August - September
August is the final month of the high season for most of the country, except for Andalusia, where the warmer temperatures will extend the high season into September. By the middle of September, children across Spain will be back in school, meaning most Spanish families will not be vacationing and adding to queues at sights across the country. By the end of September you should notice fewer crowds at many attractions. Some coastal destinations in the north of the country may wind down operations for the season at the end of September. By the end of September, the entire country transitions to the shoulder season, and prices on hotels and other accommodations will begin to retreat from their summer peaks.
Bilbao`s highs will average in the mid to upper 70s with lows in the upper 50s to around 60. Barcelona`s temperatures will rise to the 80s during the day and fall into the 60s to near 70 at night. Madrid`s highs will be close to 90 in early August, but will retreat to the upper 70s by late September. Lows will be in the low to mid 60s. Valencia`s highs will be in the mid-80s and lows will be in the upper 60s to around 70. Highs in Seville will still be in the low to mid 90s, and low temperatures will fall to the mid-60s. Gran Canaria`s weather should stay constant with highs in the low 70s and lows in the low 60s.
