How to Check Cloud Cover for the August 12 Solar Eclipse 2026

If you're planning to watch the August 12 solar eclipse, knowing whether clouds will spoil the view is crucial. In this guide, we'll show you how to check cloud cover forecasts using AEMET's official map and reliable weather apps, so you can avoid disappointment.

Why Cloud Cover Matters for the Solar Eclipse

A solar eclipse is a rare and spectacular event, but clouds can completely ruin the experience. Even a thin layer of clouds can obscure the sun's corona during totality, turning a once-in-a-lifetime moment into a frustrating letdown. That's why checking the cloud cover forecast is essential, especially if you're traveling to a specific location for the event.

How Reliable Are Cloud Cover Forecasts?

According to AEMET (the Spanish Meteorological Agency), cloud cover predictions are only reliable up to about five days before the event. Within that window, forecasts are quite accurate, but beyond five days, conditions can change significantly. Since the eclipse is just a couple of days away, any forecast you check now is likely to be dependable. However, if you looked at the weather a week ago, it's worth rechecking.

Using AEMET's Official Map for Cloud Cover

AEMET provides an official map that shows the latest cloud cover predictions for Spain. This tool is invaluable for planning your eclipse-viewing location. The map is updated regularly, so you can see the most current forecast for your area. To use it, simply visit AEMET's website and navigate to the cloud cover section. The map uses color-coding to indicate cloud density, making it easy to identify clear skies. The background to this story is set out in Solar Eclipse in Cornwall: A Magical Communal Experience.
