Rain days per month
By definition, a rain day is a day on which at least 0.1 liters of precipitation per m² fall. This corresponds to a 1 square meter puddle in which the water stands 0.1 mm high — insofar as the water does not seep away or evaporate. So it does not have to rain all day long. July brings the most rainy days (0.7) in Atacama. With an average of only zero days, January is the friendliest. In Colombia, it rains most often in May with 15.0 days.
Precipitation amount per day
Depending on the season and the location of a country, the wind brings a varying amount of water with it. As a rule, the water evaporating in the oceans is absorbed and then transported inland. The greatest amount of rain (hail or dew are also forms of precipitation) in Atacama occurs in July, when about 0.2 liters per square meter fall per day. In Colombia, the average amount of precipitation ranges from 3.5 liters per day in January to 8.8 in May. However, these are average values. If you consider that there are only 15.0 rainy days in Colombia in May, each of them accounts for about 17.5 liters.
Sunshine hours per day

Hours of daylight
The length of a day varies throughout the year and depends on the distance from the equator. In June, the day in Atacama is only 10.5 hours long. In December, on the other hand, it is 13.9 hours. In Colombia, it is 11.9 hours in January and 12.4 in June.
