Weather in Arequipa in April

Prime time. April is about as good as Arequipa gets. Highs average 25.6 °C, lows 11.9 °C, and rain falls on 2 days — nothing in the month is working against you.

Arequipa barely has seasons. April scores 97 out of 100 against a best of 100 in May — a gap small enough that the month you choose matters far less here than the week you choose.

Rain falls on only 2 days, so an itinerary with no wet-weather fallback is a reasonable risk. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average April reaches 30 °C. Across the twenty years measured, the hottest April day reached 29.3 °C and the coldest night fell to 5.7 °C.

April is dependably dry, and that reliability is the point: across the twenty years measured, the wettest April on record still only managed 24 mm, and the driest managed 0 mm. There is no meaningful variability to plan around, which makes this one of the few months anywhere that you can build a fixed outdoor itinerary against without a fallback. The wettest single day in twenty years of Aprils brought 11 mm. Rain simply is not the variable that decides this trip — heat, crowds and cost are.

Wind is light at 7.8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 56%.

How April sits in the year

Temperatures hold steady either side: 25.3 °C in March, 25.6 here, 25 in May. Nothing about the timing within the month matters much.

Daylight in April

Arequipa sits close enough to the equator that daylight barely moves all year — 11.7 hours in April, against a range of just 1.9 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

An inland climate

Despite being inland, the year stays fairly even: 17.9 °C between the year's warmest afternoons and coldest nights. At 2397 m, altitude is doing as much work here as latitude: thinner air means fierce sun by day and heat that leaves the moment it sets.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

April in Arequipa versus nearby

If Arequipa is one option among several, the nearby comparison is worth making. Arica is the weaker option in April — 8.1 °C warmer, 2 days less rain. Cusco is the weaker option in April — 9 °C cooler, 5 days more rain.

So: April is effectively as good as it gets here — 3 points behind May, which is inside the margin where the weather stops being the deciding factor and price starts being it.
