Weather | 8–17°C (46–63°F) with cooler mornings and more changeable skies | 10–20°C (50–68°F), mild days, better light, and more comfortable evenings | 13–24°C (55–75°F), warmer and more reliably sunny |
Crowds | Moderate, with shoulder-season breathing room | Moderate to high, especially at Easter and on sunny weekends | High, with major sites firmly in peak rhythm |
Atmosphere | Early spring, quieter streets, locals reclaiming outdoor tables | Full spring feel, roses, azaleas, open-air lunches, and longer walks | Early-summer energy without August shutdowns |
Key events | Possible early spring exhibitions and marathon spillover | Easter observances, Natale di Roma on April 21, Liberation Day on April 25 | May Day on May 1, concert season, and busy spring weekends |
Public holidays | Fewer holiday-driven spikes | Easter dates vary, plus April 25 can affect openings and transport | May 1 can mean closures or reduced service |
Budget | Often softer hotel rates than April | Higher around Easter week and holiday weekends | Similar or slightly higher than April at popular stays |
Best for | Lower crowds and museum-heavy trips | First-time visits, walking days, and spring city breaks | Outdoor-heavy itineraries and garden time |
Book early? | Nice to do for Borghese and Vatican | Yes, especially Vatican, Colosseum, Borghese, and central hotels | Yes, especially for weekend travel and headline attractions |
Transport tips | Metro and buses are straightforward | Allow extra time near the Vatican and historic center on holiday dates | Expect heavier traffic and busier hop-on hop-off routes |
