Meteo Riserva nazionale di Paracas in dicembre

Most of Peru's December forum chatter is really about the Andean highlands around Cusco and Machu Picchu, where the wet season is just getting going - that's a different climate story entirely from Ica's coastal desert. Ica itself stays close to its year-round dry, sunny pattern regardless of what the Andes are doing at the same time, with real rain a genuine rarity here even in December. It's worth remembering these are two separate weather systems within the same country when planning a Peru itinerary that includes both.

Regulars are direct this isn't real beach weather here, Peru sitting in the Southern Hemisphere so this counts as winter, coastal conditions running cool and often misty. Our row backs that mild, genuinely dry read, 18.8C over 14.7C nights, with rain entirely absent and a real 20.7 kph wind that regulars specifically flag as picking up hard in the afternoons. Regulars are consistent daytime conditions stay comfortable enough for sightseeing and nature tours even if not hot, though anyone hoping to use a hotel pool should check it's heated first, since most aren't this time of year. The sea sits at 19.3C. The record: 10.5 hours of sun, humidity 81 percent and AQI 41.

Regulars are direct that this is winter here and, while daytime temperatures stay comfortable, the wind picks up strongly in the afternoons - strong enough that a heated pool loses its appeal once the breeze sets in. Our row backs the dry, cool-but-not-cold read, 19.6C over 15.6C nights, with rain essentially never happening, 0.5mm and effectively zero rainy days. One regular's late-June visit was summed up simply as nice but certainly not hot, consistent with a destination whose desert coastal climate keeps humidity surprisingly high, 82 percent, without translating into rain. The sea sits at 20C. The record: 10.2 hours of sun, a 20.1 kph wind and AQI 35.

The question regulars answer here is not what May is like but which part of Paracas you stay in, because the wind is not the same across a town this small. The bay is called out as the windy part; the afternoon is when it arrives, and one visitor found it hot and windy at the same time. They also mention high humidity, mostly partly cloudy at midday, and a sea around 17C - we have 19.7C, still cold enough to rule out casual swimming. Our row explains the humidity without any rain behind it: 0.1mm and no precipitation days at all, at 81 percent. This is desert that gets its moisture from the sea. The record: 21.3C days over 16.3C nights, 10.5 hours of sun, a 20.2 kph wind and AQI 36.

February is described as Peru's wettest month, with heavy rain, washed-out roads and cancelled flights - and none of that is about here. That is the highlands. On the coast February is summer, and regulars name Lima and Paracas specifically as having great weather now: our row gives 26.5C over 20.4C with 5.1mm across 1.3 precipitation days. It is the country-versus-destination problem along an altitude axis rather than a coastal one, and a single national sentence about February gets Paracas exactly backwards. The Humboldt still runs, so the sea is 18.7C under a day that reads as 30C - warm air, cold water, the Peruvian coastal pattern. The record: humidity 80 percent, 10.6 hours of sun, a 19.5 kph wind and AQI 24.
