Greece's wildfire risk rises as low vegetation and rare polar meltemi winds intensify fires

Greek wildfires polarized meltemi low vegetation fire risk alert EU firefighting resources

Scientists say the surge in low‑lying vegetation after winter and spring rainfalls acted as a hidden fuel source for the 2024‑2026 Greek wildfires, while the continued presence of combustible material in unmanaged forest areas remains a core problem for fire spread.

A rare “polarized meltemi” wind episode in late July 2026 produced gusts over 72 km/h and persisted for several days, greatly increasing the speed and reach of the fires and grounding firefighting aircraft.

On 7 August 2026 Greek authorities issued a fire‑risk alert covering 28 regions—including Attica, the Aegean islands and parts of the mainland—citing high temperatures, prolonged drought and strong northerly winds. The European Union has activated its RescEU stock of firefighting aircraft and helicopters, and the European Forest Fire Information System (EFFIS) reports more than 434 000 ha burned since early 2026.

[● 2 SOURCES] The same low‑vegetation and land‑management issues are observed in recent large fires in Spain and France. (Professor Apostolos Voulgarakis)
[● 2 SOURCES] Increased low vegetation caused by winter and spring rainfalls acted as a hidden factor for the 2024 wildfires in Greece. (2024)
[● 2 SOURCES] Continuation of combustible material is a common characteristic of recent large fires in Greece. (Professor Apostolos Voulgarakis)
[○ 1 SOURCE] The main zone of action for strong winds is the Aegean Sea, not the mainland interior. (Meteorologist Olga Papavgoulli (ERT))
[● 2 SOURCES] Increased low vegetation resulted from rainfalls, not from drought conditions. (Professor Apostolos Voulgarakis)
[○ 1 SOURCE] High temperatures, low humidity and strong northeasterly winds over the Aegean Sea are maintaining an elevated fire‑danger level. (Meteorologist Olga Papavgoulli (ERT))
[● 2 SOURCES] Continuation of combustible material is a central problem for fire spread in Greece. (2024‑2026)
[● 2 SOURCES] Southern Crete, especially south Rethymno, faced high fire risk due to wet vegetation followed by heat and strong winds. (Professor Apostolos Voulgarakis)
[● 2 SOURCES] The polarized meltemi wind persisted for several consecutive days, heightening wildfire risk and grounding firefighting aircraft. (July 2026)
[○ 1 SOURCE] Meteorologist Olga Papavgoulli warned that the combination of high temperatures, low humidity and strong winds will favor rapid wildfire spread. (2026)
[○ 1 SOURCE] The EU’s RescEU programme provides a strategic stock of firefighting aircraft and helicopters for member states during severe fire events. (2026)
