On April 1, 2026, the Greek island of Crete was hit by a powerful sandstorm that originated in North Africa and was intensified by Cyclone Erminio. The sky over the region took on an unusual orange-red hue, and dust concentrations in the air reached dangerous levels.

The storm caused widespread disruptions to infrastructure: power outages occurred, air travel was disrupted, and traffic accidents increased on the roads. A red alert has been issued in some areas, and authorities and emergency services are urging residents and tourists to exercise extreme caution.

What Happened in Crete: A Sandstorm, a “Red” Sky, and Critical Dust Levels

On April 1, 2026, Crete was engulfed by a massive cloud of African dust, which radically altered the island’s appearance and created dangerous living conditions. The sky over the region turned orange-red, and visibility deteriorated sharply.

According to the National Observatory of Athens, dust concentrations in the city of Rethymno exceeded 1,000 μg/m³, which is dozens of times higher than normal. Such levels are hazardous to health, especially for people with respiratory conditions.

Local residents and the media describe the situation as “Martian”—the island’s familiar landscapes have literally vanished behind a thick veil of dust. The cause of this phenomenon was a strong southerly wind that carried dust from North Africa, as well as Cyclone Erminio, which brought additional rain and storm gusts.

The storm did not affect only Crete. Similar conditions were observed on other Greek islands, including Naxos, Santorini, Tinos, and Syros, where heavy rainfall and storms compounded the dust.

Power outages and flight disruptions: how the storm paralyzed infrastructure

The storm dealt a serious blow to the island’s key infrastructure—the power grid and air travel were hit hardest. Due to the combination of dust, strong winds, and rain, the situation quickly became critical.

The biggest problems arose in the Heraklion area. Due to extensive damage to the power grid, a significant part of the region was left without electricity. Dust and strong gusts of wind caused power lines to snap, leading to widespread power outages.

Serious disruptions were also reported at airports. At Heraklion International Airport, visibility on the runway dropped to a critical 1,000 meters, making it impossible to land aircraft normally. As a result, 7 flights were canceled, and another 12 were diverted to other cities, including Athens, Corfu, and Chania.

In fact, not a single plane was able to land in Heraklion throughout the day.

In addition, dangerous conditions developed on the roads. Due to poor visibility, a traffic accident occurred in the Heraklion area—a female motorcyclist was injured and hospitalized. Isolated tornadoes were also reported in the Messara region: one of them even overturned a truck.

Due to the widespread impact of the severe weather, a red alert has been issued for parts of the island, and emergency services are urging people to avoid unnecessary travel.

Health risks and what tourists should keep in mind

The sandstorm has caused not only transportation and infrastructure problems but also a serious health threat. Due to the extremely high concentration of dust, air quality in Crete has deteriorated sharply.

Emergency services warn that these conditions are particularly dangerous for people with asthma, allergies, chronic lung diseases, as well as for children and the elderly. Even healthy people may experience symptoms—eye irritation, coughing, difficulty breathing, and a general feeling of malaise.

The situation is complicated by the fact that dust remains in the air for a long time and, combined with strong winds, spreads rapidly across the entire island. That is why authorities have implemented additional safety measures, including the temporary closure of schools.

Tourists and local residents are advised to:

1. Limit time spent outdoors

2. Keep windows closed

3. Use protective masks or respirators

4. Avoid non-essential travel

5. Monitor official warnings

According to meteorologists’ forecasts, the situation may remain difficult for several more days. It is expected that dust levels will begin to gradually decrease only after the wind direction changes.
