Hello. Another alternative in August is to go to Cantabria. There, you're near the beach as well as the mountains and it's cooler than in Madrid.

I was thinking about Cantabria too. Also Asturias. You must be right. If the heat becomes unstandable in Madrid, I'll run away to Santander. Muchas gracias for advice!

The forecast I have seen for Madrid tomorrow (6/27) calls for 102F!

Yes Mongo, and it got there too! Same for today and this week with highs around 40C!

I live in Cincinnati Ohio.

Those temps sounds crazy to me.
