Living in Arroyomolinos

Arroyomolinos is a small town of 38,075 inhabitants inland in Madrid, with cold winters and very hot summers (January nights 1.9°C, August afternoons 33.1°C). Public waiting lists in Madrid are among the shortest in Spain (50 days for planned surgery). Madrid is 0 h 14 min away by train. Summer air is dry (August dew point 10.5°C), so the heat is easier to bear than on the coast. Against that, the centre is thin on everyday shops and services (2 of 6 essentials within a 10-minute walk); winter nights are cold (1.9°C in January, 29 frost nights a year); summers are hot (33.1°C on an average August afternoon, 27 days of 35 °C or more a year). Around 2055, Spain's official climate scenarios put August afternoons here at about 34.2°C and the number of warm nights at 40 a year.

Each sentence is chosen by where the town ranks among the 333 places compared on that measure (top or bottom 20%); the numbers are the ones in the sections below, from the sources named there.

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

Water

Reservoirs now

54.9% full (week of 2026-09-29); the same week in the previous 10 years averaged 47.0%

Worst week 2016-2025

34.4% full (2019-10-15)

Weeks below 40% full, 2016-2025

9% 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.

Dew point measures how sticky the air feels: under 13 °C (55 °F) feels dry, 16-18 °C (61-64 °F) muggy, over 18 °C oppressive. For comparison, Davis, California (also Köppen Csa) has a summer dew point of about 11 °C. "Typical hottest day" is the 1991-2020 average of each year's single hottest day. Estimates are counted from daily satellite data adjusted to this place's averages; checked against AEMET's own 30 °C counts they are usually within 4 days a year.
