St. Peter’s Square & Basilica
May brings comfortable, sun-dappled days that hover between 16-22°C, ideal for lingering in the square after a basilica visit. Tourist numbers rise, especially around midday, so arrive early to avoid long queues and the heat that builds on travertine and roof tiles. Evenings are pleasant for taking in the illuminated façade; pack a light jacket for after-sunset breezes off the Tiber.
Vatican Museums & Sistine Chapel
May offers warm, steady days outside that reduce the pressure of winter rain pushing people indoors, though the museums remain busy as shoulder-season tourism peaks. Afternoon lighting in the galleries is forgiving and outdoor sculpture spaces are pleasant for a break. Book tickets in advance, pack a small bag (large luggage is not allowed), and expect lines to the cloakroom and security at peak hours.
Vatican Gardens & Walls (and interface with Rome)
May shows the Gardens lush and well-watered, with pleasant 16-22°C days and aromatic hedges releasing Mediterranean scents; guided tours multiply with the tourist season. Early morning or late-afternoon slots avoid the midday heat and give the best photographic light across the papal villas and terraces. The adjoining Borgo area is lively, and it’s sensible to combine the gardens with a walk along the city walls into Trastevere.
