Santorini in May runs Aegean pre-peak resort spring. Hellenic National Meteorological Service (HNMS) data put afternoon highs at 24°C / 75°F and overnight lows at 16°C / 61°F with 3 rain days. The volcanic-island geography (Santorini is the caldera rim of an ancient supervolcano, last major eruption ~1600 BCE) creates intense UV reflection off the white limestone-and-pumice cliffs and the Aegean. UV index 9-10 (very high). The dressing register is Greek-islands resort: lightweight cotton or linen in the Aegean palette (white, sky blue, sand, terracotta, occasional sage), slip-on leather sandals (Ancient Greek Sandals founded Athens 2012 is the most-recognized contemporary heritage; ELINA LEBESSI for upmarket; local Santorini sandal-makers in Fira and Oia), wide-brim sun hat, polarized sunglasses, swim cover-up, light cardigan for cool evenings. The Oia (the sunset village on the northern caldera rim), Fira (the capital), Imerovigli, Pyrgos, Akrotiri (the archaeological site), and Red Beach all reward the same lightweight-cotton-and-leather-sandal approach. Greek heritage brands: Ilias LALAoUNIS jewelry, Themis Z (Athens-founded contemporary), Linum (Greek textile), Anastasios Sotiropulos for upmarket. Cliff-edge stilettos are a documented Santorini visitor injury class — flat sandals or wedges for sunset.
Santorini May is the pre-peak resort spring — Oia sunset crowd starting to thicken, the Caldera-side hotels opening pools for the season, the Aegean reflection sharper than at any latitude in the Mediterranean. The dressing register holds firm: white linen, blue-and-white print, slip-on leather sandals.
The capsule

Frequently asked questions
Per the Hellenic National Meteorological Service (HNMS): average daily high 24°C (75°F), low 16°C (61°F), 3 rain days totalling 12mm. Pre-peak Aegean spring; the meltemi wind (the strong northerly summer wind) starts ramping in late May. UV index 9-10 (very high) — caldera-cliff and Aegean reflection doubles exposure. Daylight 14 hours. Sea temperature 18-19°C / 64-66°F (still chilly for swimming; warmest in August).
Oia (the northernmost cliff village) is the most-cited Santorini sunset spot — sunset visible from the Byzantine Castle ruins (Kasteli) at the northern tip, the village pedestrian street, and most restaurant balconies. Crowds peak 30-45 minutes before sunset (7:30pm in May). Alternative spots with thinner crowds: Imerovigli (between Fira and Oia, with the same caldera-rim view), Pyrgos (the highest village inland, with a different angle), Akrotiri lighthouse (the southernmost point). Pack: cotton dress, slip-on sandals (Oia stones are uneven), light cardigan for cool wind, polarized sunglasses, sun hat. Skip stilettos — Oia cobble + crowds = documented injury.
Ancient Greek Sandals (Athens-founded 2012, the most-recognized contemporary Greek heritage; multiple Santorini boutiques in Fira and Oia); Ilias LALAoUNIS (Athens jewelry since 1968, museum-curated heritage); Themis Z (Athens contemporary, modern Greek-print resort wear); Linum (Greek heritage textiles, traditional weaving); Zeus+Δione (Athens contemporary); local Santorini sandal-makers in Fira and Oia (made-to-measure leather sandals, ~€80-120). Skip the mass-market 'I love Santorini' tee shops; the contemporary Greek register is in the boutique-and-jewelry vocabulary.

ATV rental: ~€30-50/day; scooter ~€20-30/day; car ~€40-80/day. International driving permit recommended. Skip ATVs for cliff-edge Oia traffic (parking is impossible); walk or take the public bus. Pack: light cotton, slip-on sandals or sneakers (ATVs require closed-toe), wide-brim sun hat, sunglasses, SPF 50, polarized sunglasses.
