Season planner for Porto Santo
Porto Santo has an Atlantic island pattern with mild air, seasonal water temperature swings, and occasional swell. The warmest, most beach-friendly stretch is typically July to October, with sea temperatures often around 22°C to 23°C. From late autumn through spring, water temperatures are cooler (often near 18°C to 19°C) and swell can limit exposed entries, so operators focus on sheltered sites and pick calm weather windows. Peak visitor season is usually June to October, with quieter months outside that window.
