Brush up on your Spanish (or Catalan). With data from more than 2,000 weather stations dating back to the 1950s, the Climatic Atlas of the Iberian Peninsula provides temperature means, minimums, and maximums as well as precipitation and solar radiation for each month of the year. This fine looking mapping site is a creation of the Autonomous University of Barcelona and was just released last month.
