Oaxaca is highland tropical — pleasant year-round temperatures with a distinct rainy season. March–April, October–November are the driest, clearest months, with the food, culture, mountains side of the city at its most accessible. The rest of the year still works but expect afternoon showers and occasional washed-out days.

Sweet Spots
If you’re optimizing for the trade-off between weather, crowds, and price, the strongest weeks tend to be at the edges of the best-month window — the first half of March and the last weeks of November. Peak weather is locked in but the Oaxaca of those bookend weeks isn’t yet (or no longer) at full tourist capacity. Local festivals and the post-rain green-everywhere window are bonus signals to chase.
When to Avoid (and the Exceptions)
If you can flex your dates, the months that consistently disappoint most Oaxaca travellers are January–February, May. That said, off-season has its compensations — the obvious one is price (accommodation can drop 30–50%), the subtle one is what locals call the ‘real’ version of the place: no queues, no tour buses, and everyday life running at its actual pace.
