Buenos Aires and Medellín
The verdict for April
Mild autumn and book fair
+Mild weather and Buenos Aires International Book Fair around the end of the month.
–Rain showers and busy book-fair days.
April is a very comfortable month for walking, with autumn colour in parks. The Book Fair usually starts in late April.
First rainy season
+Green hills and lower prices.
–Frequent afternoon rain.
April is wetter, but mornings are often pleasant for outdoor plans.
Scores and crowd levels are my own judgement; temperatures are monthly averages. Higher scores are better: quieter, cheaper and more pleasant.
Another month
