|Climate chart (explanation)|
Andagoya has one of the most monotonous climates in the world. Its annual range of mean monthly temperatures – that is to say, the difference between the warmest and coldest months – at Andagoya is mere 0.7 °C (approximately 1.3 °F) as April, the warmest month, has an average temperature of 27.7 °C (81.9 °F) while November, the "coldest" month, averages 27.0 °C (80.6 °F); the average annual temperature is 27.4 °C (81.3 °F). This near complete uniformity of temperature is caused by the fact that Andagoya, at a latitude of 5°5' North, lies extremely close to the thermal equator, which is situated a few degrees north of the astronomical equator because the Earth reaches perihelion (its closest position to the Sun in its orbit) in early January and is at aphelion (furthest away) in early July, causing places located precisely at the equator to receive somewhat more insolation (i.e., light and heat energy from the sun) in January than in July even though the height of the sun and the length of days would be the same at both times. At a few degrees north latitude, however, the perihelion/aphelion factor and the slightly higher sun and longer days experienced at the time of the summer solstice for the Northern Hemisphere cancel each other out, making the level of insolation experienced there virtually identical throughout the year.
Every month of the year has at least 495 millimeters (19.5 inches) of average precipitation (March and December both averaging this figure), with the wettest month (April) averaging 663 millimeters (26.1 inches). Average annual precipitation is 7,089 millimeters (279.1 inches), and more rain falls at night than during the day, the reverse of what is true in most places that have tropical rain forest climates.
