Pisa weather in September

Regulars split the month cleanly: the first week or two can still push into the upper 80s to lower 90s Fahrenheit and carry the risk of a short, sharp late-summer storm, while the back half is called more reliable and comfortable overall. Our row backs the average across that swing, 28.5C reading as 29C over 15.3C nights, with 94mm of rain across 9 days. Regulars specifically flag the hills surrounding the city as a source of fast-forming storms that can arrive with little warning even on an otherwise clear day, rarely lasting more than a day when they do. The standard packing advice is a light wind-breaker and a small umbrella rather than full rain gear. The record: humidity 72 percent, 10.1 hours of sun, an 11.9 kph wind and AQI 44.

Regulars are honest this month genuinely comes down to luck, southern Italy usually running warmer but the weather itself capable of doing unexpected things regardless of region. Our row backs that mild, genuinely wet read, 19.3C over 7.7C nights feeling 6C, with a substantial 86.9mm of rain across 10 days and humidity at 73 percent. Regulars are consistent this falls within the broader April-to-late-June window locally considered the most comfortable stretch of the year, occasional showers alongside cool evenings the realistic expectation rather than a guaranteed sunny trip. The sea sits at a cool 15.7C. The record: 10.9 hours of sun, a 12.3 kph wind and AQI 46.

June is inside the stretch the Pisa forum rates best - April to late June, then September and October - and it is also the last month before the full summer, with more variability than July and August but generally hot and sunny. The advice for the tower itself is about the hour: book ahead, and go first thing in the morning or late in the afternoon, which dodges the midday coach crowds and gets the better light for photographs at the same time. Regulars describe the Campo dei Miracoli in high summer as simply very crowded, which is the argument for late June over July. The record: 28C days that feel like 31C, 16.4C nights, 7.7 precipitation days, 13.2 hours of sun and a 24.3C sea.

Forum posters name November as Pisa's rainiest month, with October and November together seeing the heaviest precipitation of the year. Temperatures ease through the month - low-to-mid teens Celsius early on if you're lucky, dropping to around 10C or below by the back half - and posters describe real year-to-year variation in how much of the month is actually wet: one traveler's 11-day November trip saw rain on 4 days, only 2 of those heavy. Posters recommend simple layering (t-shirt, fleece, thin waterproof jacket) as generally sufficient, noting that street umbrella-sellers appear within minutes of any downpour starting. The trade-off for the wetter weather: noticeably thinner crowds around the Leaning Tower compared to peak season.

Pisa's forum rates April through late June, plus September-October, as the most comfortable stretch of the year — warm days around 20°C with cooler mornings and evenings, ahead of peak summer heat and crowds. Regulars are candid that May itself can be genuinely unsettled some years, with forecasts only reliable about 48 hours out, so packing for a rainy day alongside the sunny ones is standard advice.
