Colombia in September: A Mix of Sun and Rain

September ushers in the rainy season in Colombia, which also marks an end to the high tourist season. But despite rain showers, the water level in the Amazon is still low. Exploring and hiking in the rainforest is still possible during this time. Elsewhere, you can revel in the beauty of Tayrona National Park in Santa Marta or watch the migration of humpback whales off the Pacific coastal villages like Nuqui. The Caribbean and the Pacific coasts also invite visitors to relish the pleasant climes before the rainy season intensifies in October.

Weather can be unreliable in some parts of the country, yet there are plenty of places to visit in Colombia in September. We recommend checking with the weatherman before your Colombia trip.
