Barcelona and Madrid
The verdict for August

Peak summer
+Hot and excellent for beach days.
–Peak summer conditions, high prices and heavy tourist demand.
A beach-first trip — the city itself is at its most crowded.

Peak heat and a noticeably slower city.
+Fewer locals + long evenings
–Extreme heat + some closures
August is Madrid’s hottest month and many locals leave the city for their own summer holidays. The result is a strange mix of intense heat, quieter streets and excellent late-night energy.
Scores and crowd levels are my own judgement; temperatures are monthly averages. Higher scores are better: quieter, cheaper and more pleasant.
Another month
