High season in Spain generally means Christmas, New Year, Easter and roughly June to September. The applicability of seasonal fares varies depending on the specific destination. You may find reasonably priced flights to Madrid from elsewhere in Europe in August, for example, because it is stinking hot and everyone else has fled to the mountains or the sea. As a general rule, November to March (aside from Christmas and New Year) is when airfares to Spain are likely to be at their lowest, and the intervening months can be considered shoulder periods.
