AyamonteClimate risk in its neighbourhoods, streets and rivers, today and in 2050

We have scored the climate risk of the 4.685 buildings in Ayamonte using Cadastre data, satellite imagery and climate projections, and added it up by area, street and watercourse. The clearest change comes at night: from 33 to 66 tropical nights a year by 2050.

What stands out

What we found in Ayamonte

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

1

1.117 homes at very high wildfire risk

254 buildings

These are 254 buildings right next to vegetation that can burn. Of these, 4 are blocks of flats with 772 homes, where evacuation is harder.

  • Calle López de Rueda: 373
  • Avenida de los Cisnes: 224
  • Paseo Marítimo: 175

Proximity to woodland and to burnt areas (ESA WorldCover, EFFIS). It does not measure the state of the vegetation or any firebreaks.

From 33 to 66 tropical nights a year

33→66 nights

In a typical building in Ayamonte, nights when the temperature stays at or above 20 °C would rise from 33 a year (1991-2020) to about 66 by 2050. For this reason, 100 % of homes would be at a high or very high level.

868 homes less than 2 m above sea level

868 homes

That is 5 % of homes. The extreme sea level in a 100-year storm reaches 2,39 m today and 2,63 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.

4

158 homes in a flood zone

158 homes

They are in the area that can flood once every 500 years according to the official maps (SNCZI); 154 of them are in the 100-year area. Next to Caño de la Mojarra, 1 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.

5 schools in heat islands

5 of 8

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 5 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.
  • Firebreaks and evacuation routes in the streets that border woodland.
  • 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.
  • Keep the strip around your house clear of dry vegetation and know both ways out of your street.
  • Look up your building: the free report gives its level for each hazard, and the Climate Note gives the full detail.
