Weather in Cusco in April

A good month. April works. It is not the peak, but nothing about it fights you. Highs average 16.6 °C, lows 6.8 °C, and rain falls on 7 days — nothing in the month is working against you.

April ranks 6 of 12 in Cusco: past the worst of the year but short of August, which is the month to book if the dates are open.

Rain on 7 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 16.6 °C days and 6.8 °C nights; the spread matters more here than any single number.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest April day reached 22.2 °C and the coldest night fell to 3.5 °C, and the wettest single day dropped 92 mm — roughly 209% of the month's rain in one day.

This is the volatile part. April rainfall has ranged from 2 mm to 184 mm across the twenty years measured — a 182 mm spread around an average of 44 mm. The average is real but almost no individual April looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 5.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 84%, high enough to notice on the warm days without dominating them.

How April sits in the year

Temperatures hold steady either side: 16.8 °C in March, 16.6 here, 16.8 in May. Nothing about the timing within the month matters much. Rain has already shifted: 12 days fewer than March had.

Daylight in April

Cusco sits close enough to the equator that daylight barely moves all year — 11.8 hours in April, against a range of just 1.6 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: 13.5 °C between the year's warmest afternoons and coldest nights. At 3312 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

Shoulder. The value months — prices ease off and you get the place closer to itself. April is the value pick for Cusco: it scores within 14 points of August without carrying August's prices.

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

April in Cusco versus nearby

If Cusco is one option among several, the nearby comparison is worth making. Arequipa is a better bet in April — 9 °C warmer, 5 days less rain. Lima is close enough to be a coin toss — 13.8 °C warmer, 7 days less rain.

So: April works, with August the better month by 14 points if the dates can move. If they cannot, nothing here should stop you booking.
