Checking the weather in Catania or Taormina is useless if your destination is the volcano. Etna creates its own microclimate. There may be bright sunshine on the coast and a snowstorm in Piano Provenzana. Knowing where to look for the right forecast can save your trip.
Forecast Reliability
Generic weather apps on your phone often get the altitude wrong, showing you temperatures of Etna villages (700m) instead of those of the craters (3000m or 2500m). There is a huge temperature difference, often more than 10-15 degrees.
The most reliable site for hikers is 'Mountain Forecast'. This portal allows you to select the exact altitude for the forecast. Always look at data for 2000m (Rifugio Sapienza/Piano Provenzana) and 3000m (Summit Craters).
The Wind Factor: The Real Enemy
More than rain or cold, the number one enemy on Etna is the wind. Gusts exceeding 30-40 km/h can make the excursion unpleasant and dangerous, lifting volcanic dust that gets into your eyes and making it difficult to walk on the ridge.
Furthermore, the Etna Cable Car closes for safety reasons if the wind exceeds certain limits. If you planned to go up by cable car, always check the wind forecast. If strong wind is expected, it is very likely that the facilities will remain closed.
Webcams: The Eye in Real Time
Forecasts are useful, but reality is better. Before leaving, always take a look at the live webcams of the INGV (National Institute of Geophysics and Volcanology). They show the situation in real time at the summit craters and in the parking lots.
If you see thick fog covering everything from the cameras, consider whether it is worth going up. Sometimes the fog is just a passing bank, but other times it 'sticks' to the mountain for days. Volcanological guides know how to interpret these signs better than anyone else.
The Slope Fog Phenomenon
On Etna there is a typical phenomenon: afternoon fog. Often in the morning the sky is clear, but around 12:00-13:00, the humidity rising from the sea condenses meeting the cold air of the volcano, creating a 'hat' of clouds covering the top.
For this reason, guides always recommend leaving early in the morning. The early bird catches the worm, and on Etna sees the view!
Reading the INGV Bulletin
For the more technical, the INGV website of Catania publishes weekly bulletins on the state of the volcano. It does not only speak of atmospheric weather, but of 'volcanic weather'.
Learning to read terms like 'volcanic tremor' can be fascinating. If the tremor is high, it means that the magma is moving energetically in the conduits: there is a possibility of Strombolian activity (explosions) or lava fountains. If the tremor is low, the giant is sleeping.
Recommended Smartphone Apps
In addition to Mountain Forecast, download 'Windy'. It is a visual app showing air currents. If you see that the wind vectors on Etna are purple or red, stay home or choose a low-altitude forest trail.
Another useful app is 'Etna Sci' (in winter) which gives real-time opening of facilities and snow conditions.
Why Choose It
- Check Mountain Forecast for the correct altitude
- Check wind speed (>30km/h risk of cable car closure)
- Watch INGV webcams before going out
- Don't trust the weather on the coast
- Fog can arrive in a few minutes
