The best months in detail
March, April, May, September, October, November.
Weather is optimal, sights are open and uncrowded relative to peak season, and you have the city closer to how locals enjoy it. Book accommodation 2–3 months ahead — these months sell out.
February, December.
Slightly less ideal weather but cheaper prices and fewer tourists. If you can handle the trade-off, these months can be the smartest pick — you get most of the experience for less money.
June–August (winter smog buildup from the Andes basin trapping pollution, plus cold).
Either weather is uncomfortable, key sights are closed, or prices are at peak with maximum crowds. Skip unless a specific event (festival, family commitment) makes it worth it.
