May (Shoulder Best / Full Season Opens) is Excellent for Mykonos.
Shoulder season best #1 — the canonical sweet-spot month for Mykonos. Climate is ideal (23°C/73°F day, 16°C/61°F night, sea 18°C swimmable), all hotels + restaurants + beach clubs are fully operational, and pricing is 30-40% cheaper than July-August peak with zero Meltemi winds. Cavo Paradiso opens late May for the year's first superclub parties. The trade-off is sea 18°C still cool for prolonged swim (best for short dips). For honeymoon couples or first-time Mykonos visitors who want all the venues open without peak chaos, May is the strongest recommendation alongside September.
