Last two weeks of May: Businesses are open, beach clubs are operating, and prices haven't yet hit peak-season levels — a genuinely excellent window most first-timers overlook.
Second half of June: Warmer sea than May, still meaningfully cheaper and quieter than July-August, with the full range of restaurants and beach clubs operating.
Second half of September: The best all-round value window — warm sea, thinning crowds, and most beach clubs and restaurants still open (unlike October, when many close).
Weeks to avoid if crowds and prices matter: The last two weeks of July and all of August, when Mykonos is at its most crowded and expensive.
