The Spain Herald is on vacation for August, since we're more of a political news website than anything else, and both Madrid and Brussels close down for August so that everyone can pack the beaches and sweat like hell on the dirty sand while paying exorbitant prices.
Recommendation: Find a small town as far away from the Mediterranean as possible and go there. Try Galicia or Leon or Navarra or Huesca. Don't come to Barcelona. It's packed, and I mean packed. Downtown is so full of tourists you can barely move. There's no way you'll find anywhere to stay. Half the places of business are closed and the rest are tourist traps. Come to Barcelona in mid-October or so when things are much more relaxed.
