Weather in Positano in April

A good month. April works. It is not the peak, but nothing about it fights you. Highs average 16.3 °C, lows 14.1 °C, and rain falls on 9 days — nothing in the month is working against you.

April ranks 7 of 12 in Positano: past the worst of the year but short of July, which is the month to book if the dates are open.

Rain on 9 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 16.3 °C days and 14.1 °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: the day barely swings — 2.2 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest April day reached 22.6 °C and the coldest night fell to 6.9 °C.

April is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest April on record still delivered 100 mm against 15 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 57 mm average is a reasonable planning figure, not a promise.

Wind is light at 12.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 79%, high enough to notice on the warm days without dominating them.

How April sits in the year

The month is on the way up: 2.1 °C warmer than March, and May adds another 3.4 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in April

13.2 hours of daylight, gaining 1.3 hours across the month. That is between Positano's extremes of 15.1 and 9.3 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 15.8 °C in April — cold — a quick dip rather than a swim, and a wetsuit if you are in for longer. The sea peaks at 26.7 °C in August and bottoms out at 14.3 °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

Shoulder. The value months — prices ease off and you get the place closer to itself.

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

April in Positano versus nearby

If Positano is one option among several, the nearby comparison is worth making. Naples is a better bet in April — 3.2 °C warmer, 1 day more rain. Bari is a better bet in April — 2.9 °C warmer, 1 day more rain.

So: April is a compromise. July is 20 points better and is what Positano is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
