Quick Answer
October through May is Oaxaca’s dry season, making it the most comfortable period for exploring the city’s markets, colonial architecture, and archaeological sites. The Day of the Dead (October 31–November 2) draws visitors from across the world and is worth planning a full trip around. Discover Oaxaca City in depth and book accommodation well ahead for any festival visit.
Season Overview
Oaxaca sits at 1,550m in a valley surrounded by mountains, which moderates temperatures year-round. Rain, not heat, is the primary seasonal variable.

Peak Season: October to December (and Holy Week)
Oaxaca has two distinct peak windows. The first, and most famous, is Day of the Dead (Día de los Muertos). The cemeteries of Xoxocotlán and San Miguel del Valle fill with marigolds and candlelit altars on the night of November 1–2, and the Zócalo and Mercado Benito Juárez are alive with activity from October 28 onward. Hotels across the city book out months in advance - budget guesthouses and boutique hotels alike. Prices double or triple for the November 1–2 period.
December brings Christmas energy with posadas, nativity processions, and the festive Zócalo. This is also when many mezcal producers open their palenques (distilleries) for tours.
Semana Santa (Holy Week, March/April) is a second peak window. Oaxacan Easter processions are among Mexico’s most elaborate, with large crowds gathering in the historic centre.
Shoulder Season: March, April, and January
January through April delivers reliable dry-season conditions without the extreme festival pricing. March and April are particularly pleasant - temperatures peak around 28–30°C, skies are clear, and the city’s famous food markets (Mercado 20 de Noviembre for tlayudas, Mercado Benito Juárez for mezcal tastings) are accessible without crowds. Day trips to Monte Albán are best in the dry season when the hilltop paths are dry underfoot.
January is excellent for value-conscious visitors: post-holiday prices apply, skies are clear, and the chocolate, mezcal, and textile workshops around the city centre are fully open.
Off Season / Rainy Season: June to September
The rainy season brings daily afternoon downpours - typically 2–5pm - but mornings are reliably clear and evenings usually dry. The main drawback for archaeological site visits: Monte Albán’s exposed hilltop plateau and the tombs at Mitla become slippery and partly inaccessible in heavy rain.
The notable exception is the Guelaguetza Festival, held on the second and third Mondays of July. This showcase of indigenous dance, music, and costume from Oaxaca’s eight regions is one of Mexico’s most important cultural events. The main auditorium on Cerro del Fortín holds around 11,000 people; tickets for the seated sections sell out far in advance. Even during this busy week, accommodation outside the immediate city centre is often available.
