Peru - weather in February

February in Peru is a summer month, and is the warmest of the year in much of the coast.
In the east, in the Amazon forest (see Iquitos, Pucallpa, Puerto Maldonado), February is a hot, muggy and rainy month.
In the Andes (see Cajamarca, Cusco, Machu Picchu), where the temperature varies with altitude, we are in the warmest and rainiest period of the year. However, the rains are not particularly abundant, on the contrary, in the extreme south, near the Atacama desert (see Arequipa, Tacna), they are scarce or completely absent. Despite the period, 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 freezing (see Juliaca).
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, February 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 warm but without excesses and quite sunny (although mists and clouds can form in the morning). The rains are completely absent in most of the coast, except in the far north, where this is the rainiest month.
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 can be considered warm enough for swimming everywhere, however, it is warmer in the north (see Tumbes, Talara, Piura) and in the south (see Mollendo, Ilo), where it reaches o it exceeds 24 °C (75 °F), while in the central part, roughly from Chiclayo to Marcona, it is paradoxically a little cooler, around 22.5/23 °C (72.5/73.5 °F), because the effects of the Humboldt current are felt more. February is the month when the sea in Peru is warmest, although in the north the water temperature remains the same also in March.
However, the sea gets warmer than usual in El Niño years, while it gets cooler in La Niña years.
