Meteorologist links Crete’s Red Code wildfire alert to wind, heat and terrain
A combination of very dry fuel, strong winds, prolonged heat and terrain effects pushed Crete into a wildfire state of alert for Friday, August 28, meteorologist Thodoris Kolydas said.
According to Kolydas, Friday’s “Red Code” wildfire warning for Crete “is not simply due to ‘strong winds,’ but to the particularly unfavorable combination of very dry fuel, prolonged heat and, above all, an exceptionally intensified wind field.”
Civil Protection has placed the regional units of Rethymno, Heraklion and Lasithi in Category 5 — Alert Status, the top level of the five-tier risk scale, for Friday, Kolydas said. Chania is rated Category 4 — Very High Risk. Rhodes and Karpathos are also in Category 5, he added.
Wind gusts forecast up to 135 km/h
Forecast data from the ICON-EU model help explain why Crete stands out, Kolydas said. The model puts the maximum average wind speed at 10 meters locally at around 68 km/h, or 8 Beaufort, while gusts are forecast to be even more extreme — up to 135 km/h in eastern Crete and up to 126 km/h in the south of the island, according to the meteorologist.
Kolydas cautioned that these are the model’s maximum local forecast values, not wind speeds expected across the whole island, but said the distinction matters for fire-weather risk. “It’s one thing to have wind that can trigger a fire, and another to have wind that, once a fire starts, can make it extremely difficult to control,” he said.
With such a strong wind field, an initial fire could gain spread speed very quickly, generate spot fires well away from the main front, and significantly complicate both ground and aerial firefighting, Kolydas said.
Terrain adds to the risk
Crete’s terrain compounds the danger, according to Kolydas. He said the island’s pronounced relief can further accelerate wind flow in specific leeward areas, mountain passes and slopes, producing very strong, gusty local intensifications — which he said also explains the very high maximum gusts shown by the ICON-EU model.
Civil Protection itself has noted that prolonged heat has dried out fuel and that stronger winds significantly raise the risk of rapid fire spread, Kolydas said. He added that this is why Crete has also been placed under Red Code mobilization status, with increased operational readiness.
The meteorologist stressed that Friday’s “red” designation should not be read as a forecast that fires will actually break out. Rather, he said, it means that if ignition occurs — particularly in Rethymno, Heraklion or Lasithi — weather and fire-weather conditions could favor an extremely fast and potentially dangerous escalation. For that reason, he concluded, prevention and immediate response to any initial outbreak will be critical on Friday.
Crete had already been placed on very high wildfire risk a day earlier, with authorities elsewhere on the island moving to close forests, gorges and trails under the Red Code alert.
