Best time to visit Buenos Aires
Argentina · 20-year averages
Buenos Aires has no real season. The best month scores 83 and the worst 66, a spread of just 17 points, so the honest answer to "when should I go" is whenever the flights are cheapest. 9 of the twelve months sit within ten points of the best, so there is more than one right answer.
January is the warmest month at 27.6 °C and July the coolest at 13.2 °C — a 14.4 °C spread across the year.
Rain is spread evenly through the year — between 6 and 9 wet days in every month — so there is no dry season to aim for and no wet one to dodge. Whatever you plan, the odds of rain are much the same.
Daylight runs from 9.8 hours in winter to 14.5 in summer, enough to notice on a sightseeing itinerary.
The three strongest months are April, November, December. The one to think twice about is July. Each month below has its own page with rainfall reliability, extremes, daylight and crowd levels.
