Living in Sant Joan Despí
Sant Joan Despí is a small town of 35,926 inhabitants 9 km from the sea in Barcelona (Catalonia), with cool winters and warm summers (January nights 5.4°C, August afternoons 28.8°C). The nearest international school (St. Patrick'S International School, international curriculum) is 0.1 km away. Year-round direct flights to Amsterdam, London, Brussels, Paris and the US leave from Josep Tarradellas Barcelona-El Prat Airport (BCN), 8 km away. There is a public general hospital in town (Hospital de Sant Joan Despi Moisés Broggi, 328 beds). Against that, housing is expensive (3,445 €/m² appraised, 804 € a month for a typical apartment); August is humid (dew point 19.2°C), so the heat feels sticky; public waiting lists in Catalonia are long (142 days on average for planned surgery). Around 2055, Spain's official climate scenarios put August afternoons here at about 29.9°C and the number of warm nights at 72 a year.

Counted in OpenStreetMap within 800 m of the town centre, taken as the point OpenStreetMap marks as the town's centre, moved at most 500 m to the busiest nearby spot (for a few spread-out municipalities without such a point: the busiest spot near the official coordinate). OpenStreetMap is kept by volunteers: very complete in most Spanish towns, thinner in some. “Everyday essentials” only asks whether the basics are there, so a small town can score 6 of 6; “lively centre” ranks each count among all 333 places and averages them, so it mostly reflects size. Large municipalities with several centres (Lorca, Oleiros, Ames…) can score low because their official centre is a small village.
Holiday lets and beaches
- Tourist apartments
- 12 (0.09% of all homes; Spain 1.28%), 0.1 tourist beds per 100 residents (May 2026)
- Blue Flag beaches

Tourist apartments: INE count of homes listed on Airbnb, Booking and Vrbo. A high share means busy summers and pressure on rents.

Water
- River basin
- Cuencas Internas De Cataluña
- Reservoirs now
- 73.6% full (week of 2026-09-29); the same week in the previous 10 years averaged 57.5%
- Worst week 2016-2025
- 14.5% full (2024-03-05)
- Weeks below 40% full, 2016-2025
- 26% of all weeks
Ministry for the Ecological Transition, weekly hydrological bulletin: all reservoirs over 5 hm³ in the basin. Low reservoirs are what led to drought restrictions in Catalonia (2023-24) and Andalusia (2022-24). Some basins (Segura) also rely on transfers and desalination, so their reservoir level alone overstates the risk of taps running dry.
