Seasonal Climate Variations / When to Go

These winter months tend to see the least rainy weather, averaging around 63 mm / 2.5 inches per month, and so an umbrella is less likely to be a necessary item of luggage than in January and February, which each feature around 120 mm / 4.7 inches of rain. Occasionally during the winter, snow arrives in Buenos Aires and the city has even seen heavy blizzard in recent years, although this is somewhat unusual.
