How heatwaves can turn into wildfire season

This year’s June heatwave has smashed records across Europe, and wildfire warnings have followed in its wake. This is no coincidence. Heatwaves help create the perfect conditions for wildfires to ignite and spread. Here’s how it works:

1. Heatwaves suck moisture out of vegetation
Grass, shrubs and forest litter contain moisture, which helps stop sparks from turning into a fire. Prolonged high temperatures accelerate evaporation from soil and plants. This dry vegetation ignites and spreads faster and burns hotter.

2. Heatwaves bring dangerous winds
Heatwaves carry hot, gusting winds that turn small fires into larger, fast-moving ones. These winds supply fires with oxygen and carry embers ahead of the main front, which help the fire ‘jump’ over roads, rivers and firebreaks.

3. The effects stack up over time
The risk builds up as each day of heat and low humidity further dries out vegetation that hasn’t had a chance to recover. The AlertSat portal actually quantifies this growing wildfire vulnerability through a risk index score that measures cumulative dryness.

4. Why this matters more each year
Europe is warming faster than the global average. Long, intense heatwaves are now a regular feature of the summer. That means the conditions that turn a spark into a wildfire are showing up more often, in places that aren’t used to planning for them.

The solution: Early detection through the AlertSat portal
As wildfires grow more frequent and severe, early detection is the best way to limit the damage. To this end, the AlertSat portal uses satellite data and AI to detect wildfires and deliver rapid alerts straight to user workflows, cost-effectively and at scale.
