What the seasons are actually like
Traveling to Barcelona month by month
Barcelona's comfort score peaks in October at 86.7, with an average high of 22.3°C and 6.5 wet days, narrowly ahead of May's 85 and June's 82.8. July and August are the hottest months, averaging 28.7°C and 29°C, with comfort at 75 and 72.4 — solid, but a step below the shoulder-season peaks, which is part of why RouteVerdict lists them as shoulder months rather than the editorial pick. September also scores well at 79.6, joining April, May, June, and October in the editorial group. Winter (December–February) sees highs of 13.6–15.6°C and comfort scores of 53.7–65.3, mild by comparison with much of Europe.
