Which outdoor places deserve a closer look on hot days?

01How do I read this map?

Compare the warm-coloured patches with land cover. Use the contrast to discuss shade and outdoor places people use, then check conditions on the ground.

  1. Orange and red patches follow built-up and open land-cover classes, with invented warmer values than forest and water.

  2. The legend is relative: “Higher” is a display category, not degrees Celsius, a comfort threshold or measured human heat exposure.

  3. Transparent forest areas are not proven cool or safe. Conditions change with weather, shade, time of day and the activities people undertake.

Illustrative colours, not measured temperatures. Blank areas do not establish absence of risk.

02What does this indicator mean?

Surface temperature describes how warm the ground, roofs or vegetation are. Air temperature describes the surrounding air. Perceived-temperature indicators also account for factors such as humidity, wind and radiation. A heatwave describes sustained unusually hot conditions over time; a single surface map cannot establish one.

03What evidence is available here?

Real context

ESA WorldCover classifies the landscape in 2021 at about 10 m. Tree cover and built-up land provide context, but do not describe current street-level shade or temperature.

Simulated overlay

The heat illustration applies invented weights to land cover and smooths the result. It contains no satellite thermal observations, air-temperature measurements or perceived-temperature calculation.

The study window is approximately 10 km across, not an authoritative village boundary. Dates and resolution differ between datasets.

04How can we use it locally?

For community activities

Discuss where people walk, wait, work or gather outdoors. Compare shaded and exposed settings during a site visit, including how their use changes through the day.

For agencies and planners

Use the discussion to select monitoring sites and investigate shade or vegetation opportunities. Account for access, land ownership and maintenance before choosing interventions.

Take these questions to a local discussion

  • Which walking routes, waiting areas and gathering places feel most exposed?
  • When are these places used, and does usable shade move during the day?
  • Has tree cover or development changed since the 2021 source map?

05What should happen next?

  1. Explore and record

    Map the outdoor places and routes residents actually use, with permission for any community records.

  2. Check the evidence

    Collect dated shade observations and comparable temperature measurements with a documented method and weather conditions.

  3. Discuss suitable actions

    Discuss options such as shade structures or tree planting at verified priority sites. Evaluate their suitability and effectiveness locally.

06What can’t we conclude?

The overlay cannot identify heatwaves, report a temperature, diagnose health risk or show indoor conditions. Surface heat and perceived heat are not interchangeable. No local ranking of the hottest places has been established.

For current conditions and emergency decisions, use official agency advice. This guide does not replace a local assessment.
