AEMET Eclipse Forecast: Cloud Cover Map for August 12 2026

AEMET has released its definitive forecast for the solar eclipse on August 12, and the outlook is mostly favorable for skywatchers across Spain. The latest update to the special meteorological bulletin shows largely clear skies over most of the country, but three areas may see cloud cover that could hinder visibility.

The eclipse, which will be total along a narrow path across Spain, is a highly anticipated event. AEMET's forecast is crucial for planning viewing locations, and the good news is that the majority of the country should have excellent conditions.

Where Clouds May Interfere with the Eclipse

According to AEMET, the main areas of concern are the Cantabrian coast, parts of the Galician coast, and the Alborán Sea region. These areas are expected to have predominantly cloudy skies during the day.

Unfortunately, two of these regions lie within the path of totality, meaning some viewers in those spots may miss the full effect. The third area, the Alborán Sea, is outside the totality zone but could still see partial obstruction.

Specific Regions to Watch

During the day on August 12, stability is forecast for most of Spain, with little cloud or clear skies. However, the Cantabrian area and parts of the Galician coast and the Alborán Sea will see cloudier conditions.

Additionally, as the day progresses, convective clouds may develop over mountains in the north and the eastern third of the peninsula, potentially leading to isolated showers or thunderstorms. In the Canary Islands, clouds are also expected, but the timing of the eclipse may spare some areas.

Timing of Cloud Cover

Just around the time of the eclipse, most of the cloudiness will be concentrated in the Galician and Cantabrian coasts and parts of eastern Andalusia. This is critical because the eclipse will occur in the late afternoon or early evening, depending on location.

The good news is that the forecast has not changed much since the first bulletin on Friday. The height of the clouds is also a factor: the map shows fewer low and medium clouds and more high clouds, which are less likely to obstruct the view.

Understanding the Cloud Height Factor

High clouds are thinner and allow more sunlight to pass through, so even if they are present, the eclipse may still be visible. Low and medium clouds are thicker and can completely block the view.

This distinction is important for eclipse viewers: if you are in an area with high clouds, you may still get a good view, but if low clouds dominate, your chances are reduced.

Key Takeaways for Eclipse Viewers

• Most of Spain will have clear or mostly clear skies during the eclipse.
• The main risk areas are the Cantabrian coast, Galician coast, and Alborán Sea.
• Two of these areas are within the path of totality, so viewers there should have a backup plan.
• High clouds are less obstructive than low clouds, so some cloudy areas may still offer a view.
• Check local forecasts closer to the event, as conditions can change.
