Mykonos in May is pre-peak party-island spring — 23°C / 73°F afternoons, 18°C / 64°F nights, 4 rain days, the beach clubs (Scorpios, Nammos) opening for the season.
Mykonos in May runs Aegean pre-peak resort spring. Hellenic National Meteorological Service (HNMS) data put afternoon highs at 23°C / 73°F and overnight lows at 18°C / 64°F with 4 rain days. The meltemi wind starts ramping in late May. UV index 9-10 (very high). The dressing register is Greek-islands resort with Mykonos's particular party-and-print accent: lightweight cotton or linen in the Cyclades palette (white, blue, sand, terracotta, with more print and color than Santorini's strict white-and-blue), slip-on leather sandals (Ancient Greek Sandals founded Athens 2012; Mykonos Sandals, local custom-leather sandal-makers in Chora), wide-brim sun hat, polarized sunglasses, swim cover-up, light cardigan, SPF 50. Mykonos Town (Chora), the harbor village with Little Venice (the cliff-edge Venetian-era buildings), the Mykonos Windmills (5 surviving 16th-century white-and-thatch windmills), Matoyianni shopping street, and Paraportiani church (the most-photographed Greek church), anchors the city register. The Mykonos beach scene splits into south-coast organized beach clubs (Psarou, Paradise, Super Paradise; Scorpios at Paraga, Nammos at Psarou) and north-coast quieter family beaches (Agios Sostis, Fokos, Panormos). Diane von Furstenberg has a Mykonos boutique; Galatis Mykonos (1968 family-owned boutique) carries the heritage Mykonos resort register.
Mykonos May is the pre-peak party-island spring — the Scorpios beach club opening for the season, the Galatis Mykonos boutique putting the spring resort collection in the window, the white-and-blue-and-print Cyclades register more colorful than Santorini's photogenic minimalism.

Psarou Beach (south coast, Nammos restaurant + beach club, organized — the most-cited Mykonos beach); Paradise Beach (south coast, Tropicana day-club + Paradise Club night-club); Super Paradise (south coast, more bohemian-LGBT than Paradise); Paraga Beach (south coast, Scorpios beach club at the western end — the most-curated Mykonos club); Agios Ioannis (Shirley Valentine beach, west coast); Agios Sostis (north coast, quiet, Kiki's taverna for the most-cited grilled-fish lunch); Fokos (remote north, no organized infrastructure, donkey-and-walking access). Pack: swim, cotton cover-up, slip-on sandals, sun hat, sunglasses, SPF 50.
Ancient Greek Sandals (Athens-founded 2012, the most-recognized contemporary Greek heritage; Mykonos boutique in Chora); Mykonos Sandals (local custom-leather sandal-makers in Chora's narrow alleys, made-to-measure ~€80-150); Galatis Mykonos (1968 family-owned, the heritage Mykonos resort boutique on Panachrantou Street); Ilias LALAoUNIS (Athens jewelry since 1968, museum-curated heritage); Themis Z (Athens contemporary); Diane von Furstenberg Mykonos boutique; Heidi Klein swimwear; Linum Greek heritage textiles. Matoyianni Street and Panachrantou Street in Chora hold the highest concentration.
Scorpios is the most-curated Mykonos beach club — at Paraga Beach on the south coast. Founded 2015 by RoseBar / Soho House alumni. Restaurant + beach + sunset DJ programming. The Scorpios afternoon (Sunday afternoon especially) sees the highest-cited Mykonos sunset crowd; book 2-4 weeks ahead for sun-bed access. Dress code is glamorous-casual: linen, silk, statement jewelry, leather sandals, no athletic shorts. Skip if you want a quieter beach experience; Scorpios is documented as a see-and-be-seen scene.
Mykonos is the party-island beach destination — south-coast beach clubs (Scorpios, Nammos, Paradise) + Mykonos Town (Chora) nightlife (Paradise Club, Cavo Paradiso for sunrise sets) + LGBTQ+ historic capital (Mykonos has been a Greek-island gay summer destination since the 1960s — Lola Bar, Babylon, Jackie O' are most-cited). Santorini is the cliff-village photogenic destination — Caldera-rim Oia and Fira are the most-photographed Greek-islands locations. Both share the same Aegean palette, meltemi wind, leather-sandal-and-linen register; Mykonos accepts more print/color, Santorini holds white-and-blue minimalism.
