Between May 21 and 31, 2026, France went through an unprecedented heatwave for the time of year, breaking hundreds of records across the country. Heatpeaks is a 3D visualization of that event, built from real weather station data.
The project maps temperature anomalies recorded by Météo-France ground stations against 1991-2020 climatological normals. Rather than picking a single day, a composite temporal maximum was computed across the peak heat period (May 24-28) to capture the full extent of the event as it moved across the country.
Raw observations from 62 stations were collected through the Météo-France tabular API on data.gouv.fr, cleaned and processed in Python (pandas, scipy), then spatially interpolated to produce a continuous surface. The resulting heightmap was rendered in Blender as a 3D relief where elevation represents temperature anomaly intensity.
