Peru - weather in April

April in Peru is an autumn month, although, in the northern part, close to the Equator, the temperature is practically the same as in the previous months. Instead, in the southern part of the Andes, the night temperatures begin to decrease, while in the central and southern part of the coast (see Chiclayo, Lima, Pisco, Marcona), the cool sea current begins to be felt more, and the temperature decreases by a couple of degrees Celsius.
In the east, in the Amazon forest (see Iquitos, Pucallpa, Puerto Maldonado), April is a hot, muggy and rainy month, although in the southern part (see Puerto Maldonado), the rains begin to decrease.
In the Andes (see Cajamarca, Cusco, Machu Picchu), where daytime temperatures are stable throughout the year, night temperatures, as mentioned, begin to decrease. At the highest altitudes it gets cold at night, and especially in the south and above 3,500 meters (11,500 feet), the temperature can drop below form (see Juliaca). The rains in the Andes begin to decrease as the winter, which is the dry season, approaches, and in the extreme south, near the Atacama desert (see Arequipa, Tacna), they are already completely absent.
On the low-altitude desert plateau between the Andes and the coast (see Ica, Nazca), around 500 meters (1,650 feet), it is hot, and rainfall is very rare or completely absent.
On the coast, where the climate is arid or desert due to the cool Humboldt current, April is a hot and muggy month only in the extreme north (see Tumbes), while in the rest of the coast (see Trujillo, Lima, Pisco, Marcona), it is a pleasantly warm and quite sunny month (although in the morning, there may be some mists and clouds). The rains are completely absent in most of the coast, except in the extreme north.
However, in El Niño years, the northern part of the coast, up to the Lambayeque region, becomes hotter and rainier, and when the phenomenon is most intense, it becomes fully tropical, with abundant rains.

The sea is warm enough for swimming in the far north (see Tumbes), while in the rest of the coast it is cooler, especially in the stretch from Lima to Marcona, where it drops to around 20 °C (68 °F), because the effects of the Humboldt current are felt more.
However, the sea gets warmer than usual in El Niño years, while it gets cooler in La Niña years.
