Per HNMS: average daily high 29°C (84°F), low 22°C (72°F), 0 rain days. Peak Aegean summer; the meltemi wind moderates afternoon heat. UV index 11 (extreme) at midday. Sea temperature 23-24°C / 73-75°F (warming toward August's 25°C / 77°F peak). Daylight 14h 20m. Heat-wave events possible (Greek summer 2021 mainland 47°C / 117°F; Mykonos stays cooler with meltemi).
Cavo Paradiso (above Paradise Beach) is the most-cited Mykonos super-club — open since 1993, hosts world-class DJ programming throughout summer (Carl Cox, Solomun, Black Coffee). Sunrise sets are the signature; doors typically open at 1am, peak 4-7am, sunrise 6-7am. Dress code: glamorous-casual; resort dress, leather sandals, statement jewelry. Skip flip-flops, athletic shorts, branded streetwear. Tickets €40-100; book ahead through Cavo Paradiso website or Resident Advisor. Pack: lightweight cotton, leather sandals, light cardigan for cool 24°C / 75°F sunrise, water bottle, sunglasses for the morning glare.
Little Venice (Mykonos Town's western edge, the cliff-edge Venetian-era buildings — sunset 8:45pm in early July, 8:15pm by month-end) — the most-cited Mykonos sunset photo, shot from Caprice Bar or 180° Sunset Bar. Mykonos Windmills ridge (5 surviving 16th-century white-and-thatch windmills, walking distance from Little Venice) — the second-most-photographed Mykonos sunset angle. Scorpios Beach Club (Paraga, south coast) — the curated DJ-set sunset experience. Pack: cotton dress, slip-on leather sandals, sun hat with chin-tie, sunglasses, light cardigan for cool wind, polarized sunglasses (sunset glare on Aegean).
North-coast beaches run quieter than the south-coast beach clubs: Agios Sostis (small, untouched, Kiki's taverna for the most-cited grilled-fish lunch — no electricity, only wood-fired oven); Fokos Beach (remote, donkey-and-walking access, untouched by infrastructure); Lia Beach (south-east, smaller and quieter than Paradise/Super Paradise); Mersini Beach (north-east, secluded). Skip the south-coast 'Paradise/Super Paradise' beaches in July if you want quiet — those are at peak. Pack: swim, cotton cover-up, sandals, sun hat, sunglasses, SPF 50, water bottle, sun shelter (no umbrellas at remote beaches).
Skip beach-club lunches without reservations 2-4 weeks ahead. Don't underestimate pricing — Nammos lunch €150-500/person, Scorpios sun-bed €100-300/person, hotel rooms €600-3,000+/night peak. Skip ATVs in heavy meltemi (12-15 m/s wind can flip them). Skip ferries to Santorini or Athens in strong-meltemi days; check the morning forecast. Don't expect dinner before 9pm. Skip cliff-edge stilettos at Little Venice — meltemi crowds + cobble = injury risk. Pack the chin-tie sun hat and hair tie.
