Roquetas de MarClimate risk in its neighbourhoods, streets and rivers, today and in 2050

We have scored the climate risk of the 16.538 buildings in Roquetas de Mar using Cadastre data, satellite imagery and climate projections, and added it up by area, street and watercourse. The clearest change comes at night: from 84 to 114 tropical nights a year by 2050.

What stands out

What we found in Roquetas de Mar

It comes from matching each building with its neighbourhood, its street, the nearest watercourse and its surroundings.

1

2.009 homes in a flood zone

2.009 homes

They are in the area that can flood once every 500 years according to the official maps (SNCZI); 2.012 of them are in the 100-year area. Next to Rambla de Vícar, 504 homes are inside the flood zone, less than 100 m from the watercourse.

According to the Ministry’s studies, this is an annual probability of 0,2 % (500 years) or 1 % (100 years), not “once every 500 years”: it can happen two years in a row. Small gullies are not always mapped.

Where there are fewer trees, 4,0 °C hotter

4,0 °C

Around homes with less than 2 % tree cover, the surface in summer is 0,7 °C above the median for Roquetas de Mar; with more than 40 % tree cover, 3,3 °C below. 18.243 homes are in surroundings with almost no trees.

Ground surface temperature (Landsat), not air temperature. More trees usually go with less asphalt and lower density: this is a correlation, not a measure of the effect of planting trees.

From 84 to 114 tropical nights a year

84→114 nights

In a typical building in Roquetas de Mar, nights when the temperature stays at or above 20 °C would rise from 84 a year (1991-2020) to about 114 by 2050. For this reason, 100 % of homes would be at a high or very high level.

1.257 homes less than 2 m above sea level

1.257 homes

That is 2 % of homes. The extreme sea level in a 100-year storm reaches 0,84 m today and 1,14 m by 2050.

Ground elevation at the building (IGN digital terrain model). Being low-lying does not mean it will flood: that depends on the beach, sea defences and drainage.

10 schools in heat islands

10 of 32

Schools whose surroundings are at least 1 °C hotter than the municipal median in summer. They are the first candidates for shade and tree-lined playgrounds.

What can be done

For the town council and for residents

For the town council and its technical staff

  • Climate shelters, and late-afternoon and evening opening hours at libraries and community centres in the areas with the most tropical nights.
  • Shade and trees in the playgrounds of the 10 schools with the hottest surroundings.
  • Review with the river basin authority the watercourses with no official mapping that run next to homes, and keep them clear.
  • Emergency self-protection plans in the schools, care homes and health centres that are in a flood zone.
  • Download the tables by area, neighbourhood, street and watercourse (Data tab) to cross-check them with urban planning.

For residents

  • Air your home in the early hours, shade west-facing walls from the sun and ask about grants to insulate the roof.
  • If you live on a ground floor or have a garage next to a watercourse, have a plan: where to go upstairs, what to switch off and how to hear about warnings.
  • Look up your building: the free report gives its level for each hazard, and the Climate Note gives the full detail.
