Buenos Aires and Medellín
The verdict for March
Warm and returning to normal
+Pleasant weather and a city back in full swing.
–Hotel rates and crowds rise with events.
March is one of the better months: warm days, comfortable evenings and the cultural calendar is active.
Warm and mostly dry
+Comfortable weather and moderate prices.
–Rain begins to return later in the month.
