Local context
What to expect in September
🎯 Ideal beach temperature (26°C) — crowds still moderate Autumn in Algarve is often underrated: 26°C, golden light and declining crowds. An interesting window. Rain is virtually absent (10% of days) — ideal for planning without a backup. A good balance between weather and crowds, even if July (10.0/10) remains theoretically better.
