Mexico spans deserts, high-altitude plateaus, jungle and two coastlines, so "the best time to visit Mexico" is not a question with one answer. The right month for Oaxaca is the wrong month for Cancún.
Here is the breakdown by region, plus the four calendar items that decide prices.
The quick version#
Best weather across most of the country: November to April, the dry season.
Best value: May to June and September to October, when prices drop and the weather is still usable in most regions.
Worst risk for the Caribbean coast: September and October, the peak of hurricane season.
Book far ahead for: Day of the Dead, Semana Santa, and Christmas through New Year.
The four dates that move prices#
Semana Santa, the week before Easter, is when Mexicans travel domestically. Beaches fill, prices rise, and coastal towns are at their busiest of the year. This catches foreign visitors out more than any other date.
Day of the Dead, 31 October to 2 November, is spectacular in Oaxaca and Mexico City and books out months in advance.
Christmas to early January is peak season nationwide.
Spring break, through March, transforms Cancún, Playa del Carmen and Los Cabos specifically. If that is not what you want, avoid those places that month.
By region#
Mexico City
Best: March to May, warm and dry before the rains.
Rainy: June to September, which in practice means sunny mornings and a heavy afternoon downpour, not washed-out days.
Worth knowing: the city sits at roughly 2,240 metres, so it is mild year-round and never truly hot. Evenings are cool in every season. Bring a layer.
Cancún, Tulum and the Riviera Maya
Best: December to April — dry, sunny, and the water at its clearest.
Avoid: September and October, the peak of Atlantic hurricane season, which officially runs June to November.
The sargassum problem. This is the thing most seasonal guides omit. Brown sargassum seaweed washes onto the Caribbean coast in large volumes, typically worst between roughly April and August, and it varies enormously year to year and beach to beach. It is the single most common cause of disappointment on this coast, and it is genuinely unpredictable more than a few weeks out.
Value window: May and June — decent weather, lower prices, before hurricane risk peaks, with sargassum as the gamble.
Oaxaca
Dry season: November to May.
Best: October and November, after the rains, with Day of the Dead as the reason most people go.
Guelaguetza, the enormous Indigenous cultural festival, runs in July and is worth planning a trip around if that is your interest.
Puerto Vallarta and the Pacific coast
Best: November to May, dry and reliably sunny.
Whale watching: roughly December to March, when humpbacks are in Banderas Bay.
Rainy: June to October, hot and humid, with dramatic evening storms and the best sunsets of the year.
Guadalajara and the Bajío
Best: March to June, warm and dry before the summer rains.
Guadalajara is at altitude too, so it avoids the coastal heat.
Baja California
Best: October to May.
Grey whale season in the Pacific lagoons runs roughly December to April and is one of the great wildlife experiences in the Americas.
Avoid: high summer in the desert interior, which is genuinely dangerous heat.
Michoacán and the monarch butterflies
The overwintering monarch colonies are open roughly November to March, peaking in the middle of that window. It is a specific trip, at altitude, in cold mornings, and it is unlike anything else in the country.
The shoulder-season case#
May to June and September to October give meaningful savings on flights and accommodation across most of Mexico. The trade-off is regional: it is a good deal in Mexico City, Oaxaca and Guadalajara, and a gamble on the Caribbean coast where it overlaps with both sargassum and hurricanes.
"Rainy season" in most of inland Mexico means a predictable afternoon downpour that clears. It is much less disruptive than the label suggests, and the countryside is green rather than brown.
The part no calendar can tell you#
Whether the seaweed is bad this week, whether the rains have started early, and whether the festival you are planning around is actually worth the crowd this year are all local, current questions.

Frequently Asked Questions
What is the best time to visit Mexico overall?
November to April, the dry season for most of the country. That is also high season and priced accordingly. May to June and September to October give meaningful savings with usable weather inland, but on the Caribbean coast they overlap with sargassum and hurricane risk respectively.When is hurricane season in Mexico?
The Atlantic season officially runs June to November and peaks in September and October, which is the window to avoid for Cancún, Tulum and the Riviera Maya. The Pacific coast has its own rainy season roughly June to October, which brings hot humid days, dramatic evening storms and the best sunsets of the year rather than washed-out weeks.What is sargassum and when is it worst?
Sargassum is brown seaweed that washes onto Mexico’s Caribbean coast in large volumes, typically worst between roughly April and August. It is the single most common cause of disappointment on that coast and it varies enormously year to year and even beach to beach, so it is genuinely unpredictable more than a few weeks ahead. Most seasonal guides omit it entirely.Which dates should I book far in advance for?
Semana Santa, the week before Easter, when Mexicans travel domestically and coastal towns are at their fullest — this catches foreign visitors out more than any other date. Day of the Dead, 31 October to 2 November, which books out months ahead in Oaxaca and Mexico City. Christmas through early January nationwide. And spring break in March, which transforms Cancún, Playa del Carmen and Los Cabos specifically.Does it rain all day in Mexico’s rainy season?
No, and the label misleads people. In Mexico City and most of the inland highlands, rainy season means sunny mornings and a heavy afternoon downpour that clears. The countryside is green rather than brown, and prices are lower. It is far less disruptive than it sounds.
