Even in January it rains over 120 mm, as much as a wet month in many cities. What helps is knowing that storms tend to arrive in the afternoon: mornings are the best time for the river.

Today's weather and rain in the rivers

For the day's forecast use a weather app or the IDEAM site. What they do not tell you is that a downpour upstream can raise the river even when it is dry in town. If the water changes color or carries branches, get out. There are more safety tips in San Rafael river pools.

What to pack

If it rains, there are indoor plans in things to do in San Rafael, and some hotels in San Rafael have pools so the day is not lost. Plan the trip in getting there from Medellín.
