Traveller notes on Pisa in September
Other months in Pisa
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.
