What stands out

What we found in Majadahonda

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

1

1.421 homes at very high wildfire risk

463 buildings

These are 463 buildings right next to vegetation that can burn. Of these, 13 are blocks of flats with 930 homes, where evacuation is harder.

  • Calle de Isaac Albéniz: 450
  • Avenida de la Oliva: 220
  • Avenida Rey Juan Carlos I: 193
  • Calle Moreras: 45

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

From 11 to 50 tropical nights a year

11→50 nights

In a typical building in Majadahonda, nights when the temperature stays at or above 20 °C would rise from 11 a year (1991-2020) to about 50 by 2050. For this reason, 100 % of homes would be at a high or very high level.

Median of the buildings. Intermediate-to-high emissions scenario (SSP3-7.0).

3

Where there are fewer trees, 3,7 °C hotter

3,7 °C

Around homes with less than 2 % tree cover, the surface in summer is 2,4 °C above the median for Majadahonda; with more than 40 % tree cover, 1,3 °C below. 1.135 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.

20 schools in heat islands

20 of 39

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 20 schools with the hottest surroundings.
  • 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.
  • 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.
