Average monthly and annual values in Stuttgart


April



At the same time as temperature rises, the ambient air concentration of sulphur dioxide continues to drop. The ozone level may be increased for the first time of the year as a result of the first very warm days and the continually rising irradiation. This is true for the city of Böblingen and Stuttgart's harbour, where measurements indicated monthly short-time values of about 150-160 µg/m³, just below the critical level of 180 µg/m³.

While the average ambient air concentration of nitrogen dioxide continues to be nearly constant, peak values are significantly lower (up to 120 µg/m³) than in the winter months due to less inversion weather conditions and better aeration.

It is notorious that April weather is capricious. A trough of low pressure from the North of Central Europe to the South often brings polar air from Greenland on its west side as far as to the Mediterranean region. Through depression, this leads to warm fronts coming from the South. So cold air invasions of late winter go hand in hand with the first advancing of early summer - a weather situation which Goethe describes in the first lines of his "Osterspaziergang". April's average temperature 49.1 °F (9.5 °C) in Stuttgart-Zentrum, 46.8 °F (8.2 °C) in Hohenheim) comes close to the annual average. Maximum temperature can reach almost 86 °F (30 °C), minimum temperature can sink as low as 26.6 °F (-3 °C). The position of the sun at noon is high with about 50 degrees.

Weather lore:

- A cold April, the barn will fill.

- If it thunders on All Fools' Day, it brings good crops of corn and hay.
