Portugal is known for its perfect beaches for surfing, its fantastic food, its cultural heritage… and, unfortunately, also for its wildfires during summer season. We experienced hundreds of wildfires when we visited Portugal two years ago. We remember ourselves crossing black smoke, having fire on the road margins, smelling smoke all day and wondering how far was the fire. One of the worst days was the one we spent in Porto. It was almost impossible to breath and it was raining ash as if a volcano erupted close to us.
