July trade-offs

  • ↓Extreme crowds in Diocletian's Palace: narrow lanes are genuinely uncomfortable at midday
  • ↓Accommodation prices 3–4× what you'd pay in May — budget options fully booked months ahead
  • ↓Bačvice beach shoulder-to-shoulder: restaurants and bars require reservations or patience

September trade-offs

  • ↓First autumn rains returning: 67mm — some September afternoons turn wet unexpectedly
  • ↓Early September still relatively busy; the significant drop comes in mid-to-late September
  • ↓Island ferry frequencies beginning to reduce from summer maximums
