Weather in Nice in April

A good month. April is a solid month to be in Nice. Highs average 15.8 °C, lows 13.3 °C, and rain falls on 8 days — nothing in the month is working against you.

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

Rain on 8 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 15.8 °C days and 13.3 °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 — 2.4 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest April day reached 20.5 °C and the coldest night fell to 8.1 °C, and the wettest single day dropped 45 mm — roughly 80% of the month's rain in one day.

April is moderately variable: 10 mm in the driest year against 149 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 12.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 77%, 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 °C warmer than March, and May adds another 3.1 °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

13.4 hours of daylight, gaining 1.4 hours across the month. That is between Nice's extremes of 15.4 and 9 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 14.5 °C in April — cold — a quick dip rather than a swim, and a wetsuit if you are in for longer. The sea peaks at 24 °C in August and bottoms out at 13.1 °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 Nice versus nearby

If Nice is one option among several, the nearby comparison is worth making. Genoa is close enough to be a coin toss — 2.8 °C warmer, 2 days more rain. Marseille is a better bet in April — 4.1 °C warmer, the same number of rain days.

So: April is a compromise. July is 23 points better and is what Nice is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
