Weather in Lima in April

Prime time. April is about as good as Lima gets. Highs average 30.4 °C, lows 23 °C, and rain falls on 0 days — nothing in the month is working against you.

Lima barely has seasons. April scores 85 out of 100 against a best of 94 in July — a gap small enough that the month you choose matters far less here than the week you choose. Worth keeping in perspective: April is the weakest month of Lima's year and it is still a perfectly good one. The downside here is small.

Rain is not a factor worth planning around this month. Pack for 30.4 °C days and 23 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 20 days top 30 °C, making the heat continuous rather than occasional. Across the twenty years measured, the hottest April day reached 33.3 °C and the coldest night fell to 20.1 °C.

April is dependably dry, and that reliability is the point: across the twenty years measured, the wettest April on record still only managed 5 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 1 mm. Rain simply is not the variable that decides this trip — heat, crowds and cost are.

Wind is light at 8.2 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 71%.

How April sits in the year

Temperatures hold steady either side: 30.8 °C in March, 30.4 here, 29.6 in May. Nothing about the timing within the month matters much.

Daylight in April

Lima sits close enough to the equator that daylight barely moves all year — 11.8 hours in April, against a range of just 1.4 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

Sea temperature

The sea sits at about 20.4 °C in April — swimmable, but it takes a moment to commit. The sea peaks at 22.7 °C in February and bottoms out at 16.6 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

How busy it gets

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

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

April in Lima versus nearby

If Lima is one option among several, the nearby comparison is worth making. Trujillo is the weaker option in April — 6.2 °C warmer, 6 days more rain. Cusco is close enough to be a coin toss — 13.8 °C cooler, 7 days more rain.

So: April works, with July the better month by 9 points if the dates can move. If they cannot, nothing here should stop you booking.
