Thessaloniki

Good for a Greek regional capital, a notch below Athens for the rarest cases. Major public/teaching hospitals include AHEPA University General Hospital (~680 beds, full specialties) and the highly regarded Papageorgiou General Hospital (~800 beds, internationally rated among Europe's better institutions), plus Hippokration and G. Papanikolaou. Private options — Interbalkan Medical Center and Euromedica — serve expats with English-speaking staff and international standards; many doctors speak English. Public ESY care is cheap but can mean waits and uneven facilities, so most foreign retirees carry private insurance. The very most complex care may still route to Athens.

Mediterranean but in a transitional zone, so more seasonal than the islands. Summers are hot and fairly humid (highs ~30-33C/86-91F, heatwaves above 35C/95F); winters are cool, damp and grey with daytime ~9-13C/48-55F and nights near 0-4C/32-39F. Its seaside, lakes-adjacent position brings high year-round humidity and notable winter fog. Rain concentrates Nov-Feb; July-Aug are dry.

Reasonably safe but the most street-crime-prone of these four. Numbeo's Crime Index sits around 52 (moderate) with a Safety Index near 48 — higher than Lisbon or small-town Greece. Violent crime against foreigners is rare; the real issues are pickpocketing and minor scams in crowds (Aristotelous Square, buses, near landmarks). The Vardaris district and the area around the train station have drug/prostitution activity and feel unsafe at night, especially for women, and western/industrial fringes report more petty crime. Stick to the waterfront promenade, Aristotelous, Ladadika and the upper town and it feels lively and comfortable; Greece overall is US State Dept Level 1.

English goes a long way thanks to a young, university-heavy population — Aristotle University alone has ~70,000 students — plus English signage, menus and long-established American institutions (Anatolia College, Pinewood, ACT). The foreign community (British, German, French, American, Balkan) is growing, with active 'Expats in Thessaloniki' groups, but it's smaller and less retiree-centric than Athens or the islands. It's an authentic working Greek city, so some everyday Greek still helps.

No nonstop service between Thessaloniki (SKG) and the US — every trip connects. Common routings run through European hubs: Munich/Frankfurt (Lufthansa), Zurich (Swiss), Istanbul (Turkish), Vienna, Amsterdam or Paris, then a ~9-11h transatlantic leg. Athens (frequent ~1h hop) is another connection point. Realistically budget 14-18h door-to-door to the US East Coast; West Coast is longer.

Greece offers a flagship incentive for new retirees: a flat 7% tax on ALL foreign-source income (pensions, dividends, withdrawals) for up to 15 years, provided you become a Greek tax resident (183+ days), weren't Greek-tax-resident in 5 of the prior 6 years, and move from a treaty country (the US qualifies). Apply by Mar 31 for that tax year. Without that regime, Greece taxes residents' worldwide income progressively (9% up to 44%). US citizens still file in the US; the US-Greece treaty and foreign tax credits limit double taxation, and a US-Greece totalization agreement covers Social Security.
