Chiapas is Mexico's southernmost state, a highland-and-jungle frontier on the Guatemalan border where colonial San Cristóbal de las Casas sits at 2,200 metres above sea level, the Maya city of Palenque rises out of rainforest, and the Grijalva River cuts the thousand-metre walls of the Sumidero Canyon. It is the most indigenous state in the country: Tzotzil, Tzeltal, Ch'ol, Tojolabal and Zoque communities keep their languages, markets and ceremonies as living practice rather than performance. Waterfalls at Agua Azul, Misol-Ha and El Chiflón, the turquoise lakes of Montebello, the coffee fincas of the Soconusco and the empty Pacific beaches at Puerto Arista round out a state that rewards slow, careful travel.
Chiapas has no single climate: it is a state of five distinct zones that a single packing list cannot cover. San Cristóbal de las Casas and the Los Altos highlands sit at about 2,200 metres and run cool and pine-forested, with daytime highs around 20-22°C year-round and nights that fall to 4-8°C from November to February; a frost is not unheard of in the coldest weeks of January. Tuxtla Gutiérrez and the Central Depression sit at roughly 530 metres and are noticeably hotter, often 30-34°C by afternoon even in the dry season. Palenque and the northern jungle lowlands, at around 80 metres, are hot and humid essentially every day of the year, typically 28-34°C with heavy afternoon humidity, especially from April to October. The Soconusco coast around Tapachula and the Pacific beaches at Puerto Arista sit at low elevation with tropical heat and humidity intensified by onshore wind. Statewide, the rainy season runs roughly June to October, peaking in September, while November to April is the dry season across all zones, though 'dry' in the jungle still means occasional short showers. A single Chiapas itinerary that moves from San Cristóbal to Palenque genuinely crosses from fleece-and-blanket weather to shorts-and-humidity weather in a single day.
Best time to visit
Items:
- Period
- Late November to mid-February
- Rating
- Best
- Description
- The core of the dry season across every zone: clear skies over the Sumidero Canyon, firm dry trails at Palenque and Toniná, and the waterfalls at Agua Azul and Misol-Ha running at strong flow with their full turquoise colour after the rains have cleared the sediment. This window also captures the Fiesta Grande de Chiapa de Corzo (8-23 January) and the busiest, most colourful stretch of the highland calendar. The trade-off is cold nights in San Cristóbal, down to 4-8°C, and the highest hotel rates and busiest churches of the year in the villages.
- Period
- March to early May
- Rating
- Very good, warmer and drier
- Description
- Still within the dry season, with San Cristóbal warming into more comfortable daytime highs and the coast and jungle at their hottest and driest before the rains arrive. Semana Santa (Holy Week, dated by the lunar calendar, typically late March or April) brings a second peak in crowds and prices, especially in San Cristóbal and Chiapa de Corzo. Late April into May can turn hazy statewide from agricultural burning ahead of the rains, which softens mountain views.
- Period
- June to August
- Rating
- Good with afternoon rain
- Description
- The rainy season begins with a predictable pattern rather than all-day downpours: mornings are typically clear and humid, with heavy but short thunderstorms arriving most afternoons, especially in the jungle and highlands. Waterfalls run fuller but can turn brown with sediment after a heavy storm. Vegetation is at its greenest and the Sumidero Canyon's walls run with seasonal cascades. Fewer international visitors are on the road, and rates in San Cristóbal ease from the January-April peak.
- Period
- September to October
- Rating
- Avoid if possible
- Description
- The wettest two months of the year statewide, when tropical storms and hurricane-season moisture off both coasts can bring sustained multi-day rain rather than short afternoon showers. Highway 199 between Ocosingo and Palenque is at its highest risk of landslides and washouts in this window, Agua Azul frequently runs brown rather than turquoise, and river crossings to Yaxchilán can be cancelled if the Usumacinta rises. This is also low season, so the trade-off is the lowest hotel rates and emptiest sites of the year for travellers willing to build in flexible days.
Best: Late
Avoid: September and October, when tropical-storm rainfall peaks and the Ocosingo-Palenque highway carries the highest landslide risk
Notes: There is no single ideal month for every zone at once: San Cristóbal is coldest exactly when Palenque and the coast are most pleasant, from December to February, so packing for both extremes is unavoidable on a state-wide itinerary.
Summary: Late November through April, the dry season across all five climate zones

- Items
- Period
- Fiesta Grande de Chiapa de Corzo, 8-23 January
- Level
- Very high
- Description
- The single busiest fortnight of the year in Chiapa de Corzo and a significant draw for San Cristóbal as a base; hotel rooms in both towns should be booked months ahead, and rates rise sharply for the Parachicos processions and the Combate Naval finale on 21 January
- Period
- Semana Santa (Holy Week, March or April)
- Level
- Very high
- Description
- San Cristóbal, Chiapa de Corzo and the highland villages fill with domestic Mexican travellers on the biggest national holiday week of the year; processions and Passion plays draw crowds and accommodation books out well in advance
- Period
- Christmas to New Year (mid-December to early January)
- Level
- High
- Description
- A second major domestic holiday peak, concentrated in San Cristóbal and Palenque; the Virgin of Guadalupe pilgrimage on 12 December adds an earlier spike specific to San Cristóbal
- Period
- Late December to February (dry-season peak)
- Level
- High to moderate
- Description
- The main international high season, when clear skies, cold-but-dry highland weather and the strongest waterfall flow draw the bulk of foreign visitors; Palenque and the Sumidero Canyon boats are at their busiest mid-morning
- Period
- July and August (northern hemisphere summer)
- Level
- Moderate
- Description
- A secondary bump from North American and European family travel during school holidays, tempered by the rainy-season weather; still noticeably quieter than the December-April peak
- Period
- June, September and October (deep rainy season)
- Level
- Low
- Description
- The quietest months for both domestic and international visitors, with the lowest hotel rates of the year; the trade-off is the highest risk of highway disruption on the Palenque road and inconsistent waterfall colour, especially in September
