Oaxaca in January — Full Picture
January in Oaxaca is the heart of the dry season — sunny, mild, and one of the best months to visit. It averages 28°C by day and a cool 8°C at night, with almost no rain (5mm).
Clear blue skies and warm afternoons make January ideal for Monte Albán, Hierve el Agua, and the valley craft villages. The high-altitude sun is strong even when the air feels mild — a hat and sunscreen matter.
The big swing between warm days and cool nights is the thing to plan for: light clothes by day, a sweater after sunset. Mornings can be crisp.
The New Year holiday keeps the first week busy, and Three Kings' Day (Jan 6) brings the traditional Rosca de Reyes bread. The post-Christmas high season tapers through the month, so hotels stay in demand but ease from the December peak.
What to Wear & What to Pack
Peak dry season — sunny, warm days around 28°C and cool nights near 8°C. Light clothing for the day, but pack a sweater or light jacket for chilly evenings at 1,555m altitude. Hat, sunglasses, and SPF for the strong high-altitude sun.
