Ica weather in May

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.

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.

Forum posters describe June as winter in this coastal desert region, with comfortable daytime temperatures around Ica and nearby Paracas but genuinely strong afternoon winds worth planning around. Posters are careful to distinguish this coastal desert climate from Peru's much colder Andean highlands (Cusco, Puno and similar high-elevation stops on a broader itinerary), where nighttime temperatures can drop toward freezing and heavy layering is standard advice - conditions in Ica and at the Huacachina oasis specifically stay milder than that highland cold even in June. Posters note June's relative quiet is a real plus at Huacachina, with the sand dunes seeing lighter crowds than peak season.
