I spent this past Sunday in Sogamoso where the weather was cloudy and had a little rain. (The entire week before it had rained almost every day. I even experienced my first electricity outage due to a severe thunderstorm.)
During my four days (Monday through Thursday) in Eje Cafetero (the coffee axis of Colombia), all of them were cloudy. It rained lightly for two days. I traveled to Bogota for one day (Friday), and on Saturday I flew out to San Andrés. (I'll be here almost a week.) The weather on the island is completely sunny and humid.
