June - July
High season begins in early June for most of the country except for the northwest and the central parts of the country, which will still be in the shoulder season for a few weeks. The entire country will be in the high season by the beginning of July. Accommodations will become booked far in advance, so be sure to choose your ideal hotel far enough in advance to book it. Prices will increase for accommodations up to 50% in many locations since it is the high season. Lines can be seen at many popular attractions across the country; it is advised to either arrive at the beginning or end of the day if there is a point of interest you really must see.
Dry conditions will be seen across the country, although the south will become more humid as June turns into July. Highs in Bilbao will average in the mid-70s, with lows in the upper 50s to around 60. Barcelona will warm into the mid and upper 80s, with lows in the mid-60s to around 70. Madrid`s average highs will be in the 80s to near 90, with lows in the low to mid 60s. Valencia`s highs average in the low 80s in June and mid-80s in July, with lows in the upper 60s to near 70. Seville`s highs will start out in the 80s and will rise rapidly to the upper 90s by July, with lows in the 60s. Gran Canaria`s highs will be in the upper 60s and low 70s with lows around 60. Temperatures can, and many times do, become hotter than what is outlined, so be prepared for very warm weather in many locales.
