Being close to the equator (3 ° southern latitude) there is only a small seasonal changes in the day length. There are only two seasons , a longer rainy and a shorter dry season. The climate is hot all year round. At night, the air humidity reaches at least 95% and it is also often very high during the day, so that the air temperature is perceived as even warmer than actual: it almost always "muggy".
During the rainy season from December to May, strong thundershowers occur almost daily. The amount of precipitation per year reaches 2000 millimetres, the triple of an average amount in Central Europe. The average temperatures of each month of the year vary only very slightly between 26 and 28 °C. The maximum temperatures mostly lie between 28 and 35 °C, while at night temperatures fall to minima between 20 and 30 °C. This results in monthly averages between 26 and 28°C. The lowest recorded tempeture was 13°C.
Lloró is close to the equator (5° Northern latitude) on the west flank of the Andes. It is one of the places with the highest yearly precipitation total - more than 13'000 millimetres (13 meters!) of rain fall per year.
Debundja, Cameroon, is situated on the West Coast of Cameroon, about 450 Km north of the equator (4.12° Northern latitude) at the feet of 4040 meter Mount Cameroon. This massive mountain blocks the clouds coming in from the ocean and increases precipitation, especially on the western flank. Yearly precipitation totals recorded at Debundja are 9'100 millimetres (9.1 meters!) of rain fall per year as average over 30 years.
