The best months to visit Stuttgart are May, June and September. June brings an average high of 23.7 °C with 13 rain days, while September settles into a comfortable 20.7 °C high and just 10 rain days — the fewest of any month — making both easy for exploring Schlossplatz on foot. July and August are peak season, when school holidays fill the city and the squares with crowds. Winter is the quiet low season, cold and short on daylight, but atmospheric around the Christmas markets.

How the months are picked.A month qualifies when its average high sits in the comfortable 20–28 °C band (scored down towards 9 °C and 37 °C), rain days are few and sunshine hours are high — at least 78 % of the city's best-scoring month. July and August are then set aside as peak season (school-holiday crowds and prices) whenever at least three other months qualify; where summer is the only comfortable window they stay. Figures are ten-year averages (2016-01-01 to 2025-12-31) from ERA5 reanalysis data via Open-Meteo (CC BY 4.0) for the city centre coordinates.
