Weather in Palermo in April

Prime time. If you get to pick your dates, April is the one. Highs average 20.1 °C, lows 12.4 °C, and rain falls on 9 days — nothing in the month is working against you.

April ranks 3 of 12 in Palermo. Only May scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 9 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. 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 28.7 °C and the coldest night fell to 6.5 °C, and the wettest single day dropped 45 mm — roughly 80% of the month's rain in one day.

April is moderately variable: 7 mm in the driest year against 114 mm in the wettest, around an average of 56 mm. Roughly two Aprils in three land near that average, and the third does something else entirely.

Wind is light at 11.2 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 76%, high enough to notice on the warm days without dominating them.

How April sits in the year

The month is on the way up: 3.1 °C warmer than March, and May adds another 3.9 °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

13.1 hours of daylight, gaining 1.2 hours across the month. That is between Palermo's extremes of 14.8 and 9.5 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 15.9 °C in April — cold — a quick dip rather than a swim, and a wetsuit if you are in for longer. The sea peaks at 27.2 °C in August and bottoms out at 14.2 °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

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 Palermo versus nearby

If Palermo is one option among several, the nearby comparison is worth making. Catania is close enough to be a coin toss — 2.2 °C warmer, 2 days less rain. Taormina is close enough to be a coin toss — within a degree on temperature, 1 day less rain.

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