Sardinia May — Sant Efisio procession in Cagliari

#1 of 12 months

Best match

Sant Efisio fills Cagliari with traditional costumes — the islands single best week.

August trade-offs

  • Peak Italian holiday — hotel rates 3-4x May, last-minute availability impossible
  • Beach parking fills by 8am at every name beach; some bays cap daily entry at 500
  • Wildfire risk highest of the year — multiple trails and reserves close on red days

May trade-offs

  • Sea at 18C — viable but cold-shock on entry
  • Mistral wind picks up in late May and can blow out east coast beach days
