Busiest Time to Visit
July–August is peak domestic and European holiday season — Algarve resorts and Lisbon hit capacity, so book well ahead for this window.
Weather vs. Price Trade-off
September keeps summer-level warmth and swimmable sea temperatures at noticeably lower prices than July–August, with the Douro harvest as a bonus — the single strongest value month.
