Daily maximum temperatures

The highest daytime temperatures in Colombia are reached in March with an average of 30.8 °C. The coldest month, on the other hand, is June, with an average of just 29.7 °C. In Costa Rica, April is the warmest month, with 30.1 °C. There, it is coolest in November with an average of 27.6 °C.

Night time lows

At night, it cools down to varying degrees depending on the country and altitude. In Colombia, temperatures drop as low as 21.8 °C in June. The warmest nights are in March at 22.4 °C. In Costa Rica, it is coolest at night in February at 19.0 °C and warmest in May at 19.7 °C. This corresponds to a cooling of 7.9 to 8.9 °C in Colombia and 8.4 to 10.5 °C in Costa Rica.

Water temperatures

Humidity

The humidity of the air depends to a large extent on the air temperature. The warmer the air, the more water it can absorb. At a temperature of 25°C it is 23 grams per cubic meter, at 30 degrees it is already 26 grams. Therefore, the air humidity is given as a relative value to the temperature-dependent maximum amount. It becomes unpleasant when high humidity is combined with high temperatures.

Humidex

Humidex is an approximate, sensed temperature calculated on the basis of air temperature, dew point and humidity. It was developed in 1965 by the Canadian meteorologists J. M. Masterton and F. A. Richardson. Since the wind speed is ignored here, it is not very meaningful in areas below approx. 15°C. Above that, it is more reliable, since at higher temperatures humidity plays a greater role than wind.

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. May brings the most rainy days (15.0) in Colombia. With an average of only 7.1 days, February is the friendliest. In Costa Rica, it rains most often in September with 19.7 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 Colombia occurs in May, when about 8.8 liters per square meter fall per day. In Costa Rica, the average amount of precipitation ranges from 2.0 liters per day in February to 10.2 in October. 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

With 2,263 hours of sunshine per year, Costa Rica is in the lead. The most hours of sunshine (8.7 per day) are in March. Colombia falls into second place with only 1,971 hours. There the sun is visible in May for only 4.6 hours per day, so not hidden behind clouds.

Hours of daylight

The length of a day varies throughout the year and depends on the distance from the equator. In January, the day in Colombia is only 11.9 hours long. In June, on the other hand, it is 12.4 hours. In Costa Rica, it is 11.6 hours in December and 12.7 in June.
