinations are warm year-round. The dry season generally runs from November to April, offering sunnier conditions and lower humidity in many regions. May to October is hotter and wetter, with afternoon storms and higher humidity; hurricane risk affects coastal areas from June to November. Inland highland cities such as Mexico City are milder because of elevation, while northern deserts can be extremely hot in summer. December to March is often a comfortable period for beach holidays and sightseeing in much of the country.
