Weather in Stuttgart in April

A good month. April is a solid month to be in Stuttgart. Highs average 15.4 °C, lows 4.5 °C, and rain falls on 10 days — nothing in the month is working against you.

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

Rain on 10 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 15.4 °C days and 4.5 °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: 4 nights fall below freezing. Across the twenty years measured, the hottest April day reached 29.1 °C and the coldest night fell to -4.4 °C.

April is moderately variable: 2 mm in the driest year against 101 mm in the wettest, around an average of 47 mm. Roughly two Aprils in three land near that average, and the third does something else entirely.

Wind is light at 8.7 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: 5.2 °C warmer than March, and May adds another 3.8 °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

13.6 hours of daylight, gaining 1.7 hours across the month. That is between Stuttgart's extremes of 16.1 and 8.3 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 28.3 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

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 Stuttgart versus nearby

If Stuttgart is one option among several, the nearby comparison is worth making. Frankfurt am Main is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Colmar is close enough to be a coin toss — within a degree on temperature, 1 day more rain.

So: April works, with September the better month by 13 points if the dates can move. If they cannot, nothing here should stop you booking.
