Avg highs 26°C / 79°F; warm days, cooling nights
September in Lisbon feels like a secret season. You’ll catch the tail end of summer heat, but with smaller lines and cooler evenings. Swim in Atlantic waters still warmed by the August sun, enjoy early harvest wines, and wander Belém or Alfama without jostling crowds. Local festivals, from horror films to Fado, return after the August lull. For best beach days, go early in the month. Don’t skip the Feira da Luz fair in Carnide—a true neighborhood scene.
