Weather in Vienna in April

A good month. April works. It is not the peak, but nothing about it fights you. Highs average 16.8 °C, lows 5.5 °C, and rain falls on 9 days — nothing in the month is working against you.

April ranks 2 of 12 in Vienna. Only September scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 9 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 16.8 °C days and 5.5 °C nights; the spread matters more here than any single number.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest April day reached 29.2 °C and the coldest night fell to -4.3 °C.

April is moderately variable: 2 mm in the driest year against 77 mm in the wettest, around an average of 41 mm. Roughly two Aprils in three land near that average, and the third does something else entirely.

Wind is light at 8.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 72%.

How April sits in the year

The month is on the way up: 6.1 °C warmer than March, and May adds another 4.3 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short. Rain is the thing that moves: May brings 7 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in April

13.6 hours of daylight, gaining 1.7 hours across the month. That is between Vienna's extremes of 16 and 8.4 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 30.8 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead.

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

April in Vienna versus nearby

If Vienna is one option among several, the nearby comparison is worth making. Graz is close enough to be a coin toss — within a degree on temperature, 1 day more rain. Budapest is close enough to be a coin toss — within a degree on temperature, 2 days less rain.

So: April is effectively as good as it gets here — 4 points behind September, which is inside the margin where the weather stops being the deciding factor and price starts being it.
