Mediterranean: hot dry summers (July-August can reach 35-40ยฐC on the mainland and at archaeological sites), mild coastal winters, colder in the north. The best time is the shoulder season โ late May-June and September-October โ with pleasant heat, warm sea and fewer crowds. In summer the Cyclades get the meltemi, the north wind that cools things down but can stir up the sea and delay ferries.

Euro (EUR). Cards and contactless are accepted almost everywhere and ATMs are common in towns, but on the islands and in country tavernas always keep some cash: some kiosks, local ferries and rental shops prefer it.
Modern Greek (with its own alphabet: knowing a few letters helps with signs). English is spoken very well in tourist areas; a 'kalimรฉra' in the morning is always appreciated.
EU citizens only need a valid ID card or passport: no visa, it's the EU/Schengen area. Travellers from many other countries enter Schengen visa-free for up to 90 days but should check their own nationality's rules. Note: Greek border police are strict and may refuse entry with an expired or damaged document โ make sure yours is intact, especially if you plan trips to non-Schengen countries (e.g. Albania). Always carry a copy of your document.
No mandatory vaccines. West Nile Virus (mosquito-borne) is now endemic from summer to autumn: use repellent in the evening. EU citizens can use the EHIC for public healthcare, BUT islands and tourist spots often lack hospitals for serious cases: travel insurance with cover for air transfer or repatriation is strongly recommended. Pharmacies are plentiful but work on a rota.
With an EU SIM, roaming is included at no extra cost. Visitors from outside the EU should get a local SIM or eSIM. 4G/5G is excellent in cities and on the larger islands; gaps in the mainland's interior valleys and on the smallest islands. Wi-Fi is widespread in hotels and tavernas.
230V, 50Hz, type C/F (Schuko) sockets โ standard European. Travellers from the UK, US and elsewhere need an adapter. Note: Santorini and some smaller islands can have brief power cuts in summer.
Eastern European Time: UTC+2 in winter, UTC+3 in summer (one hour ahead of Central European Time).
Cards and contactless are widely accepted, even for small amounts. Mild capital controls remain for Greek residents but do not affect tourists paying or withdrawing with foreign cards. On the islands, though, cash stays handy for kiosks, small tavernas and local ferry tickets.
๐ก Greece is at its best in the shoulder season (June and September): the right heat, a sea already or still warm, sites and islands without the August crush. And remember the travellers' golden rule: book your ferries on Ferryhopper as soon as you have your dates, and budget half a day of travel for each island. The crossing is part of the journey too.
